[0005] However, electrocardiographs are bulky and inconvenient for users to carry around, making it impossible for users to monitor their heart rate anytime and anywhere. Summary of the Invention

[0098] The technical solutions in the embodiments of this application will be clearly and thoroughly described below with reference to the accompanying drawings. In the description of the embodiments of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B; the word "and / or" in the text is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Furthermore, in the description of the embodiments of this application, "multiple" refers to two or more than two.

[0099] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature, and in the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0100] The term "user interface (UI)" used in the following embodiments of this application refers to the medium interface through which an application or operating system interacts and exchanges information with the user. It realizes the conversion between the internal form of information and the form that the user can accept. The user interface is source code written in a specific computer language such as Java or Extensible Markup Language (XML). The interface source code is parsed and rendered on the electronic device, ultimately presenting content that the user can recognize. A common form of user interface is the graphical user interface (GUI), which refers to a user interface related to computer operation displayed graphically. It can be visible interface elements such as text, icons, buttons, menus, tabs, text boxes, dialog boxes, status bars, navigation bars, and widgets displayed on the screen of an electronic device.

[0101] The following describes some terms used in the embodiments of this application.

[0102] Electrocardiogram (ECG): An electrocardiogram is a curve showing the changes in bioelectric potential generated during a heartbeat. It is an important physiological indicator that characterizes the occurrence, propagation, and response of electrical excitation in the heart.

[0103] Electrocardiogram (ECG): During each cardiac cycle, the heart is successively excited by the pacemaker, atria, and ventricles, accompanied by changes in bioelectricity, which are called ECG. The heart pumps blood rhythmically, and its contraction and relaxation rhythm is controlled by cardiac electrical activity. Under normal circumstances, the sinoatrial node regularly sends impulses, which, through a special conduction system, generate electrical impulses throughout the myocardium. The electric field generated by these impulses is distributed throughout the body, and the resulting tiny currents are conducted through body tissues to different locations, causing different potentials in different parts of the body. Therefore, by placing electrodes at different locations on the body surface, the potential difference at different locations can be measured, thus determining the electrocardiogram (ECG).

[0104] Electrode lead system: The electrode lead system is used to indicate the number and arrangement of multiple electrodes used to measure electrocardiogram (ECG). Electrode lead systems can include, but are not limited to, any one or more of the following: the international standard twelve-lead system, the bipolar lead system, etc.

[0105] The international standard 12-lead system: In the international standard 12-lead system, ten electrodes are placed on the body surface. These ten electrodes are located in the left arm (LA), right arm (RA), left leg (LL), right leg (RL), and the remaining six electrodes are located on the chest. The electrode on the right leg can serve as a reference electrode, while the remaining nine electrodes can be used as ECG detection electrodes to measure the electrocardiogram (ECG) signals on the body surface (e.g., the potential difference between different parts of the body surface) and determine the ECG based on the measured signals.

[0106] Bipolar lead system: A bipolar lead system can include three electrodes: a left arm (LA) electrode, a right arm (RA) electrode, and a right leg (RL) electrode. Typically, the left arm electrode is placed on the left arm, the right arm electrode on the right arm, and the right leg electrode on the right leg. It should be noted that these three electrodes can also be placed in other locations on the body. The bipolar lead system acquires the electrocardiogram (ECG) signal on the body surface by measuring the potential difference between the two limbs and determines the ECG based on the measured signal. The left and right arm electrodes are used to acquire the ECG signal on the body surface (e.g., the potential difference between the left and right arms), while the right leg electrode serves as a reference electrode.

[0107] Common-mode interference: During ECG measurement, the right leg can be considered grounded, and the LA and RA electrodes measure ground-based ECG signals. However, the human body has grounding impedance, which introduces common-mode interference, generating common-mode signals. The right leg drive (RLD) circuit can cancel these common-mode signals. The RLD circuit can be connected to the RL electrode to eliminate signals and improve measurement accuracy.

[0108] Right Leg Driven Electrode: The right leg driven (RLD) electrode refers to an RL electrode connected to an RLD circuit. The RLD electrode, LA electrode, and RA electrode can constitute a bipolar lead system for measuring electrocardiogram (ECG) signals. In the embodiments of this application, the electrode used to measure ECG signals can also be referred to as an ECG electrode. When a bipolar lead system is used to measure ECG signals, the ECG electrode may include an LA electrode, a RA electrode, and an RLD electrode.

[0109] Blood sugar: Blood sugar refers to glucose in the blood. Glucose is an important component of the human body and a vital source of energy. A normal human body needs a significant amount of glucose daily to provide energy for the normal functioning of various tissues and organs. Blood sugar must be maintained within a certain range to meet the needs of the body's organs and tissues. Excessively high blood sugar can easily lead to diabetes, while excessively low blood sugar can cause insufficient energy for the body's organs, resulting in serious consequences.

[0110] Blood ketones: Blood ketones refer to the level of ketone bodies in the blood. Muscles and fat produce ketone bodies through exercise metabolism, and these ketone bodies enter the bloodstream. Blood ketone levels within the normal range do not have a negative impact on the body. When blood ketone levels are too high (e.g., above a certain value), the body is at risk of acidosis.

[0111] Blood lactate: Blood lactate refers to the concentration of lactic acid in the blood. Blood lactate is an intermediate product of glucose metabolism in the body, mainly produced by red blood cells, skeletal muscle, and brain tissue. The concentration of lactate in the blood depends primarily on the synthesis rate and metabolic rate of the liver and kidneys. Lactate monitoring refers to measuring the concentration of lactate in the blood, which helps determine whether a user's liver and kidney function are normal.

[0112] Uric acid: Uric acid is the end product of purine metabolism, specifically trioxypurine, and its alcohol form is weakly acidic. The human body contains uric acid, which is excreted through urine. An imbalance between the production and excretion of uric acid in the body can easily lead to elevated blood uric acid levels, thus causing disease. Uric acid is mainly produced in the liver, and most of it is filtered by the glomeruli and excreted in the urine. Therefore, uric acid monitoring helps determine whether a user's liver and kidney functions are normal.

[0113] Electrochemical electrodes: Electrochemical electrodes react with specific substances to generate current or voltage. In the embodiments of this application, electrochemical electrodes can be used to measure one or more physiological parameters, such as blood glucose, blood ketones, uric acid, and blood lactate. Electrochemical electrodes can include various types according to their functions: working electrode, counter electrode, and reference electrode. Multiple electrochemical electrodes with different functions can form an electrochemical system to measure physiological parameters. Common electrochemical systems include two-electrode systems and three-electrode systems.

[0114] Two-electrode system: A two-electrode system may include a working electrode and a counter electrode, or a working electrode and a reference electrode. In a two-electrode system, the working electrode can be used to carry out the reaction under study, and the counter electrode (or reference electrode) can form a circuit with the working electrode and control the voltage of the working electrode.

[0115] Three-electrode system: A three-electrode system may include a working electrode, a reference electrode, and a counter electrode. In a three-electrode system, the working electrode can be used to carry out the reaction under study, the counter electrode can form a circuit with the working electrode, and the reference electrode can control the voltage of the working electrode. Specific examples of the three-electrode system can be found in the embodiment shown in Figure 1A below.

[0116] Continuous glucose monitoring (CGM) devices are electronic devices used to measure blood glucose levels. A CGM device may include an electrochemical electrode containing a glucose enzyme (such as glucose oxidase). After the CGM device is implanted subcutaneously, the glucose enzyme in the electrochemical electrode reacts with glucose in the tissue fluid, generating an electric current. The CGM device measures the current generated by the reaction between the glucose enzyme and glucose, and based on the magnitude of the current, determines the glucose concentration in the user's tissue fluid, and then determines the glucose concentration in the user's blood, i.e., the user's blood glucose level.

[0117] Enzymes: Enzymes are proteins or ribonucleic acid (RNA) produced by living cells that exhibit high specificity and catalytic efficiency towards their substrates. The ability of an enzyme to catalyze a chemical reaction is called enzyme activity (also known as enzyme power). Enzyme activity is temperature-dependent. Different types of enzymes have different optimal temperatures; the enzyme's activity is highest and its catalytic ability is strongest when the temperature of its environment is at its optimal range.

[0118] For example, Figure 1A shows a schematic diagram of a scenario for measuring physiological parameters using a three-electrode system according to an embodiment of this application.

[0119] As shown in Figure 1A, a three-electrode system can include a working electrode, a reference electrode, and a counter electrode. The working electrode (WE), also called the research electrode, is the electrode used to carry out the reaction under study. Taking an electrochemical electrode for measuring blood glucose as an example, the working electrode can contain a substance capable of reacting with glucose (e.g., glucose oxidase), and can be used to generate a reaction current. The counter electrode (CE), also called the auxiliary electrode, can form a circuit with the working electrode to ensure that the current flows through the working electrode, guaranteeing that the reaction under study occurs at the working electrode. The reference electrode (RE) is an electrode with a known potential that is close to ideally non-polarized. Almost no current flows through the reference electrode, which is used to control the voltage of the working electrode.

[0120] When the working electrode, reference electrode, and counter electrode are implanted in subcutaneous tissue, the working electrode can react with the target substance (such as glucose, ketone bodies, uric acid, lactic acid, etc.) to generate a reaction current. By measuring the magnitude of this reaction current, the values ​​of physiological parameters can be determined.

[0188] It should be understood that Figure 2B is only an exemplary illustration of the hardware structure of the electronic device 200. In other embodiments of this application, the electronic device 200 may contain more or fewer components, and this application embodiment does not limit this.

[0189] This application provides a measurement method applied to a first electronic device (also referred to as electronic device 200), the first electronic device including a first electrode group (also referred to as electrode group 1) and a second electrode group (also referred to as electrode group 2), the distance between the first electrode group and the second electrode group being greater than a first distance; when the first electrode group and the second electrode group are implanted in subcutaneous tissue, the method includes: determining a first physiological parameter through the first electrode group; and determining an electrocardiogram signal through the first electrode group and the second electrode group.

[0191] The device form and internal structure of the electronic device 200 provided in the embodiments of this application are described below.

[0192] Figure 3A shows a schematic diagram of the device configuration of an electronic device 200 provided in an embodiment of this application.

[0193] As shown in Figure 3A, the electronic device 200 may include a base shell 301, multiple microneedle sensors, such as microneedle sensor 303 and microneedle sensor 304, and optionally, the electronic device 200 may also include a temperature-sensing heat-conducting column 302. Wherein:

[0194] In some embodiments, the bottom shell 301 can be connected to the temperature-sensing heat-conducting column 302, and the bottom shell 301 can also be connected to the plurality of microneedle sensors. In some embodiments, the temperature-sensing heat-conducting column 302 and the plurality of microneedle sensors can be embedded in the bottom shell 301 or welded to the bottom shell 301. This application does not limit the specific connection method.

[0195] The temperature-sensing heat-conducting column 302 can be used to measure a user's body temperature, such as measuring the user's skin temperature or the temperature of the user's subcutaneous tissue. In some embodiments, the temperature-sensing heat-conducting column 302 can be in contact with the user's skin to measure the user's skin temperature. In some embodiments, the temperature-sensing heat-conducting column 302 can also be implanted into the subcutaneous tissue. In other embodiments, the temperature-sensing heat-conducting column 302 can also be replaced by one or more temperature electrodes, which can also be disposed in the plurality of microneedle sensors and implanted into the subcutaneous tissue.

[0196] Microneedle sensors can be implanted in a user's subcutaneous tissue. Each microneedle sensor may include an electrode assembly, which can be used to measure one or more physiological parameters. Each electrode assembly may include two or more electrochemical electrodes. In some embodiments, the electrode assembly may include one or more working electrodes and one or more counter electrodes (or reference electrodes), which can constitute one or more dual-electrode systems through which one or more physiological parameters can be measured. In other embodiments, the electrode assembly may include one or more working electrodes, one or more counter electrodes, and one or more reference electrodes, which can constitute one or more tri-electrode systems through which one or more physiological parameters can be measured. In other embodiments, optionally, the electrode assembly may also include one or more electrocardiogram (ECG) electrodes, such as one or more of the following: LA electrode, RA electrode, and RLD electrode.

[0197] For example, the plurality of microneedle sensors may include microneedle sensor 303 and microneedle sensor 304. Microneedle sensor 303 may include electrode group 1, and microneedle sensor 304 may include electrode group 2. Electrode group 1 may include at least one working electrode and at least one counter electrode. Optionally, electrode group 1 may also include one or more reference electrodes. Further optionally, electrode group 1 may also include one or more electrocardiogram (ECG) electrodes. Similarly, electrode group 2 may include at least one working electrode and at least one counter electrode. Optionally, electrode group 2 may also include one or more reference electrodes. Further optionally, electrode group 2 may also include one or more ECG electrodes. Electrode group 1 can be used to measure the user's physiological parameters, and electrode group 2 can also be used to measure the user's physiological parameters, which may include, but are not limited to, any one or more of the following: blood glucose, blood ketones, uric acid, blood lactate, etc. The physiological parameters measured by electrode group 1 and electrode group 2 may be the same or different.

[0198] For example, electrode group 1 in microneedle sensor 303 can be used to measure a user's blood glucose, and electrode group 2 in microneedle sensor 304 can be used to measure a user's blood ketones. It is understood that the embodiments described here are merely illustrative of how each microneedle sensor can be used to measure one or more physiological parameters. In the embodiments of this application, microneedle sensors 303 and 304 can also be used to measure physiological parameters different from those described in the above embodiments, and this application does not limit the scope of the application.

[0199] It should be noted that the distance between the microneedle sensor 303 and the microneedle sensor 304 is greater than or equal to a preset distance (e.g., 3 cm). This ensures that the user's electrocardiogram signal can be obtained through these two microneedle sensors.

[0200] It is understood that the embodiment shown in FIG3A is only an example. In the embodiments of this application, the electronic device 200 may also adopt a different device form than the above embodiment, such as including more microneedle sensors than the above embodiment, or including more, fewer or different elements than the above embodiment. This application does not limit it here.

[0201] Figure 3B shows a schematic diagram of the internal structure of an electronic device 200 provided in an embodiment of this application.

[0202] As shown in Figure 3B, the electronic device 200 may include a microneedle sensor 303, a microneedle sensor 304, a printed circuit board (PCB) 305, and a battery 306. Optionally, the electronic device 200 may also include a temperature-sensing heat-conducting pillar 302. Wherein:

[0203] The temperature-sensing heat-conducting column 302 can be connected to the PCB 305 to transmit the measured temperature to the PCB 305. Other specific details of the temperature-sensing heat-conducting column 302 can be found in the relevant description in the embodiment shown in Figure 3A above, and will not be repeated here.

[0204] The microneedle sensor 303 can be equipped with an electrode assembly 1, which may include multiple electrochemical electrodes, such as a working electrode (WE) 3031 and a counter electrode (CE) 3033. Optionally, the electrode assembly 1 may also include a reference electrode (RE) 3032. The electrode assembly 1 is used to measure physiological parameter 1 (e.g., blood glucose, blood ketones, uric acid, blood lactate, etc.). In the electrode assembly 1, the working electrode 3031 can react with the target substance 1 corresponding to the physiological parameter 1 to generate a reaction current. For example, if the physiological parameter 1 is blood glucose, the target substance 1 can be glucose; or, for example, if the physiological parameter 1 is blood ketones, the target substance can be ketone bodies, etc. The reference electrode 3032 can be used to control the voltage of the working electrode 3031. The counter electrode 3033 can be used to form a circuit with the working electrode 3031 to ensure the generation and conduction of the reaction current. In some embodiments, the electrode assembly 1 can form a dual-electrode system through the working electrode 3031 and the counter electrode 3033, and form a circuit through this dual-electrode system to ensure the generation and conduction of the reaction current. In other embodiments, electrode assembly 1 can be configured as a three-electrode system consisting of a working electrode 3031, a counter electrode 3033, and a reference electrode 3032, forming a circuit to ensure the generation and conduction of the reaction current. This two-electrode system and the three-electrode system can be used to measure physiological parameter 1.

[0205] The microneedle sensor 304 can be equipped with an electrode group 2, which may include multiple electrochemical electrodes, such as a working electrode (WE) 3041 and a counter electrode (CE) 3043. Optionally, the electrode group 2 may also include a reference electrode (RE) 3042. The electrode group 2 is used to measure physiological parameter 2 (e.g., blood glucose, blood ketones, uric acid, blood lactate, etc.). It should be noted that physiological parameter 1 may be different from physiological parameter 2; in some embodiments, physiological parameter 1 may also be the same as physiological parameter 2. The function of each electrode in the electrode group 2 can be compared with the function of each electrode in the electrode group 1 described above. The electrode group 2 may also be configured as a two-electrode system or a three-electrode system based on the type and number of electrochemical electrodes, and physiological parameter 2 can be measured through the two-electrode system or the three-electrode system.

[0206] Electrode sets 1 and 2 can also be used to measure the user's electrocardiogram (ECG) signals.

[0207] In some embodiments, the electrochemical electrodes in electrode group 1 and electrode group 2 can be used as electrocardiogram (ECG) electrodes to measure ECG signals. Any electrode in electrode group 1 and any electrode in electrode group 2 can be used as an LA electrode and RA electrode, respectively. The RLD electrode can be an electrode in electrode group 1 or an electrode in electrode group 2, and the RLD electrode is connected to a right leg drive circuit, which is used to cancel common-mode signals. For example, RE3032 in microneedle sensor 303 can be used as an LA electrode, WE3041 in microneedle sensor 304 can be used as an RA electrode, and CE3043 can be used as an RLD electrode. It is understood that the embodiments described here are merely examples. In the embodiments of this application, other electrodes in electrode group 1 and electrode group 2 can also be selected as ECG electrodes to measure ECG signals; this application does not limit this. In the above cases, some electrochemical electrodes in electrode group 1 and electrode group 2 can measure both the user's physiological parameters and the user's ECG signals.

[0208] In other embodiments, separate ECG electrodes can be provided in electrode groups 1 and 2 for measuring ECG signals. Specifically, the LA and RA electrodes are located in different electrode groups, while the RLD electrode can be located in either electrode group. In this case, ECG signals can be measured using these electrodes, and these electrodes are used solely for measuring ECG signals.

[0209] In other embodiments, electrode groups 1 and 2 may each contain individual electrocardiogram (ECG) electrodes. Furthermore, some of the electrochemical electrodes in electrode groups 1 and 2 may also be used as ECG electrodes. For example, electrode group 1 may contain an RLD electrode, and one of the electrochemical electrodes in electrode group 1 and electrode group 2 may be selected as the LA electrode and RA electrode, respectively. Thus, ECG signals can be measured using the RLD electrode and multiple electrochemical electrodes. It is understood that this is merely illustrative, and some electrodes in the ECG array may use the electrochemical electrodes in electrode groups 1 and 2. In the embodiments of this application, more, fewer, or different ECG electrodes than those described in the above embodiments may be provided, or other electrochemical electrodes may be used as ECG electrodes to measure ECG signals. This application does not impose any limitations on this.

[0210] PCB 305 can acquire the user's electrocardiogram (ECG) signal through microneedle sensors 303 and 304. It can also acquire the user's physiological data 1 through microneedle sensor 303, which is used to determine physiological parameter 1. PCB 305 can also acquire the user's physiological data 2 through microneedle sensor 304, which can be used to determine physiological parameter 2. PCB 305 may include multiple circuit modules. The internal circuit structure of these modules and the connection relationships between them can be referred to the relevant content in the embodiments shown in Figures 4A-4J below, and will not be detailed here.

[0211] Battery 306 can be used to power multiple modules in electronic device 200, such as powering PCB 305. In some embodiments, battery 306 can be a lithium battery, and in other embodiments, battery 306 can also be a battery made of other materials, which is not limited herein.

[0212] It is understood that the embodiment shown in Figure 3B above is only an example. In some embodiments, the electronic device 200 may also include more microneedle sensors than in the above embodiment, and the microneedle sensors may also include more or fewer electrochemical electrodes than in the above embodiment. This application does not limit the scope of the invention.

[0213] Figure 3C shows a schematic diagram of the electrode distribution on a microneedle sensor 303 provided in an embodiment of this application.

[0214] As shown in Figure 3C, the microneedle sensor 303 may include a supradermal portion and a subcutaneous portion. The subcutaneous portion is for implantation into the user's subcutaneous tissue, and the supradermal portion is for connection to the PCB 305. For example, the microneedle sensor 303 may be an irregularly shaped sheet that may include two opposing surfaces, namely surface A and surface B.

[0215] An electrode assembly 1 may be disposed on the microneedle sensor 303. A detailed description of the electrode assembly 1 can be found in the embodiments shown in Figures 3A and 3B. Exemplarily, the electrode assembly 1 may include a working electrode 3031, a reference electrode 3032, and a counter electrode 3033. In some embodiments, all electrochemical electrodes in the electrode assembly 1 may be disposed on surface A of the microneedle sensor 303. Each electrochemical electrode may include a measuring end, a conducting end, and a wire for connecting the measuring end and the conducting end. The measuring ends of the one or more electrochemical electrodes are disposed on surface A of the subcutaneous portion, and the conducting ends of the one or more electrochemical electrodes are disposed on surface A of the supracutaneous portion.

[0216] It is understood that the embodiment shown in Figure 3A is merely an illustrative example illustrating that all electrodes on the microneedle sensor 303 can be disposed on the same surface of the microneedle sensor 303. In other embodiments, the electrodes on the microneedle sensor 303 can also be disposed on different surfaces of the microneedle sensor 303, for example, the working electrode 3031 can be disposed on surface A, and the reference electrode 3032 and the counter electrode 3033 can be disposed on surface B. This application does not limit this. Furthermore, in other embodiments, the microneedle sensor 303 can also adopt a different shape than that shown in Figure 3C, such as needle-shaped, cylindrical, triangular prism, polyhedral, etc. This application does not limit the specific shape of the microneedle sensor 303.

[0217] Thus, when the microneedle sensor 303 is implanted in the subcutaneous tissue of the user, the microneedle sensor 303 can acquire the user's physiological data 1 through one or more electrochemical electrodes.

[0218] In other embodiments, the microneedle sensor 303 may also include multiple working electrodes. In one possible implementation, two or more working electrodes may share the same reference electrode and / or counter electrode, forming different three-electrode systems (or two-electrode systems) to measure the same or different physiological parameters, such as blood glucose and blood ketones. In another possible implementation, the microneedle sensor 303 may also include multiple reference electrodes and / or counter electrodes. These multiple working electrodes may form different three-electrode systems (or two-electrode systems) with different reference electrodes and / or counter electrodes to measure the same or different physiological parameters.

[0219] It should be noted that the electrode distribution on the microneedle sensor 304 can also refer to the electrode distribution of the microneedle sensor 303 shown in Figure 3C above. In addition, if the electronic device 200 also includes other microneedle sensors, the electrode distribution on the microneedle sensor can also refer to the relevant description in the embodiment shown in Figure 3C above. This application will not repeat it here.

[0220] Figure 3D shows a schematic diagram of the device configuration of another electronic device 200 provided in an embodiment of this application.

[0221] As shown in Figure 3D, the electronic device 200 may include a base shell 301 and multiple array sensors. Each array sensor may include an electrode group. The specific details of the electrode group can be found in the relevant description in the embodiment shown in Figure 3A above, and will not be repeated here. Optionally, the electronic device 200 may also include a temperature-sensing heat-conducting column 302. The specific details of the temperature-sensing heat-conducting column 302 can be found in the relevant description in the embodiments shown in Figures 3A-3B above, and will not be repeated here. In some embodiments, the multiple array sensors may be disposed on the base shell 301, and optionally, a temperature-sensing heat-conducting column 302 may also be disposed thereon. In the embodiments of this application, a sensor may refer to a component used to acquire a specific signal (e.g., current signal, voltage signal, light signal, etc.). In some embodiments, an array sensor may also refer to multiple electrodes arranged in an array.

[0222] For example, the plurality of array sensors may include array sensor 307 and array sensor 308. Array sensor 307 may include electrode group 1, and array sensor 308 may include electrode group 2.

[0223] Electrode group 1 may include multiple electrochemical electrodes, such as a working electrode group 3073 and a counter electrode group 3075, and optionally, a reference electrode group 3074. Further optionally, it may include one or more electrocardiogram electrodes, such as a right leg drive (RLD) electrode 3072 and a right arm (RA) electrode 3071. Each electrode group may include one or more electrochemical electrodes of the same type. In some embodiments, the working electrode group 3073 and the counter electrode group 3075 in electrode group 1 may constitute one or more dual-electrode systems, each dual-electrode system forming a circuit to ensure the generation and conduction of reaction current. Through this dual-electrode system, electrode group 1 can measure one or more physiological parameters. In other embodiments, the working electrode group 3073, the reference electrode group 3074, and the counter electrode group 3075 in electrode group 1 may constitute one or more three-electrode systems, each three-electrode system forming a circuit to ensure the generation and conduction of reaction current. It should be noted that in some embodiments, multiple dual-electrode systems (or three-electrode systems) may share a counter electrode and / or a reference electrode. Using a two-electrode system and / or a three-electrode system, electrode group 1 can measure physiological parameters 1.

[0224] Electrode group 2 may include multiple electrochemical electrodes, such as a working electrode group 3082 and a counter electrode group 3084, and optionally, a reference electrode group 3083. Further optionally, it may include one or more electrocardiogram electrodes, such as a left arm (LA) electrode 3081. Each electrode group may include one or more electrochemical electrodes of the same type. In some embodiments, the working electrode group 3082 and the counter electrode group 3084 in electrode group 2 may constitute one or more dual-electrode systems, each dual-electrode system forming a circuit to ensure the generation and conduction of reaction current. Through this dual-electrode system, electrode group 2 can measure one or more physiological parameters. In other embodiments, the working electrode group 3082, the reference electrode group 3083, and the counter electrode group 3084 in electrode group 2 may constitute one or more tri-electrode systems, each tri-electrode system forming a circuit to ensure the generation and conduction of reaction current. It should be noted that in some embodiments, multiple dual-electrode systems (or tri-electrode systems) may share a counter electrode and / or a reference electrode. Through the dual-electrode system and / or the tri-electrode system, electrode group 2 can measure physiological parameter 2.

[0225] It is understood that the above embodiments are merely illustrative of the fact that electrode group 1 and electrode group 2 may include one or more ECG electrodes. In the embodiments of this application, it is only necessary to ensure that the LA electrode and RA electrode are located in different electrode groups, and the RLD electrode can be located in any electrode group. This application does not limit the specific correspondence between ECG electrodes and electrode groups.

[0226] In other embodiments, separate ECG electrodes may be provided in electrode groups 1 and 2, such as a left arm (LA) electrode 3081, a right leg drive (RLD) electrode 3072, and a right arm (RA) electrode 3071. In this case, ECG signals can be measured using the ECG electrodes, and the aforementioned ECG electrodes are used solely for measuring ECG signals.

[0227] In some embodiments, the electrochemical electrodes in electrode group 1 and electrode group 2 can be used as ECG electrodes to measure ECG signals. Any electrode in electrode group 1 and any electrode in electrode group 2 can serve as an LA electrode and RA electrode, respectively. The RLD electrode can be an electrode in electrode group 1 or an electrode in electrode group 2, and the RLD electrode is connected to a right leg drive circuit, which is used to cancel common-mode signals. For example, one or more reference electrodes in the reference electrode group 3074 in electrode group 1 can serve as LA electrodes, one or more working electrodes in the working electrode group 3082 in electrode group 2 can serve as RA electrodes, and one or more counter electrodes in the counter electrode group 3084 can serve as RLD electrodes. It is understood that the embodiments described here are merely examples. In the embodiments of this application, other electrodes in electrode group 1 and electrode group 2 can also be selected as ECG electrodes to measure ECG signals; this application does not limit this. In the above cases, some electrochemical electrodes in electrode group 1 and electrode group 2 can measure both the user's physiological parameters and the user's ECG signals.

[0228] In other embodiments, electrode groups 1 and 2 may each contain a separate electrocardiogram (ECG) electrode. Furthermore, some of the electrochemical electrodes in electrode groups 1 and 2 can also be used as ECG electrodes. For example, electrode group 1 may contain an RLD electrode, and one of the electrochemical electrodes in electrode groups 1 and 2 may be selected as the LA electrode and RA electrode, respectively. Thus, ECG signals can be measured using the RLD electrode and multiple electrochemical electrodes. It is understood that this is merely illustrative; some electrodes in the ECG electrode set may use the electrochemical electrodes in electrode groups 1 and 2. In the embodiments of this application, other electrochemical electrodes may also be used as ECG electrodes to measure ECG signals, and this application does not impose limitations.

[0229] In the array sensors 307 and 308 described above, the specific functions of the working electrode, reference electrode, and counter electrode can be compared with the functional descriptions of each electrode in the embodiment shown in Figure 3B above, and will not be repeated here.

[0230] It should be noted that the distance between array sensor 307 and array sensor 308 is greater than or equal to a preset distance (e.g., 3 cm), which ensures that the user's electrocardiogram signal can be obtained through these two array sensors.

[0231] It is understood that the embodiment shown in Figure 3D is only an example. In the embodiments of this application, the electronic device 200 may also adopt a device form different from the above embodiments. For example, it may include more array sensors than the above embodiments, or include more, fewer or different electrodes (including electrocardiogram electrodes and electrochemical electrodes) than the above embodiments, or include more, fewer or different elements than the above embodiments. This application does not limit it.

[0232] It should be noted that the embodiments shown in Figures 3A and 3D above are only two examples. In the embodiments of this application, the electronic device 200 may also include one or more array sensors and one or more microneedle sensors. The microneedle sensor may include multiple electrodes, and the array sensor may also include multiple electrodes. The electronic device 200 may also determine one physiological parameter through an array sensor and another physiological parameter through a microneedle sensor. It may also acquire electrocardiogram signals through the microneedle sensor and the array sensor. This application does not limit this.

[0257] The voltage regulator circuit 4094 can provide stable power to other circuit modules in PCB 305. The voltage regulator circuit 4094 can receive power from the charging management chip 4092 and also from the battery 4093.

[0258] It is understood that the embodiment shown in Figure 4A is only an example. In the embodiments of this application, PCB305 may also include more, fewer or different circuit modules (e.g., electrochemical circuit modules, electrode interfaces, etc.) than the above embodiments. Moreover, the connection relationship between the circuit modules in PCB305 may also be a different connection relationship than the above embodiments. This application does not limit this.

[0259] In some embodiments, the same electrochemical circuit module in PCB305 can be used to measure multiple physiological parameters, and PCB305 can control the physiological parameters measured by the electrochemical circuit module through one or more switching switches.

[0260] For example, Figure 4B shows a schematic diagram of the connection relationship of various circuit modules in another PCB305 provided in an embodiment of this application.

[0261] As shown in Figure 4B, PCB 305 may include a microcontroller unit (MCU), an analog-to-digital converter (ADC) 402, an electrocardiogram (ECG) circuit module 403, a switching switch MUX0, one or more electrochemical circuit modules (e.g., electrochemical circuit module 404), one or more electrode interfaces (e.g., electrode interface 406, electrode interface 407), etc. Optionally, PCB 305 may also include, but is not limited to, any one or more of the following: a temperature module 408, a charging circuit module 409, etc. Wherein:

[0262] The input terminal of the switch MUX0 can be connected to electrode interface 406 and electrode interface 407. The output terminal of the switch MUX0 can be connected to electrochemical circuit module 404. The switch MUX0 can activate either electrode interface 406 or electrode interface 407.

[0263] The electrochemical circuit module 404 can be connected to multiple electrochemical electrodes via the switching switch MUX0.

[0264] When MUX0 is connected to electrode interface 406, electrochemical circuit module 404 can connect one or more electrochemical electrodes through MUX0 and electrode interface 406. In the case of measuring physiological parameters using a three-electrode system, these one or more electrochemical electrodes may include one or more working electrodes, one or more reference electrodes, and one or more counter electrodes. These one or more electrochemical electrodes can react with target substance 1 to generate current signal 1, and transmit this current signal 1 to electrochemical circuit module 404. Electrochemical circuit module 404 can amplify and process this current signal 1 to obtain current signal 2, and send current signal 2 to ADC 402.

[0265] When the MUX0 is connected to the electrode interface 407, the electrochemical circuit module 404 can connect one or more electrochemical electrodes through the MUX0 and the electrode interface 407. In the case of measuring physiological parameters using a three-electrode system, these one or more electrochemical electrodes may include one or more working electrodes, one or more reference electrodes, and one or more counter electrodes. These one or more electrochemical electrodes can react with the target substance 2 to generate a current signal 3, which is then transmitted to the electrochemical circuit module 404. The electrochemical circuit module 404 can amplify and process the current signal 3 to obtain a current signal 4, which is then sent to the ADC 402.

[0266] In some embodiments, the electrochemical circuit module 404 may include a potentiostat circuit 4041 and a transresistance circuit 4042. The potentiostat circuit 4041 can control the voltage difference between the reference electrode and the working electrode. The transresistance circuit 4042 can amplify the current signal, for example, amplifying current signal 1 to obtain current signal 2, or amplifying current signal 3 to obtain current signal 4. In some embodiments, there may be overlap between the potentiostat circuit 4041 and the transresistance circuit 4042, for example, there may be one or more components shared by the potentiostat circuit 4041 and the transresistance circuit 4042. Specific examples can be found in the embodiments shown in Figures 4C-4D and 4F-4J below, which will not be detailed here.

[0267] The one or more electrode interfaces may include electrode interface 406 and electrode interface 407. The electrode interfaces can connect the electrochemical circuit module to one or more electrochemical electrodes, and can also connect the ECG circuit module 403 to the ECG electrodes.

Electrode interface 407 can connect the switching switch MUX0 to one or more electrochemical electrodes, and electrode interface 407 can also connect the ECG circuit module 403 to the RA electrode and the RLD electrode. The connection relationships between electrode interfaces 406 and 407 and the various electrodes can be referred to the relevant descriptions in the embodiments shown in Figure 4A above, and will not be repeated here.

[0268] Furthermore, the specific details of MCU401, ADC402, ECG circuit module 403, temperature module 408, and charging circuit module 409 can be found in the relevant descriptions in the embodiment shown in Figure 4A above, and will not be repeated here.

[0269] It is understood that the embodiment shown in Figure 4B is merely an example. In the embodiments of this application, PCB305 may also include more, fewer, or different circuit modules (e.g., electrochemical circuit modules, electrode interfaces, etc.) than the above embodiments. Moreover, the connection relationships between the circuit modules in PCB305 may also be different from those in the above embodiments, and this application does not impose any limitations on them. Furthermore, in some embodiments, a single electrochemical module may be used to measure two or more physiological parameters, and this application does not impose any limitations on it either.

[0270] In other embodiments, the PCB305 may have more or fewer switching switches, or the switching switches may be set at different locations than those in the embodiment shown in FIG4B above. These switching switches can be used to control the PCB305 to measure current signals / ECG signals of specified physiological parameters at the same time, or to measure ECG signals and current signals of one or more physiological parameters at the same time.

[0271] The following section uses the example of electrode group 1 and electrode group 2 both constituting a three-electrode system to introduce various measurement circuits provided in the embodiments of this application.

[0272] Figure 4C shows a circuit diagram of a measurement circuit provided in an embodiment of this application.

[0273] As shown in Figure 4C, the measurement circuit may include a potentiostat circuit 1, a transimpedance circuit 1, a potentiostat circuit 2, a transimpedance circuit 2, a right leg drive circuit, an amplifier circuit, a filter circuit, an analog-to-digital converter (ADC) module, and an MCU, etc. Optionally, the measurement circuit may also include any one or more of the following: a Discrete Fourier Transform (DFT) module and a temperature module (temp), etc. Furthermore, the measurement circuit may include multiple electrode groups, such as electrode group 1 and electrode group 2. For example, electrode group 1 may include a working electrode W1, a reference electrode R1, and a counter electrode C1; electrode group 2 may include a working electrode W2, a reference electrode R2, and a counter electrode C2.

[0274] The components in each circuit module and their connection methods are described below.

[0275] The potentiostat circuit 1 may include a digital-to-analog converter module DAC1, operational amplifier AMP_1, and operational amplifier AMP_2. Each operational amplifier may include a non-inverting input, an inverting input, and an output. DAC1 generates a stable voltage signal. DAC1 can be connected to the non-inverting input of operational amplifier AMP_1 and also to the non-inverting input of operational amplifier AMP_2, providing the same voltage input to both operational amplifiers AMP_1 and AMP_2. The output of operational amplifier AMP_1 can be connected to the counter electrode C1 in electrode group 1, and the inverting input of operational amplifier AMP_1 can be connected to the reference electrode R1 in electrode group 1. The inverting input of operational amplifier AMP_2 can be connected to the working electrode W1 in electrode group 1, and the output of operational amplifier AMP_2 can be connected to the ADC. Thus, by applying the same voltage to the non-inverting inputs of operational amplifiers AMP_1 and AMP_2, the voltage difference between the reference electrode R1 and the working electrode W1 can be controlled, making the voltage on the working electrode W1 approximately equal to the voltage on the reference electrode R1.

[0276] The transimpedance circuit 1 may include an operational amplifier AMP_2 and a resistor RTIA_1. The two ends of the resistor RTIA_1 are connected to the inverting input and output terminals of the operational amplifier AMP_2, respectively. Thus, when there is a stable voltage input to the non-inverting input terminal of the operational amplifier AMP_2, the transimpedance circuit 1 can amplify the current signal input to the inverting input terminal of the operational amplifier AMP_2. Since the inverting input terminal of the operational amplifier AMP_2 is connected to the working electrode W1 in electrode group 1, and the output terminal of the operational amplifier AMP_2 is connected to an ADC, the transimpedance circuit 1 can amplify the current signal conducted through the working electrode W1 and transmit the amplified current signal to the ADC.

[0277] The potentiostat circuit 2 may include a digital-to-analog converter module DAC2, operational amplifier AMP_5, and operational amplifier AMP_6. DAC2 generates a stable voltage signal. DAC2 can be connected to the non-inverting input of operational amplifier AMP_5 and also to the non-inverting input of operational amplifier AMP_6, providing the same voltage input to both operational amplifiers AMP_5 and AMP_6. The output of operational amplifier AMP_5 can be connected to the counter electrode C2 in electrode group 2, and the inverting input of operational amplifier AMP_5 can be connected to the reference electrode R2 in electrode group 2. The inverting input of operational amplifier AMP_6 can be connected to the working electrode W2 in electrode group 2, and the output of operational amplifier AMP_6 can be connected to the ADC. Thus, by applying the same voltage to the non-inverting inputs of operational amplifiers AMP_5 and AMP_6, the voltage difference between the reference electrode R2 and the working electrode W2 can be controlled, making the voltage on the working electrode W2 approximately equal to the voltage on the reference electrode R2. It should be noted that in some embodiments, the potentiostat circuit 2 may share a digital-to-analog converter module DAC1 with the potentiostat circuit 1. In this case, the digital-to-analog converter module DAC2 in the potentiostat circuit 2 may also be replaced by the digital-to-analog converter module DAC1. This application does not limit this.

[0278] The transimpedance circuit 2 may include an operational amplifier AMP_6 and a resistor RTIA_2. The two ends of the resistor RTIA_2 are connected to the inverting input and output terminals of the operational amplifier AMP_6, respectively. Thus, when there is a stable voltage input to the non-inverting input terminal of the operational amplifier AMP_6, the transimpedance circuit 2 can amplify the current signal input to the inverting input terminal of the operational amplifier AMP_6. Since the inverting input terminal of the operational amplifier AMP_6 is connected to the working electrode W2 in electrode group 2, and the output terminal of the operational amplifier AMP_6 is connected to an ADC, the transimpedance circuit 2 can amplify the current signal conducted through the working electrode W2 and transmit the amplified current signal to the ADC.

[0279] The amplification module may include an instrumentation amplifier IA, which can be a component integrated from multiple operational amplifiers. The instrumentation amplifier IA may include a non-inverting input, an inverting input, and an output. The instrumentation amplifier IA performs differential operations on the signals from the non-inverting and inverting inputs, amplifying the differential-mode signal between them. Simultaneously, the instrumentation amplifier IA only acts as a follower for the common-mode signal, thereby increasing the ratio between the amplitudes of the differential-mode and common-mode signals and suppressing common-mode signals. The non-inverting input of the instrumentation amplifier IA can be connected to the reference electrode R1 in electrode group 1, and the inverting input can be connected to the working electrode W2 in electrode group 2. In this case, the reference electrode R1 can be considered as the LA electrode, and the working electrode W2 can be considered as the RA electrode. Thus, the instrumentation amplifier IA can amplify the potential difference between the LA and RA electrodes and transmit the amplified ECG signal to the filtering circuit.

[0280] In some embodiments, the right leg drive circuit may include an operational amplifier AMP_3, multiple resistors, and a capacitor C1. The multiple resistors may include resistors R1, R2, R3, and R4. The non-inverting input of operational amplifier AMP_3 can be connected to a voltage source VCM_REF, which can apply a stable voltage to operational amplifier AMP_3. The inverting input of operational amplifier AMP_3 can be connected to instrumentation amplifier IA via resistor R2 to receive the common-mode signal output by instrumentation amplifier IA. Furthermore, the output of operational amplifier AMP_3 can be connected to the counter electrode C2 in electrode group 2 via resistor R1; in this case, counter electrode C2 can be considered as the RLD electrode. The two ends of resistor R3 can be connected to the output and inverting input of operational amplifier AMP_3, respectively. The two ends of resistor R4 are connected to capacitor C1 and the output of operational amplifier AMP_3, respectively. The two ends of capacitor C1 are connected to resistor R4 and the inverting input of operational amplifier AMP_3, respectively. That is, resistor R4 and capacitor C1 are connected in series, and the branch formed by the series connection of resistor R4 and capacitor C1 is connected in parallel with resistor R3. The right leg drive circuit can apply an inverted signal of the common-mode signal through the RLD electrode, thereby canceling the common-mode signal.

[0281] The filtering circuit may include multiple filters, such as filter1 and filter2, and optionally, an operational amplifier AMP_4. In some embodiments, filter1 may be connected to the output of instrumentation amplifier IA and the input of operational amplifier AMP_4, and filter2 may be connected to the output of operational amplifier AMP_4 and the input of ADC. The filtering circuit can receive the amplified ECG signal sent by the amplification circuit, perform one or more operations such as filtering and amplification on the amplified ECG signal, and send the processed ECG signal to ADC.

[0282] The DFT module is optional. The DFT can process the digital signal transmitted by the ADC and then transmit it to the MCU.

[0283] The specific functions of the ADC, MCU, and temperature module temp can be found in the descriptions in the embodiments shown in Figure 4A or Figure 4B above, and will not be repeated here.

[0284] It should be noted that in the embodiment shown in FIG4C, electrode group 1 and electrode group 2 can be electrode group 1 and electrode group 2 in the embodiments shown in FIG3A-FIG3B or FIG3D-FIG3E.

[0287] As shown in Figure 4D, the measurement circuit may include a potentiostat circuit 1, a transimpedance circuit 1, a potentiostat circuit 2, a transimpedance circuit 2, a right leg drive circuit, an amplifier circuit, a filter circuit, an analog-to-digital converter (ADC) module, and an MCU, etc. Optionally, the measurement circuit may also include one or more of the following: a Discrete Fourier Transform (DFT) module and a temperature module (temp), etc. Furthermore, the measurement circuit may include multiple electrode groups, such as electrode group 1 and electrode group 2.

[0349] The specific functional descriptions of each module in the measurement circuit can be found in the relevant descriptions in the embodiment shown in Figure 4H above, and will not be repeated here.

[0350] It is understood that the embodiment shown in Figure 4I above is only an example. In the embodiments of this application, the measurement circuit may also include more electrode groups, potentiostat circuits, and transimpedance circuits. The switching switch may also include more input terminals and output terminals, or it may include more switching switches to control the measurement of more physiological parameters.

[0368] S501. Electronic equipment 200 determines that monitoring condition 1 is met and determines physiological parameters 1.

[0369] Monitoring condition 1 may include, but is not limited to, any one or more of the following: receiving information 1 sent by other electronic devices to instruct electronic device 200 to detect physiological parameters 1; detecting that the user is wearing electronic device 200 (i.e., the electrodes of electronic device 200 are implanted in the user's subcutaneous tissue); detecting abnormal electrocardiogram signals.

[0370] For example, electronic device 200 can determine whether it is being worn by a user based on whether the temperature detected by a temperature sensor falls within a preset body temperature range. It is understood that this embodiment is merely an example, and other methods may be used to determine whether electronic device 200 is being worn in this application; this application does not limit such methods.

[0371] Physiological parameter 1 may include, but is not limited to, any one or more of the following: blood glucose, blood ketones, blood lactate, uric acid, etc.

[0372] In one possible implementation, when monitoring condition 1 is determined to be met, the electronic device 200 can measure physiological parameter 1, and stop monitoring after determining physiological parameter 1. In another possible implementation, when monitoring condition 1 is determined to be met, the electronic device 200 can periodically detect physiological parameter 1, for example, determining the value of physiological parameter 1 at the current moment every 10 minutes (or 20 minutes, 30 minutes, etc.). It should be noted that in this case, different physiological parameters may correspond to different monitoring cycles or the same monitoring cycle; this application does not impose any limitations on this.

[0373] The electronic device 200 can obtain the reaction current generated by the reaction with the target substance 1 through the electrochemical electrode corresponding to the physiological parameter 1, and determine the physiological parameter 1 based on the magnitude of the reaction current.

[0374] For example, if physiological parameter 1 is blood glucose, and the electrochemical electrode for measuring blood glucose includes the working electrode 3031, reference electrode 3032, and counter electrode 3033 of the microneedle sensor 303 shown in Figure 3B, then when the microneedle sensor 303 is implanted in subcutaneous tissue, the working electrode 3031 can react with glucose to generate a reaction current. The electronic device 200 can acquire the magnitude of this reaction current and determine the blood glucose value based on the magnitude of the reaction current using a blood glucose calculation model stored in the electronic device 200.

[0375] For example, if physiological parameter 1 is blood glucose, and the electrochemical electrodes for measuring blood glucose include the working electrode group 3073, the reference electrode group 3074, and the counter electrode group 3075 in the array sensor 307 shown in Figure 3D, then when the array sensor 307 is implanted in subcutaneous tissue, the working electrode group 3073 can react with glucose to generate a reaction current. The electronic device 200 can acquire the magnitude of this reaction current and determine the blood glucose value based on the magnitude of the reaction current using a blood glucose calculation model stored in the electronic device 200.

[0376] It is understood that the embodiments described here are only two examples. In the embodiments of this application, physiological parameter 1 may also be other physiological parameters different from blood glucose, or may include multiple physiological parameters. This application does not limit this.

[0377] Optionally, the electronic device 200 can also measure the user's body temperature. In this case, the electronic device 200 can further optionally calibrate the value of physiological parameter 1 based on the user's body temperature.

[0378] S502. Electronic device 200 outputs physiological parameters 1.

[0379] In some embodiments, the electronic device 200 may include (or be connected to) an audio module and / or a display screen. In this case, the electronic device 200 may output physiological parameter 1 by voice broadcast through the audio module or by displaying physiological parameter 1 through the display screen.

[0380] In other embodiments, the electronic device 200 outputs physiological parameter 1, or it may send output information 1 to other electronic devices (such as electronic device 100). The output information 1 may include physiological parameter 1 and can be used to instruct the receiving end to output the physiological parameter 1.

[0381] In some embodiments, while outputting the user's physiological parameter 1 (or after outputting the physiological parameter 1), the electronic device 200 may also output any one or more of the following: evaluation results, value range, user status, historical curves, reference suggestions, etc. The specific descriptions and determination methods of each item can be referred to the relevant descriptions in step S605 shown in Figure 6 below, which will not be detailed here.

[0382] S503. Electronic device 200 determines that monitoring condition 2 is met and acquires electrocardiogram signal.

[0383] It should be noted that there is no limitation on the execution order of step S503 and the above step S501. The electronic device 200 can execute step S501 and step S503 at the same time, or it can execute one step first and then the other step. This application does not limit this.

[0384] Monitoring condition 2 may include, but is not limited to, any one or more of the following: receiving information 2 sent by other electronic devices to instruct electronic device 200 to detect electrocardiogram signals; detecting bio-wearable electronic device 200 (i.e., the electrodes of electronic device 200 are implanted in subcutaneous tissue); detecting abnormal physiological parameter 1, etc.

[0385] Here, "abnormal physiological parameter 1" refers to a value of physiological parameter 1 that does not belong to a preset value range for physiological parameter 1. This value range can be pre-stored by the electronic device 200. For example, the electronic device 200 can start acquiring electrocardiogram (ECG) signals when it detects that the user's blood glucose level exceeds a preset blood glucose value range. It is understood that this embodiment is only an illustrative example illustrating whether to acquire ECG signals can be determined by the value of physiological parameters. In this application embodiment, physiological parameter 1 can also be other physiological parameters different from blood glucose, or it can include multiple physiological parameters. This application does not limit this.

[0386] It should be noted that during the acquisition of electrocardiogram (ECG) signals, the ECG electrodes used to measure these signals can be implanted in subcutaneous tissue. In some embodiments, these ECG electrodes can be electrochemical electrodes in electronic device 200 used to measure other physiological parameters.

[0387] For example, if the electronic device 200 is the electronic device 200 in the embodiment shown in FIG. 3B above, then the ECG electrode can be a portion of the electrochemical electrodes in the microneedle sensor 303 and microneedle sensor 304. For example, the LA electrode can be the reference electrode 3032, the RA electrode can be the working electrode 3041, and the RLD electrode can be the counter electrode 3043. As another example, if the electronic device 200 is the electronic device 200 in the embodiment shown in FIG. 3D above, then the ECG electrode can be the ECG electrode in the array sensor 307 and array sensor 308. For example, the LA electrode can be the LA electrode 3081, the RA electrode can be the RA electrode 3071, and the RLD electrode can be the RLD electrode 3072. It is understood that the embodiments here are only two examples. In the embodiments of this application, when the ECG electrode and the electrochemical electrode share the same electrode, the correspondence between the ECG electrode and the electrochemical electrode can also be different from the above embodiments. This application does not limit this relationship.

[0388] In a bipolar lead system, the electrocardiogram (ECG) signal can refer to the voltage difference between the LA and RA electrodes within a preset time period (e.g., 1 minute, 3 minutes, etc.). When the electronic device 200 uses other lead systems to measure the ECG signal, the ECG signal can also be the voltage difference between other electrodes within a preset time period, and this application does not limit it here.

[0389] For example, Figure 5B shows a waveform diagram of an electrocardiogram signal provided in an embodiment of this application.

[0390] As shown in Figure 5B, a two-dimensional coordinate system can include a horizontal axis and a vertical axis. The horizontal axis can represent time, and the vertical axis can represent voltage. The electrocardiogram (ECG) signal waveform can be represented by curve Q in this two-dimensional coordinate system. According to curve Q, the ECG signal waveform exhibits periodic fluctuations as the heart pumps blood periodically.

[0391] It is understood that the embodiment shown in Figure 5B is only an example. In the embodiments of this application, the waveform of the electrocardiogram signal may also be different from the waveform of the above embodiment. This application does not limit it here.

[0392] S504. Electronic device 200 outputs electrocardiogram signal.

[0393] In some embodiments, the electronic device 200 may include (or be connected to) an audio module and / or a display screen. In this case, the electronic device 200 may output the electrocardiogram (ECG) signal by voice broadcast through the audio module or by displaying the ECG signal through the display screen.

[0394] In other embodiments, the electronic device 200 outputs an electrocardiogram (ECG) signal, or it may send output information 2 to other electronic devices (such as electronic device 100). The output information 2 may include the ECG signal, and the output information 2 can be used by the receiving end to output the ECG signal.

[0395] In some embodiments, electronic device 200 (or electronic device 100) may output electrocardiogram (ECG) signals in one or more different forms, such as in the form of a waveform (outputting an ECG), or in the form of ECG indicators.

[0396] In some embodiments, electronic device 200 (or electronic device 100) can determine an electrocardiogram (ECG) based on an ECG signal and display the ECG on a display screen. The ECG can be a waveform diagram of the ECG signal, used to characterize the relationship between the amplitude of the ECG signal and time.

[0397] An electrocardiogram (ECG) can include several different waves, such as the P wave, QRS complex, T wave, and U wave. The following section describes the various waves in an ECG with reference to the ECG shown in Figure 5C.

[0398] As shown in Figure 5C, a two-dimensional coordinate system can include a horizontal axis and a vertical axis. The horizontal axis can represent time, and the vertical axis can represent voltage. The waveform of an electrocardiogram (ECG) signal within a single cardiac cycle can be represented by curve Q0 in this two-dimensional coordinate system.

[0399] As shown in Figure 5C, in curve Q0, the segment from time t1 to t2 can be called the P wave; the segment from time t2 to t3 can be called the QRS complex; the segment from time t3 to t4 can be called the T wave; and the segment from time t4 to t5 can be called the U wave. The point on curve Q0 at time t3 can be called the J point, which represents the end of the QRS complex. Furthermore, the time interval between time t1 and t2 can be called the PR interval, and the time interval between time t2 and t4 can be called the QT interval.

[0400] For example, the amplitude of curve Q0 changes as follows across different time periods: From time t0 to t1, the amplitude of curve Q0 remains stable; from time t1 to t2, the amplitude of curve Q0 first rises to the first peak, then decreases, and then returns to stability, showing a downward trend at time t2; from time t2 to t3, the amplitude of curve Q0 first decreases to the first trough, then rises, rises to the second peak, then decreases, decreases to the second trough, and then rises again; from time t3 to t4, the amplitude of curve Q0 gradually increases after a period of stability, rises to the third peak, and then gradually decreases to the third trough; from time t4 to t5, the amplitude of curve Q0 rises again from the third trough to the fourth peak, then decreases again, and then returns to stability. The amplitude at the second peak is significantly higher than the amplitudes at the other peaks.

[0401] It is understood that the embodiment shown in Figure 5C is only an example. In the embodiments of this application, the electrocardiogram may also include more cycles than the above embodiments, and the waveform in each cycle may also be different from the above embodiments. For example, in some cycles, the P wave may also include two peaks, etc. This application does not limit it here.

[0402] The waves and intervals on an electrocardiogram (ECG) can characterize the health of a user's heart. The P wave represents the depolarization process between the two atria. Because the sinoatrial node is located at the junction of the right atrium and the superior vena cava, excitation from the sinoatrial node is first conducted to the right atrium, then through the interatrial bundle to the left atrium, forming the P wave on the ECG. The P wave represents atrial excitation; the first half represents right atrial excitation, and the second half represents left atrial excitation. When the atria enlarge and conduction between the two atria becomes abnormal, the P wave appears as a tall, peaked or biphasic P wave. The PR interval represents the time from the start of atrial depolarization to the start of ventricular depolarization, mainly reflecting the time it takes for excitation to conduct through the atrioventricular junction. Slow conduction velocity at the atrioventricular node forms the PR segment on the ECG. When conduction from the atria to the ventricles is blocked, it manifests as a prolonged PR interval or the disappearance of the ventricular wave after the P wave. The QRS complex represents the ventricular depolarization process. When conduction block occurs in the left and right bundle branches of the heart, or when the heart is enlarged or hypertrophied, the QRS complex will widen, deform, and prolong its duration. The J point represents the completion of depolarization of all ventricular myocardial cells. The T wave represents two ventricular repolarization processes. Changes in the T wave on an electrocardiogram are influenced by various factors; for example, in myocardial ischemia, the T wave may be flattened and inverted, while a tall T wave can be seen in hyperkalemia, the hyperacute phase of acute myocardial infarction, etc. The U wave can be a waveform following the T wave and is currently believed to be related to ventricular repolarization. The QT interval represents the time required for the entire process of ventricular depolarization and repolarization. Prolongation of the QT interval is often associated with the occurrence of malignant arrhythmias.

[0403] Electronic device 200 can determine one or more electrocardiogram (ECG) parameters based on an ECG signal. Simultaneously with (or after) outputting the ECG signal, electronic device 200 can also output these one or more ECG parameters. ECG parameters may include, but are not limited to, any one or more of the following: heart rate, amplitude, PR interval, QT interval, and the duration of each wave (e.g., P wave duration). Heart rate can be determined based on the number of cardiac cycles per minute in the ECG signal. The PR interval, QT interval, and P wave duration can all be determined based on the ECG (or ECG signal).

[0404] Figure 6 shows a flowchart of another measurement method provided in an embodiment of this application.

[0405] As shown in Figure 6, the specific procedure of the measurement method may include the following steps:

[0406] S601. Electronic device 100 determines that monitoring condition 3 is met and sends information 3 to electronic device 200. Information 3 is used to request electronic device 200 to send physiological data 1 to electronic device 100.

[0407] In some embodiments, monitoring condition 3 may include, but is not limited to, any one or more of the following: receiving an operation from the user to enable the physiological monitoring function, receiving a start command 1 sent by another electronic device, detecting abnormal physiological state of the user (e.g., heart rate not belonging to a preset heart rate range), detecting abnormal psychological state of the user (e.g., being startled), detecting that the user is in a state of exercise, detecting that the user is insomnia, detecting abnormal body posture of the user (e.g., falling), detecting abnormal sports equipment of the user, detecting that the user's location is within a preset area (e.g., the user is in a high-altitude area), etc.

[0409] Physiological data 1 may include, but is not limited to, any one or more of the following: current data, body temperature, measured value of physiological parameter 1, calibrated value of physiological parameter 1, etc. Among them, current data is used to characterize the magnitude of the reaction current generated when the electrochemical electrode in electronic device 200 reacts with target substance 1. Body temperature may be the body temperature of the user (or other biological entity) wearing electronic device 200. The measured value of physiological parameter 1 may be the value of physiological parameter 1 determined by electronic device 200 based on current data through a calculation model of physiological parameter 1. The calibrated value of physiological parameter 1 may be the value of physiological parameter 1 determined by electronic device 200 based on current data and body temperature, that is, the value of physiological parameter 1 after calibration based on body temperature.

[0410] The following describes the specific method by which electronic device 100 determines whether monitoring condition 3 is met.

[0411] In some embodiments, the electronic device 100 can acquire user information and determine whether the electronic device 100 meets monitoring condition 3 based on the user information. The user information may include, but is not limited to, any one or more of the following: physiological information, psychological information, motion information, sports equipment information, posture information, location information, and interaction information. Physiological information can be used to characterize the user's physiological state, including but not limited to one or more of the following: heart rate, body temperature, blood pressure, disease information, etc.; psychological information can be used to characterize the user's psychological state, including but not limited to one or more of the following: stress level, low mood, stable mood, high mood, being startled, etc.; exercise information can be used to characterize the user's exercise state, including but not limited to one or more of the following: swimming, diving, cycling, running, mountain climbing, rope skipping, yoga, etc.; exercise equipment information can be used to characterize the status of exercise equipment, including but not limited to one or more of the following: remaining oxygen in oxygen cylinders, weight of smart backpacks, resistance of bicycles, etc.; posture information can be used to characterize the user's body posture, including but not limited to one or more of the following: falling, misstepping, remaining still, etc.; location information can be used to characterize the user's location, including but not limited to one or more of the following: the user's geographical location, the latitude and longitude of the user's location, the altitude of the user's location, the depth of the user's location, etc.; interaction information can include the user's interaction with the electronic device 100, such as receiving the user's action to activate the physiological monitoring function, etc.

[0415] It is understood that the embodiments described herein are merely examples. In the embodiments of this application, the electronic device 100 may include more, fewer, or different devices than those described in the above embodiments. Furthermore, the electronic device 100 may also collect user information through sensors or other devices different from those described in the above embodiments. This application does not impose any limitations on these embodiments.

[0416] The following describes some methods by which electronic devices 100, based on user information, determine whether monitoring condition 3 is met, according to embodiments of this application.

[0417] If the electronic device 100 determines that any physiological information is abnormal, then it determines that the monitoring conditions are met. For example, abnormal physiological information may include, but is not limited to, any one or more of the following: heart rate not falling within a preset heart rate range, blood pressure not falling within a preset blood pressure range, body temperature not falling within a preset body temperature range, etc.

In this application embodiment, the electronic device 100 may also determine whether monitoring condition 3 is met based on various types of user information, and the electronic device 100 may also determine whether monitoring condition 3 is met based on other information in the user information. Furthermore, monitoring condition 3 may include more, fewer, or different conditions than those in the above embodiments, and this application does not limit these conditions.

[0424] S602. Electronic device 200 acquires physiological data 1.

[0425] In some embodiments, electronic device 200 may, in response to information 3, begin acquiring physiological data 1.

[0426] In other embodiments, the electronic device 200 may also periodically acquire physiological data 1 before receiving information 3.

[0427] The method by which electronic device 200 acquires physiological data 1 can be referred to the relevant content of step S501 shown in Figure 5A above, and will not be repeated here.

[0428] S603. Electronic device 200 sends physiological data 1 to electronic device 100.

[0429] In some embodiments, electronic device 200 may send physiological data 1 to electronic device 100 in response to information 3.

[0430] In some embodiments, the electronic device 200 periodically sends physiological data 1 to the electronic device 100 before receiving information 3. In this case, step S602 described above may not be performed; furthermore, monitoring condition 3 may be used to trigger the electronic device 100 to perform step S605 described below.

[0431] S604. Electronic device 100 determines physiological parameters 1 based on physiological data 1.

[0432] In some embodiments, if physiological data 1 includes a measured or calibrated value of physiological parameter 1, the electronic device 100 may use the measured or calibrated value of physiological parameter 1 as the value of physiological parameter 1.

[0433] In some embodiments, if physiological parameter 1 includes the measured value of physiological parameter 1 and body temperature, the electronic device 100 can calibrate the measured value of physiological parameter 1 based on body temperature and determine the calibrated value as the value of physiological parameter 1.

[0434] In some embodiments, if physiological data 1 includes current data, the electronic device 100 can determine the value of physiological parameter 1 based on the current data. Optionally, if physiological data 1 also includes body temperature, the electronic device 100 can also determine the value of physiological parameter 1 based on both current data and body temperature.

[0435] S605. Electronic device 100 outputs physiological parameter 1.

The electronic device 100 may output physiological parameter 1 in the following ways, including but not limited to any one or more of the following: display screen display, voice broadcast, vibration, indicator light flashing, etc. A schematic diagram of the interface through which the electronic device 100 outputs physiological parameter 1 can be found in the relevant descriptions of the embodiments shown in Figures 7C to 7F below, which will not be detailed here.

[0437] In some embodiments, the electronic device 100 may output one or more of the following while outputting the user's physiological parameter 1 (or after outputting physiological parameter 1): assessment result, value range, user status, historical curve, and reference suggestions. The assessment result characterizes whether the user's physiological parameter is normal. The value range refers to the normal range of the user's physiological parameter. The user status refers to the user's current state, such as fasting, non-fasting, exercise, high altitude, or sleep. The historical curve characterizes the relationship between the physiological parameter and time over a past period (e.g., 30 minutes, 3 hours, 24 hours). The reference suggestions can be used to guide the user to maintain or restore the physiological parameter to the normal range.

[0438] In other embodiments, after determining the user's physiological parameter 1, the electronic device 100 may also send an output instruction to other electronic devices. The output instruction may include the user's physiological parameter 1 and can be used to instruct the electronic device to output the user's physiological parameter 1. Optionally, the output instruction may also include, but is not limited to, any one or more of the following: user status, value range, evaluation result, historical curve, reference suggestions, etc. The electronic device 100 may output any one or more of the above content based on the output instruction.

[0439] The following sections describe how the evaluation results, value ranges, user status, historical curves, and reference suggestions were determined.

[0440] The following describes how user status is determined.

[0441] In some embodiments, the electronic device 100 can determine the user's state based on user information. The specific content of the user information can be found in the relevant description in step S501 above, and will not be repeated here. For example, the electronic device 100 can receive and respond to the user's operation of setting the user's state to determine the user's state. Another example is that the electronic device 100 can determine whether the user is in motion based on the user's motion information. Yet another example is that the electronic device 100 can determine whether the user is at a high altitude based on the user's location information, etc. It is understood that the embodiments described here are merely illustrative of how the electronic device 100 can determine the user's state based on user information. In this application embodiment, the electronic device 100 can also determine the user's state based on other information in the user information, and this application does not limit this.

[0442] The following describes how to determine the value range.

[0443] The value range can be the range of values ​​for the physiological parameter stored in the electronic device 100. For example, Table 1 shows the value range of a physiological parameter stored in an electronic device 100 according to an embodiment of this application.

[0444] Table 1

[0445] As shown in Table 1, the electronic device 100 can store value ranges for one or more physiological parameters. For example, the value range for blood glucose can be [3.9, 6.1], the value range for blood ketones can be [0.05, 0.3], and the value range for uric acid can be [0.18, 0.42]. The unit for the above value ranges is millimoles per liter (mmol / L).

[0446] It is understood that the embodiments shown in Table 1 are only examples. In the embodiments of this application, the electronic device 100 may also store more, fewer or different ranges of physiological parameters than those shown in Table 1, and the ranges of physiological parameters may also be different from those described above. This application does not limit this.

[0447] In other embodiments, the electronic device 100 may also store the value ranges of physiological parameters under different user states. For example, Table 2 shows the value ranges of physiological parameters under different user states stored by another electronic device 100 provided in this application embodiment.

[0448] Table 2

[0449] As shown in Table 2, the electronic device 100 can store the value ranges of one or more physiological parameters under different user states. For example, in a fasting state, the blood glucose value range can be [3.9, 6.1]; in a non-fasting state, the blood glucose value range can be [3.9, 8.99]; in a fasting state, the blood ketone value range can be [0.05, 0.3]; in a non-fasting state, the blood ketone value range can be [0.05, 0.5]; in a fasting state, the uric acid value range can be [0.18, 0.42]; in a non-fasting state, the uric acid value range can be [0.18, 0.5]. The unit of the above value ranges is millimoles per liter (mmol / L).

[0450] It is understood that the embodiments shown in Table 2 are merely examples. In the embodiments of this application, the electronic device 100 may also store more, fewer, or different ranges of physiological parameters than those shown in Table 2, and the ranges of physiological parameters may also differ from those described above. This application does not impose any limitations on these ranges. Furthermore, the user status may also include more, fewer, or different user statuses than those described in the above embodiments. Moreover, in some embodiments, the electronic device 100 may also store the correspondence between factors such as user gender, age, and disease and the ranges of values. This application does not impose any limitations on these ranges.

[0451] Electronic device 100 can determine the value range based on one or more factors such as user status, user age, and gender.

[0452] The following describes how the evaluation results are determined.

[0453] In one possible implementation, the electronic device 100 can store the value ranges of the user's physiological parameters and determine the evaluation result based on the user's physiological parameter 1 and the corresponding value range of the physiological parameter. In another possible implementation, the electronic device 100 can also determine the value range of the user's current physiological parameters based on the correspondence between the user's gender, age, user status, or one or more factors and the value range, and determine the evaluation result based on the calibration value of the physiological parameters.

[0454] In some embodiments, the evaluation result may include normal and abnormal. When physiological parameter 1 falls within the range, the electronic device 100 can determine that the evaluation result is normal. When physiological parameter 1 does not fall within the range, the electronic device 100 can determine that the evaluation result is abnormal. Optionally, in the case of an abnormal evaluation result, the evaluation result may be further subdivided into any one or more of the following: too high, too low, too high, too low, etc., which are not limited herein.

[0455] In some embodiments, if the evaluation result is determined to be abnormal (or the evaluation result is determined to be abnormal, such as too high or too low), the electronic device 100 may output a warning. The warning output method may include, but is not limited to, any one or more of the following: display screen display, voice broadcast, vibration, indicator light flashing, etc.

[0456] The following describes how historical curves are determined.

[0457] In some embodiments, the electronic device 100 can determine the historical curve of a physiological parameter based on the calibration value of the physiological parameter measured in the current measurement. In other embodiments, the electronic device 100 can also determine the historical curve of the physiological parameter based on the calibration value of the physiological parameter measured in the current measurement and previously measured calibration values ​​of the physiological parameter. The electronic device 100 can store the measurement time of each physiological parameter calibration value, and the electronic device 100 can determine the historical curve of the physiological parameter based on the different calibration values ​​corresponding to different measurement times.

[0458] The following describes how to determine the reference recommendations.

[0459] In one possible implementation, the electronic device 100 can determine reference suggestions based on the assessment results. For example, if the assessment result is normal, the reference suggestions could be to advise the user to maintain their current lifestyle, or to advise the user to increase exercise and maintain a good sleep schedule, etc. If the assessment result is abnormal, the reference suggestions could be to advise the user to correct bad lifestyle habits, reduce the intake of greasy food, etc.

[0460] In another possible implementation, the electronic device 100 can also determine reference suggestions based on user information. For example, when the electronic device 100 determines that the user is in a high-altitude area based on user information, the reference suggestion may include "The oxygen is thin in the current area, so be careful to reduce strenuous exercise." As another example, when the electronic device 100 determines that the user has been in a fasting state for a duration exceeding a certain period (e.g., 4 hours), the reference suggestion may include "You are currently hungry, please eat as soon as possible," etc. It is understood that the embodiments described here are merely illustrative of how the electronic device 100 can determine reference suggestions based on user information. In this application embodiment, the electronic device 100 may also determine content different from the above reference suggestions based on user information, which is not limited herein.

[0461] S606. Electronic device 100 determines that monitoring condition 4 is met and sends information 4 to electronic device 200. Information 4 is used to request electronic device 200 to send an electrocardiogram signal to electronic device 100.

[0462] In some embodiments, monitoring condition 4 may include, but is not limited to, any one or more of the following: receiving an operation from the user to activate the ECG function, receiving a start command 2 from another electronic device, detecting abnormal physiological state of the user (e.g., blood glucose not falling within a preset blood glucose range), detecting abnormal psychological state of the user (e.g., being startled), detecting that the user is in motion, detecting that the user is insomnia, detecting abnormal body posture of the user (e.g., falling), detecting abnormal sports equipment of the user, detecting that the user's location is within a preset area (e.g., the user is in a high-altitude area), etc.

[0463] The determination method for each condition in monitoring condition 4 can also refer to the relevant content in step S601 above, and will not be repeated here.

[0464] In some other embodiments, monitoring condition 4 may be the same as monitoring condition 3, that is, when electronic device 100 determines that monitoring condition 3 is met, electronic device 100 may execute the above step S602 and the following step S608.

[0465] S607. Electronic device 200 acquires electrocardiogram (ECG) signals.

[0466] In some embodiments, the electronic device 200 may, in response to information 4, begin acquiring electrocardiogram (ECG) signals.

[0467] In other embodiments, the electronic device 200 may also periodically acquire electrocardiogram signals before receiving information 4.

[0468] The method by which electronic device 200 acquires electrocardiogram signals can be referred to the relevant content of step S503 shown in Figure 5A above, and will not be repeated here.

[0469] S608. Electronic device 200 sends an electrocardiogram signal to electronic device 100.

[0470] In some embodiments, electronic device 200 may send an electrocardiogram signal to electronic device 100 in response to information 4.

[0471] In some embodiments, electronic device 200 periodically sends electrocardiogram (ECG) signals to electronic device 100 before receiving information 4. In this case, step S608 described above may not be performed; furthermore, in this case, monitoring condition 4 may be used to trigger electronic device 100 to perform step S609 as described below.

[0472] S609. Electronic device 100 outputs electrocardiogram (ECG) signal.

[0473] The electronic device 100 can output electrocardiogram signals in one or more ways, such as display screen, audio broadcast, vibration, and indicator light flashing.

[0474] The electronic device 100 can also output electrocardiogram (ECG) signals. Optionally, after outputting the ECG (or simultaneously with outputting the ECG), the electronic device 100 can also output one or more of the following: one or more ECG indicators, the evaluation results of the ECG indicators, the evaluation results of ECG function, the value range of the ECG indicators, and the user's status. The value range of the ECG indicator refers to the normal range of the ECG indicator. The user status refers to the user's current state, such as resting state, exercise state, high altitude state, sleep state, etc. The evaluation results of the ECG indicator are used to indicate whether the ECG indicator belongs to the preset value range of the ECG indicator. The evaluation results of ECG function are used to indicate whether the user's heart function is normal.

[0475] The specific content and determination method of the ECG indicators can be referred to the relevant description in step S504 shown in Figure 5A above; the value range of the ECG indicators can be pre-stored by the electronic device 100; the evaluation result of the ECG indicators can be determined based on the ECG indicators and the value range of the ECG indicators, and the specific method can be referred to the relevant description in step S605 above; the evaluation result of the ECG function can be determined based on the evaluation result of one or more ECG indicators; the method of determining the user status can also refer to the relevant description in step S605 above, and will not be repeated here.

[0476] In some application scenarios, physiological parameter 1 can be blood glucose, and the output interface diagram of blood glucose can be referred to in Figures 7A-7F below.

[0477] For example, as shown in Figure 7A, the electronic device 100 displays a health application interface 700, which may include one or more items, such as blood glucose item 701, blood pressure item, electrocardiogram item 702, blood oxygen item, etc. Each item can be used to trigger the electronic device 100 to display the corresponding physiological parameter monitoring interface.

[0478] The electronic device 100 can receive and respond to the user's click operation on the blood glucose entry 701, and display the blood glucose monitoring interface 710 as shown in Figure 7B.

[0479] As shown in Figure 7B, the blood glucose monitoring interface 710 may include a measurement control 711 and a history control 712. The measurement control 711 can be used to trigger the electronic device 100 to determine and output the user's blood glucose, and the history control 712 is used to trigger the electronic device 100 to display past blood glucose measurement records (including measurement time and the user's blood glucose).

[0480] Electronic device 100 can receive and respond to the user's click operation on the measurement control 711. After determining the user's blood glucose based on the physiological data sent by electronic device 200, electronic device 100 can display the output interface 720 as shown in Figure 7C.

[0481] As shown in Figure 7C, the output interface 720 may include a blood glucose level 721, which indicates the user's blood glucose value. Optionally, the output interface 720 may also include, but is not limited to, any one or more of the following: an evaluation result 722, a value range 723, a user status 724, and a historical curve control 725. The evaluation result 722 can be used to indicate whether the user's blood glucose is normal. As shown in Figure 7C, the evaluation result 722 is a horizontal line, which can represent that the user's blood glucose value belongs to a preset value range, i.e., the user's blood glucose is normal. In some embodiments, if the user's blood glucose value is greater than the preset value range, the evaluation result can also be an upward arrow; if the user's blood glucose value is less than the preset value range, the evaluation result can also be a downward arrow. It is understood that the display method of the evaluation result 722 shown in Figure 7C is only an example. In the embodiments of this application, the evaluation result can also be represented by different symbols, text, etc., and this application does not limit this. The value range 723 is used to represent the reference range of the user's blood glucose, i.e., the normal value range of the user's blood glucose in the current user state. The user status 724 can be used to indicate the user's current state, for example, a fasting state. In some embodiments, the value range 723 may differ depending on the user's state. The historical curve control 725 can be used to trigger the electronic device 100 to display a historical blood glucose curve, which represents the relationship between the user's blood glucose value and time over a past period.

[0482] The electronic device 100 can receive and respond to a user's click operation on the historical curve control 725, and display the historical curve interface 730 as shown in Figure 7D. Alternatively, the electronic device 100 can also receive and respond to a user's swipe-up operation on the output interface 720, and display the historical curve and other content as shown in Figure 7D on the output interface 720.

[0483] As shown in Figure 7D, the historical curve interface 730 may include a historical curve 731, and optionally, may also include reference suggestions 732. The historical curve 731 can be used to characterize the relationship between a user's blood glucose levels and time over a past period. The reference suggestions 732 can be used to guide the user to maintain or restore blood glucose levels to a normal range. For example, the reference suggestions 732 may include the text "Stable blood glucose, please maintain." It is understood that the reference suggestions 732 shown in Figure 7D are only an example. In this embodiment, the reference suggestions 732 may also adopt a different output format than the above embodiments, and may include more, less, or different content than the above embodiments. This application does not limit this.

[0484] In other embodiments, the electronic device 100 may receive and respond to a user's click operation on the measurement control 711. After determining the user's blood glucose (i.e., blood glucose value) based on physiological data, if the user's blood glucose is abnormal, the electronic device 100 may optionally display a warning interface 740 as shown in FIG7E, or display an output interface 750 as shown in FIG7F.

[0485] As shown in Figure 7E, the warning interface 740 may include a warning 741, and optionally, a result viewing control 742. The warning 741 can be used to alert the user to an abnormal blood glucose level. For example, the warning 741 may include the text "Blood glucose too low, please eat as soon as possible!!". The result viewing control 742 can be used to trigger the electronic device 100 to display the blood glucose value.

[0486] The electronic device 100 can receive and respond to a user's click operation on the viewing results control 742, and display the output interface 750 as shown in FIG7F. In some embodiments, the electronic device 100 can also display the output interface 750 as shown in FIG7F when it detects that the display duration of the warning interface 740 is longer than a preset duration (e.g., 10 seconds, 15 seconds, etc.).

[0487] As shown in Figure 7F, the output interface 750 may include a blood glucose level 751, which can be the user's blood glucose value. Optionally, the output interface 750 may also include, but is not limited to, any one or more of the following: assessment result 752, value range 753, user status 754, and reference suggestion 755. The assessment result 752 can be used to indicate whether the user's blood glucose is normal. As shown in Figure 7F, the assessment result 752 is a downward arrow, which can indicate that the user's blood glucose value is less than a preset value range, i.e., the user's blood glucose is abnormal. The value range 753 is used to represent the user's blood glucose reference range, i.e., the range of blood glucose values ​​when the user is in a healthy state. The user status 754 can be used to indicate the user's current status, for example, a fasting state. In some embodiments, the value range 753 may also be different depending on the user status. The output interface 750 may also include reference suggestion 755, for example, reference suggestion 755 may include the text "Blood glucose is too low, please eat as soon as possible!". It is understood that in some other embodiments, the output interface 750 may also display a historical blood glucose curve (or a historical curve control), which is used to characterize the relationship between the user's blood glucose value and time over a period of time. This application does not limit this.

[0488] It is understood that the embodiments shown in Figures 7A to 7F above are only two examples. In the embodiments of this application, the output physiological parameters may also be other physiological parameters (such as blood ketones, uric acid, etc.), the device for outputting physiological parameters may also be electronic device 200 or other electronic devices, and the content displayed in the output interface may include more, less or different content than the above embodiments. This application does not limit these contents here.

[0489] Figures 7G-7J show schematic diagrams of a set of electrocardiogram (ECG) signal output interfaces provided in embodiments of this application.

[0490] For example, as shown in Figure 7G, the electronic device 100 may display a health application interface 700, which may include one or more items, such as blood glucose item 701, blood pressure item, electrocardiogram item 702, blood oxygen item, etc. Each item can be used to trigger the electronic device 100 to display the corresponding physiological parameter monitoring interface.

[0491] The electronic device 100 can receive and respond to the user's click operation on the ECG entry 702 and display the ECG monitoring interface 760 as shown in Figure 7H.

[0492] As shown in Figure 7H, the ECG monitoring interface 760 may include a measurement control 761 and a history control 762. The measurement control 761 can be used to trigger the electronic device 100 to determine and output the user's ECG signal, and the history control 762 is used to trigger the electronic device 100 to display past ECG signal measurement records.

[0493] Electronic device 100 can receive and respond to the user's click operation on measurement control 761. After determining the user's electrocardiogram based on the electrocardiogram signal sent by electronic device 200, electronic device 100 can display the output interface 770 as shown in FIG7I.

[0494] As shown in Figure 7I, the output interface 770 may include an electrocardiogram 771, which may be a waveform diagram of an electrocardiogram signal.

[0495] In some embodiments, the electronic device 100 can also receive and respond to a user's swipe-up operation on the output interface 770. As shown in FIG7J, the electronic device 100 can display one or more of the following contents on the output interface 770: heart rate 772, heart rate assessment result 773, amplitude 774, amplitude assessment result 775, and user status 776, etc. Here, heart rate 772 is used to indicate the user's heart rate; heart rate assessment result 773 is used to indicate whether the user's heart rate is normal; amplitude 774 is used to indicate the amplitude of the electrocardiogram signal; amplitude assessment result 775 is used to indicate whether the amplitude of the electrocardiogram signal is normal; user status 776 is used to indicate the user's current status, such as resting state (or exercise state, etc.), and the user status may have a certain impact on the electrocardiogram signal. As shown in FIG7J, heart rate assessment result 773 and amplitude assessment result 775 are both horizontal lines, which can indicate that the user's electrocardiogram belongs to a preset value range, that is, the user's electrocardiogram is normal. Other specific details of heart rate assessment result 773 and amplitude assessment result 775 can be found in the relevant content of assessment result 722 in the embodiment shown in Figure 7C above, and will not be repeated here.

[0496] It is understood that the embodiments shown in Figures 7G-7J above are only examples. In the embodiments of this application, the output interface of the electrocardiogram signal may also include more, less or different content than the above embodiments, such as electrocardiogram indicators such as P wave duration and QT interval. This application does not limit this.

[0497] In some application scenarios, electronic device 100 can also prompt the user to perform electrocardiogram monitoring when it detects an abnormal value of physiological parameter 1.

[0498] For example, taking physiological parameter 1 as blood glucose, Figure 7K shows the prompt interface 780 of electronic device 100 when blood glucose is abnormal.

[0499] As shown in Figure 7K, the prompt interface 780 may include a prompt 781, an agreement control 782, and a rejection control 783. The prompt 781 can be used to prompt the user to perform ECG monitoring. The prompt 781 may include text, such as "Abnormal blood sugar detected; it is recommended to enable the ECG monitoring function." The agreement control 782 can be used to trigger electronic device 100 to send information 4 to electronic device 200, requesting electronic device 200 to send an ECG signal to electronic device 100. Optionally, the agreement control 782 may also display a countdown (e.g., 5 seconds, 3 seconds, etc.). When the countdown ends and electronic device 100 has not received the user's operation, electronic device 100 may send information 4 to electronic device 200. The rejection control 783 can be used to trigger electronic device 100 to stop displaying the prompt interface 780. Optionally, it may also trigger electronic device 100 to output blood sugar calibration values, etc.

[0500] Electronic device 100 can receive and respond to a user's click on the consent control 782, displaying an ECG monitoring interface 790 as shown in FIG7L. The ECG monitoring interface 790 is used to notify the user that electronic device 100 is acquiring ECG signals. In some embodiments, after receiving an ECG signal from electronic device 200, electronic device 100 can display an output interface 770 as shown in FIG7I above.

[0501] It is understood that Figures 7K-7L above are merely illustrative examples. When the value of physiological parameter 1 is abnormal, it can trigger a prompt to the user to turn on ECG monitoring. In this embodiment of the application, the electronic device 100 can also directly jump to the ECG monitoring interface when it detects that the value of physiological parameter 1 (such as blood glucose, blood ketones, etc.) is abnormal, and display the ECG signal after obtaining the ECG signal. This application does not limit this.

[0502] In other application scenarios, the electronic device 100 can have a micro-physical examination function. When the electronic device 100 detects that the user has enabled the micro-physical examination function, it can output one or more physiological parameters and electrocardiogram signals after determining a variety of physiological parameters and electrocardiogram signals.

[0503] For example, as shown in Figure 7M, the electronic device 100 can display a micro-health check interface 800. The micro-health check interface 800 may include a health check control 801, which can be used to trigger the electronic device 100 to output one or more physiological parameters and electrocardiogram (ECG) signals. Optionally, the micro-health check interface 800 may also display health check items, which can be used to prompt the user about the items that the micro-health check function can monitor. For example, in the embodiment shown in Figure 7M, the health check items may include ECG, blood glucose, and blood ketones. After the micro-health check function is enabled, the electronic device 100 can output ECG, blood glucose, and blood ketones, etc.

[0504] Optionally, before displaying the micro-health check interface 800, the electronic device 100 may also display an interface where the user can select health check items. The electronic device 100 can receive and respond to the user's operation of selecting health check items and display the micro-health check interface 800 as shown in Figure 7M.

[0505] The electronic device 100 can receive and respond to user clicks on the health check control 801. After determining the blood glucose, blood ketone, and electrocardiogram (ECG) signals, the electronic device 100 can display the output interface 810 as shown in Figure 7N. The output interface 810 may include an ECG 811, and may also include blood glucose values ​​812 and blood ketone values ​​813. Optionally, the output interface 810 may also include, but is not limited to, any one or more of the following: ECG indicators, blood glucose value range, blood ketone value range, blood glucose assessment results, and blood ketone assessment results.

[0506] It is understood that the embodiments shown in Figures 7M-7N are merely illustrative examples. The electronic device 100 can simultaneously output one or more physiological parameters and electrocardiogram signals. In the embodiments of this application, the items monitored by the micro-physical examination function may also be different from those in the above embodiments. The electronic device 100 may also simultaneously output multiple physiological parameters. This application does not limit this.

[0507] The functional modules of an electronic device 200 provided in the embodiments of this application are described below.

[0508] Figure 8 shows a schematic diagram of the functional modules of a measurement system 10 provided in an embodiment of this application.

In some embodiments, the communication module 2004 can receive and respond to information 1 sent by other electronic devices (e.g., electronic device 100), and send the message N1 to the electrochemical module 2001, whereby message N1 instructs the electrochemical module 2001 to begin acquiring current data of one or more physiological parameters specified by message N1. The communication module 2004 can also receive and respond to information 2 sent by other electronic devices (e.g., electronic device 100), and send the message N2 to the electrocardiogram module 2002, whereby message N2 instructs the electrocardiogram module 2002 to begin acquiring electrocardiogram signals. In other embodiments, the communication module 2004 can also receive information 1 sent by other electronic devices (e.g., electronic device 100) and send information 1 to the control module 2006. The communication module 2004 can also receive information 2 sent by other electronic devices (e.g., electronic device 100) and send information 2 to the control module 2006.

[0514] The control module 2006 can also determine whether monitoring condition 1 or monitoring condition 2 is met. When monitoring condition 1 is met, the control module 2006 can send message N1 to the electrochemical module 2001, which instructs the electrochemical module 2001 to begin acquiring current data of one or more physiological parameters specified in message N1. When monitoring condition 2 is met, the control module 2006 can send message N2 to the electrochemical module 2001, which instructs the electrocardiogram module 2002 to begin acquiring electrocardiogram signals. In some embodiments, monitoring condition 1 may include receiving information 1 sent by the communication module 2004, and monitoring condition 2 may include receiving information 2 sent by the communication module 2004.

[0517] It is understood that the embodiment shown in Figure 8 is only an example. In the embodiments of this application, the electronic device 200 may also include more, fewer or different functional modules than the above embodiments, or combine the above multiple functional modules into one functional module, or split any of the above functional modules into multiple functional modules. This application does not limit this.

[0518] The functional modules of a measurement system 10 provided in the embodiments of this application are described below.

[0519] Figure 9 shows a schematic diagram of the functional modules of a measurement system 10 provided in an embodiment of this application.

[0520] As shown in Figure 9, the measurement system 10 may include electronic device 100 and electronic device 200.

Optionally, electronic device 200 may also include any one or more of the following: a temperature module 2005, a control module 2006, etc. Wherein:

[0521] The interaction module 1001 can receive and respond to user operations, such as activating the physiological monitoring function or activating the electrocardiogram (ECG) function. In response to the user's activation of the physiological monitoring function, the interaction module 1001 can send message N3 to the communication module 1002. Message N3 can instruct the communication module 1002 to send information 3 to the electronic device 200, whereby information 3 requests physiological data for one or more specified physiological parameters.

[0522] The communication module 1002 can communicate with other electronic devices (such as electronic device 200). In some embodiments, the communication module 1002 can receive and respond to message N3, sending information 3 to the communication module 2004 in electronic device 200, whereby information 3 requests physiological data. The communication module 1002 can also receive physiological data sent by the communication module 2004 in electronic device 200 and send the physiological data to the data processing module 1003. In some embodiments, the communication module 1002 can also receive physiological parameters (i.e., values ​​of physiological parameters) sent by the data processing module 1003, and receive evaluation results and / or reference suggestions sent by the evaluation module 1005, and send one or more of the physiological parameters, evaluation results, and reference suggestions to other electronic devices.

[0523] The data processing module 1003 can determine physiological parameters, such as blood glucose and blood ketones, based on the physiological data sent by the communication module 1002. After determining the physiological parameters, the data processing module 1003 can send the physiological parameters to the output module 1006 or the communication module 1002. In some embodiments, the data processing module 1003 can also send the physiological parameters to the evaluation module 1005.

[0524] User information module 1004 can acquire user information. In some embodiments, user information module 1004 can collect user information; in other embodiments, user information module 1004 can receive user information acquired by communication module 1002 from other electronic devices.

In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. These logical relationships of hardware circuits are fixed or reconfigurable. For example, the processor is a hardware circuit implemented as an ASIC or PLD, such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units. Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a Neural Network Processing Unit (NPU), Tensor Processing Unit (TPU), or Deep Learning Processing Unit (DPU).

[0557] Figure 11 shows a flowchart of a measurement method provided in an embodiment of this application.

[0558] As shown in Figure 11, the specific procedure of the measurement method may include the following steps:

[0559] S1101.

[0560] The first electronic device may be the electronic device 200 in the above embodiments. The first electrode group may be the electrode group 1 in the above embodiments, and the second electrode group may be the electrode group 2 in the above embodiments.

[0561] The first distance can be a preset distance, such as three centimeters. When the distance between the first electrode group and the second electrode group is greater than the first distance, the first electrode group and the second electrode group can measure electrocardiogram signals.

[0562] In one possible implementation, the first physiological parameter may include, but is not limited to, any one or more of the following: blood glucose, blood ketones, uric acid, blood lactate, etc.

[0563] The specific method by which the first electronic device determines the first physiological parameter through the first electrode group can be referred to the relevant description in the embodiment shown in Figure 5A above, and will not be repeated here.

[0564] In one possible implementation, the first electrode group includes a first working electrode and a first pair of electrodes, and the second electrode group includes a second working electrode; the first pair of electrodes forms a circuit with the first working electrode; determining a first physiological parameter through the first electrode group specifically includes: determining the first physiological parameter through the first working electrode and the first pair of electrodes; determining an electrocardiogram (ECG) signal through the first electrode group and the second electrode group specifically includes: determining the ECG signal through the first working electrode and the second working electrode, or, determining the ECG signal through the first pair of electrodes and the second working electrode.

[0565] In this way, the first electrode group can form a two-electrode system through which the first physiological parameter can be measured. The first working electrode (or the first pair of electrodes) in the first electrode group and any one electrode in the second electrode group can be used as the LA electrode and RA electrode, respectively, to measure the electrocardiogram signal.

[0566] In one possible implementation, the first electrode group includes a first working electrode and a first pair of electrodes, and the second electrode group includes a second working electrode; the first pair of electrodes forms a circuit with the first working electrode; the first working electrode or the first pair of electrodes is connected to the right leg drive circuit; determining a first physiological parameter through the first electrode group specifically includes: determining the first physiological parameter through the first working electrode and the first pair of electrodes; determining an electrocardiogram signal through the first electrode group and the second electrode group specifically includes: determining the electrocardiogram signal through the first working electrode, the first pair of electrodes, and the second working electrode.

The specific circuit composition of the right leg drive circuit can be found in the relevant content of the embodiments shown in Figure 4C above, and will not be repeated here.

[0568] In this way, the first electrode group can form a two-electrode system through which the first physiological parameter can be measured. The first working electrode, the first pair of electrodes in the first electrode group, and any one of the electrodes in the second electrode group can be used as the LA electrode, RLD electrode, and RA electrode, respectively, to measure the electrocardiogram signal.

[0569] In one possible implementation, the first electrode group includes a first working electrode, a first reference electrode, and a first pair of electrodes; the first reference electrode is used to control the voltage of the first working electrode, and the first pair of electrodes forms a circuit with the first working electrode; determining a first physiological parameter through the first electrode group specifically includes: generating a first current through the first working electrode; and determining the first physiological parameter based on the first current.

[0570] In this way, the first electrode group can form a three-electrode system, through which the first current is generated and conducted.

[0572] In this way, the second electrode group can form a three-electrode system, through which a second current is generated and conducted.

[0575] In one possible implementation, the electrocardiogram (ECG) signal is determined by a first electrode group and a second electrode group, specifically by determining the ECG signal by any one electrode in the first electrode group and any one electrode in the second electrode group.

[0576] The left and right arm electrodes can be selected from one electrode in the first electrode group and one electrode in the second electrode group, respectively. In this way, electrocardiogram signals can be measured using the left and right arm electrodes.

[0577] In one possible implementation, the electrocardiogram (ECG) signal is determined by a first electrode group and a second electrode group, specifically including: determining the ECG signal by any two electrodes in the first electrode group and any one electrode in the second electrode group; or, determining the ECG signal by any two electrodes in the first electrode group and any two electrodes in the second electrode group.

[0578] The left arm electrode and right arm electrode can be selected from one electrode in the first electrode group and one electrode in the second electrode group, respectively. The right leg drive electrode can be an electrode from either the first electrode group or the second electrode group. In this way, electrocardiogram (ECG) signals can be measured using the left arm electrode, right arm electrode, and right leg drive electrode. The right leg drive electrode is used to cancel common-mode signals through the right leg drive circuit.

[0579] In this way, the electrochemical electrodes in the first electrode group can be used to measure both the first physiological parameter and the electrocardiogram signal.

[0580] In one possible implementation, the electrocardiogram (ECG) signal is determined by any two electrodes in the first electrode group and any one electrode in the second electrode group. Specifically, when the first pair of electrodes is connected to the right leg drive circuit, the ECG signal is determined by the first pair of electrodes, the first working electrode, and the second reference electrode.

[0581] In one possible implementation, the electrocardiogram (ECG) signal is determined by any one electrode in the first electrode group and any two electrodes in the second electrode group. Specifically, when the second pair of electrodes is connected to the right leg drive circuit, the ECG signal is determined by the second pair of electrodes, the second working electrode, and the first reference electrode.

[0582] It should be noted that the above two implementation methods are just two examples. In this application, other electrodes in the first electrode group and the second electrode group can also be selected to measure electrocardiogram signals. This application does not limit this.

[0583] In one possible implementation, the first electrode group further includes a first ECG electrode and a second ECG electrode, and the second electrode group further includes a third ECG electrode. The second ECG electrode is connected to a right leg drive circuit. The ECG signal is determined by the first electrode group and the second electrode group, specifically by determining the ECG signal through the first ECG electrode, the second ECG electrode, and the third ECG electrode.

[0584] In this way, electrocardiogram (ECG) signals can be measured using individually set ECG electrodes.

[0585] Using the measurement method provided in this application, users' electrocardiogram signals can be measured anytime and anywhere, as well as physiological parameters such as blood glucose, blood ketones, blood lactic acid, and uric acid.

[0588] In some embodiments, a microneedle sensor may refer to a sensor with a shape similar to a microneedle, and the microneedle sensor may have multiple electrodes disposed inside. Thus, a first electrode group and a second electrode group can be disposed in the microneedle sensor.

[0589] In one possible implementation, the first electronic device further includes a first array sensor and a second array sensor, the first array sensor including a first electrode group and the second array sensor including a second electrode group.

[0592] In this way, the first electrode group and the second electrode group can be arranged in the array sensor in the form of arrays.

[0593] In one possible implementation, the first electronic device further includes a first microneedle sensor and a second array sensor, the first microneedle sensor including a first electrode group and the second array sensor including a second electrode group.

[0594] In this way, the first electrode group can be set in the microneedle sensor, and the second electrode group can be set in the array sensor in the form of an array.

[0598] In one possible implementation, before determining the electrocardiogram (ECG) signal via the first electrode group and the second electrode group, the method further includes: determining that a second condition is met, the second condition including any one or more of the following: receiving second information sent by a second electronic device, the second information being used to instruct the first electronic device to determine the ECG signal; detecting that the first electrode group and the second electrode group are implanted in subcutaneous tissue; detecting that a first physiological parameter does not belong to a first interval.

[0599] Thus, the second condition can be the triggering condition for determining the electrocardiogram signal.

[0600] The second condition can be monitoring condition 2 in the embodiment shown in Figure 5A above.

[0601] In one possible implementation, after determining the first physiological parameter through the first electrode group, the method further includes: outputting the first physiological parameter, or sending the first physiological parameter to a second electronic device.
