[0003] With the continuous development of electronic technology, more and more electronic devices have health monitoring functions, so that users can understand their health status in real time.

[0004] Electronic devices can react with specific substances (such as glucose and ketone bodies) in the interstitial fluid through electrochemical electrodes implanted in the user's subcutaneous tissue, generating a reaction current. By measuring the magnitude of this reaction current, the content of the specific substance in the interstitial fluid can be determined, thereby determining the user's physiological parameters. Physiological parameters such as blood sugar and blood ketones can be measured using this method.

[0005] However, the reaction between electrochemical electrodes and specific substances in tissue fluid is affected by temperature. Temperature changes will affect the magnitude of the reaction current, resulting in errors in the measured physiological parameters. Summary of the Invention

[0095] The following is a clear and detailed description of the technical solutions in the embodiments of the present application in conjunction with the accompanying drawings. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B; "and / or" in the text is only a description of the association relationship between related objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present application, "multiple" means two or more than two.

[0096] In the following, the terms "first" and "second" are used for descriptive purposes only and should not be understood to imply or suggest relative importance or implicitly indicate the number of the technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of this application, unless otherwise specified, "plurality" means two or more.

[0097] The term "user interface (UI)" in the following embodiments of this application refers to a medium interface for interaction and information exchange between an application or operating system and a user, which realizes the conversion between the internal form of information and the form acceptable to the user. The user interface is a source code written in a specific computer language such as Java and extensible markup language (XML). The interface source code is parsed and rendered on an electronic device and finally presented as content that the user can recognize. The commonly used form of user interface is graphical user interface (GUI), which refers to a user interface related to computer operations that is displayed in a graphical manner. It can be a visual interface element such as text, icons, buttons, menus, tabs, text boxes, dialog boxes, status bars, navigation bars, widgets, etc. displayed on the display screen of an electronic device.

[0098] The following introduces some terms involved in the embodiments of this application.

[0099] Blood sugar: Blood sugar refers to the level of glucose in the blood. Glucose is a vital component of the human body and a key source of energy. The human body requires a significant amount of sugar daily to fuel the normal functioning of various tissues and organs. Blood sugar must be maintained within a certain range to meet the needs of various organs and tissues. High blood sugar levels can easily lead to diabetes, while low blood sugar levels can lead to insufficient energy for organs, resulting in serious consequences.

[0100] Blood ketones: Blood ketones refer to the level of ketone bodies in the blood. Exercise metabolizes muscle and fat, producing ketone bodies that enter the bloodstream. A normal blood ketone level does not negatively impact the body. However, elevated blood ketone levels (e.g., above a certain threshold) can lead to acidosis.

[0101] Uric acid: Uric acid is the end product of purine metabolism. It is a trioxypurine whose alcohol form is weakly acidic. Uric acid is present in the human body and is excreted through urine. An imbalance between uric acid production and excretion can easily lead to elevated blood uric acid levels, which can cause disease. Uric acid is primarily produced in the liver, with most of it being excreted in urine via glomerular filtration. Therefore, uric acid monitoring can help determine the health of a user's liver and kidney function.

[0102] 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, primarily produced by red blood cells, striated muscle, and brain tissue. Its concentration depends primarily on the synthesis rate and metabolic rate of the liver and kidneys. Lactate monitoring measures blood lactate concentration and helps determine whether a user's liver and kidney function are normal.

[0103] Electrochemical electrode: The electrochemical electrode reacts with a specific substance to form a current or voltage. In the embodiment of the present application, the electrochemical electrode can be used to measure one or more physiological parameters, such as blood glucose, blood ketones, uric acid, blood lactate, etc. Electrochemical electrodes can include the following according to different 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 system and three-electrode system.

[0104] Working electrode: The working electrode (WE), also known as the research electrode, is the electrode used to generate the reaction being studied. For example, in the case of an electrochemical electrode used to measure blood sugar, the working electrode contains the enzyme glucosidase that reacts with glucose.

[0105] Counter electrode: The counter electrode (CE), also known as the auxiliary electrode, can form a circuit through the subcutaneous tissue and the working electrode, allowing the working electrode current to flow smoothly to ensure that the reaction being studied occurs on the working electrode.

[0106] Reference electrode: A reference electrode (RE) is an electrode with a known potential that is close to ideal and non-polarizable. Almost no current flows through the reference electrode, and the reference electrode is used to control the voltage of the working electrode.

[0107] Three-electrode system: A three-electrode system can include a working electrode, a counter electrode, and a reference electrode. For a description of the functions of the working electrode, reference electrode, and counter electrode in a three-electrode system, refer to the relevant content in the above glossary.

[0108] Two-electrode system: A two-electrode system can 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 generate the reaction of interest, and the counter electrode (or reference electrode) can form a circuit with the working electrode to ensure that the working electrode generates the reaction current. Optionally, the counter electrode can also be used to control the voltage of the working electrode.

[0109] Continuous glucose monitoring device: A continuous glucose monitoring (CGM) device is an electronic device used to measure blood sugar. The CGM device may include an electrochemical electrode, in which a glucose enzyme (such as glucose oxidase, etc.) may be provided. After the CGM device is implanted subcutaneously in the user, the glucose enzyme in the electrochemical electrode may react with the glucose in the tissue fluid to generate an electric current. The CGM device can measure the current generated by the reaction of the glucose enzyme with glucose, and determine the glucose concentration in the user's tissue fluid based on the magnitude of the current, and determine the glucose concentration in the user's blood based on the glucose concentration in the tissue fluid, that is, the user's blood sugar value.

[0110] Enzymes: Enzymes are proteins or ribonucleic acids (RNA) produced by living cells that are highly specific and catalytically efficient for their substrates. The ability of an enzyme to catalyze a chemical reaction is called enzyme activity (also known as enzyme activity). Enzyme activity is temperature-dependent. Different enzymes have different optimal temperatures. Enzymes are most active and catalytically efficient when their environment is at their optimal temperature.

[0111] The following describes the principles of measuring physiological parameters using electrochemical electrodes.

[0112] When the electrochemical electrode is implanted in the subcutaneous tissue, it can react with specific chemical substances (e.g., glucose, ketone bodies, uric acid, lactic acid, etc.) to generate a reaction current. In some embodiments, the electrochemical electrode can include an enzyme capable of reacting with specific chemical substances (e.g., glucose, ketone bodies, uric acid, lactic acid, etc.), such as glucose oxidase. The magnitude of the reaction current is related to the content of the specific chemical substance in the subcutaneous tissue. The higher the content of the specific chemical substance, the greater the magnitude of the current generated. Therefore, the user's physiological parameters can be determined based on the magnitude of the reaction current.

[0113] As explained above regarding enzymes, enzyme activity is related to the temperature of the environment in which the enzyme is currently located (i.e., the user's body temperature). When the user's body temperature is optimal for that type of enzyme, the enzyme activity in the electrochemical electrode is highest, and the current generated by the electrochemical electrode and the specific chemical substance is greater. When the user's body temperature changes, the enzyme activity and the current also change accordingly. Therefore, changes in the user's body temperature can significantly affect the measurement results.

[0114] It should be noted that in other embodiments, the electrochemical electrodes may also contain other substances that can cause changes in specific chemical substances (or have a catalytic effect). In this case, the ambient temperature of the chemical reaction is also a factor affecting the chemical reaction. That is, the user's body temperature can also affect the current generated by the chemical reaction. Therefore, changes in the user's body temperature can have a significant impact on the measurement results.

[0115] It can be understood that the above embodiments are merely illustrative of how the user's body temperature affects the measurement results of physiological parameters such as blood sugar, blood ketones, and uric acid. In the embodiments of the present application, the physiological parameters affected by body temperature may also include more, fewer, or different physiological parameters than those in the above embodiments, and the present application does not limit this.

[0116] The following introduces the system architecture of a measurement system 10 provided in an embodiment of the present application.

[0117] As shown in Figure 1, the measurement system 10 may include an electronic device 100 and an electronic device 200. A communication connection may be established between the electronic device 100 and the electronic device 200. The above-mentioned communication connection may be a wired communication connection or a wireless communication connection. The wireless communication connection may be a wireless communication connection established by the electronic device 100 and the electronic device 200 using any one of wireless communication technologies such as wireless local area networks (WLAN) (such as wireless fidelity (Wi-Fi) networks), Bluetooth (BT), global navigation satellite system (GNSS), frequency modulation (FM), near field communication (NFC), infrared technology (IR), NearLink, intrabody communication (IBC), etc.

[0118] In some embodiments, upon detecting that a monitoring condition is met, the electronic device 100 may send a message 1 to the electronic device 200.

[0194] The flexible holder 303 may be disposed on the bottom housing 301 , the PCB 302 may be disposed between the bottom housing 301 and the flexible holder 303 , and the on-skin portion of the invasive sensor 307 may be disposed on the flexible holder 303 .

[0195] In the embodiment shown in FIG3B , the one or more conductive elements 304 can be embedded in the flexible holder 303, and the lower end of the conductive element 304 can contact the PCB 302, and the upper end of the conductive element 304 can contact the skin portion of the invasive sensor 307. In this way, the PCB 302 can be connected to the skin portion of the invasive sensor 307 through the one or more conductive elements 304 to obtain the reaction current conducted by the invasive sensor 307. It will be understood that the embodiment herein is merely an example of how the PCB 302 and the invasive sensor 307 can be connected through the conductive elements 304. In the embodiment of the present application, the PCB 302 and the invasive sensor 307 can also be connected through more, fewer, or conductive elements of different shapes than those in the embodiment herein, or through different parts of the conductive elements, and the present application does not limit this.

[0196] In addition, the flexible holder 303 may also be embedded with one or more temperature sensing elements, such as temperature sensing element 305 and temperature sensing element 306. The upper end of each temperature sensing element may be connected to the skin portion connected to the invasive sensor 307, and the lower end of each temperature sensing element may be connected to the PCB 302. Optionally, the gaps between the temperature sensing element and the PCB 302, and the gaps between the temperature sensing element and the PCB 302, may be filled with a thermally conductive material, such as a thermally conductive gel. Filling with a thermally conductive material can reduce thermal resistance and improve temperature detection efficiency. In this way, the temperature sensing element can be connected to the PCB 302, and the temperature of the temperature electrode in the invasive sensor 307 can be determined based on the heat conducted by the temperature electrode, thereby determining the user's body temperature. It should be understood that the embodiments herein are merely illustrative of how the temperature sensing element can be connected to the PCB 302 and the invasive sensor 307, respectively. In the embodiments of the present application, the connection method and connection location of the temperature sensing element to the invasive sensor 307 and the PCB 302 may also differ from the above embodiments, and this application is not limited thereto.

[0197] The invasive sensor 307 may include multiple electrodes, which may include one or more electrochemical electrodes (e.g., a working electrode, a reference electrode, and a counter electrode), and may also include one or more temperature electrodes. One end of the temperature electrode on the invasive sensor 307 may be implanted in the subcutaneous tissue, and the other end may be connected to a temperature detection element (e.g., a temperature detection element connected via a thermally conductive gel). The temperature electrode is used to conduct heat from the subcutaneous tissue to the temperature detection element. One end of the electrochemical electrode on the invasive sensor 307 may be implanted in the subcutaneous tissue, and the other end may be connected to the PCB 302 (e.g., connected to the PCB 302 via a conductive element 304). The electrochemical electrode is used to generate a reaction current in the subcutaneous tissue and transmit the reaction current to the PCB 302. The invasive sensor 307 may include an epidermal portion and a subcutaneous portion. The subcutaneous portion is used to be implanted in the subcutaneous tissue, and the epidermal portion can be used to connect to the temperature detection element and the PCB 302. That is, the temperature electrode on the epidermal portion is connected to the temperature detection element, and the electrochemical electrode is connected to the PCB 302. It should be noted that the temperature electrode can be made of a metal with excellent thermal conductivity, such as gold or silver. The material of the electrochemical electrode may be related to the measured physiological parameters of the user.

[0198] In the embodiment shown in Figures 3A and 3B, the temperature sensing element and the conductive element 304 are both embedded in the flexible holder 303, with the upper ends connected to the invasive sensor 307 and the lower ends connected to the PCB 302. Therefore, in order to achieve the purpose of conducting reaction current and heat, the temperature electrode and the electrochemical electrode should be arranged on the same side of the invasive sensor 307, that is, the side in contact with the temperature sensing element and the conductive element 304 (also referred to as side A). In this case, the electrodes in the invasive sensor 307 can adopt a single-sided layout. The specific details of the single-sided layout can be referred to the relevant content of the embodiment shown in Figures 3C and 3D below.

[0199] The following describes an arrangement of electrodes in an intrusive sensor 307 provided in an embodiment of the present application.

[0200] If the positional relationship between the components and the bottom case of the electronic device 200 is the positional relationship shown in Figures 3A and 3B above, then the schematic diagram of the arrangement of the multiple electrodes in the invasive sensor 307 in the electronic device 200 can refer to the embodiment shown in Figures 3C and 3D. It should be noted that in this embodiment of the present application, the invasive sensor 307 may include multiple surfaces, such as surface A and surface B. Surface A and surface B may be two opposing surfaces of the invasive sensor 307.

[0201] FIG3C is a schematic diagram of the electrode arrangement on the A side of an invasive sensor 307 provided in an embodiment of the present application.

[0202] As shown in Figure 3C, the A surface of the invasive sensor 307 is the side that contacts the temperature detection element and the conductive element 304. The A surface of the invasive sensor 307 may also include the A surface of the subcutaneous part and the A surface of the supracutaneous part. The subcutaneous part refers to the part that is implanted into the subcutaneous tissue of the user during the measurement process, and the supracutaneous part refers to the part that is not implanted into the subcutaneous tissue of the user during the measurement process. The A surface of the invasive sensor 307 may be an irregular polygon as shown in Figure 3C. It is understandable that in the embodiment of the present application, the A surface of the invasive sensor 307 may also adopt a different shape from the embodiment shown in Figure 3C, and the present application does not limit it here.

[0203] The A surface of the invasive sensor 307 may include one or more temperature electrodes, such as temperature electrode 1, temperature electrode 2, etc. The A surface of the invasive sensor 307 may also include one or more electrochemical electrodes, such as a working electrode, a reference electrode, and a counter electrode. On the A surface of the invasive sensor 307, the above-mentioned multiple electrodes do not contact each other. Each electrode may include two ends and a wire connecting the two ends. One end of the electrode may be called the measuring end of the electrode, and the other end may be called the conducting end of the electrode. The measuring end of the temperature electrode is used to obtain heat in the user's subcutaneous tissue. Therefore, the measuring end of the temperature electrode can be set in the subcutaneous part of the invasive sensor 307. The measuring end of the temperature electrode can conduct the heat of the subcutaneous tissue to the conducting end of the temperature electrode through the wire. The conducting end of the temperature electrode is used to conduct heat to the temperature detection element. Therefore, the conducting end of the temperature electrode can be set in the skin part of the invasive sensor 307, and the conducting end of the temperature electrode can be connected to the temperature detection element. The measuring end of the electrochemical electrode can be used to react with the subcutaneous tissue to generate a reaction current. Therefore, the measuring end of the electrochemical electrode can be set in the subcutaneous part of the invasive sensor 307. The measuring end of the electrochemical electrode can conduct the reaction current to the conductive end of the electrochemical electrode through a wire. The conductive end of the electrochemical electrode is used to conduct the generated reaction current to PCB302. Therefore, the conductive end of the electrochemical electrode can be set in the skin part of the invasive sensor 307, and the conductive end of the electrochemical electrode can be connected to PCB302 (for example, connected through a conductive element 304). The measuring end and the conductive end of the same electrode can be connected by a wire. The wire material of different electrodes can be different. For example, the temperature electrode can be made of a material with good thermal conductivity such as gold or silver. Optionally, the wire portion of the temperature electrode can be coated with an insulating layer to avoid the influence of the internal environment and improve the accuracy of temperature detection.

[0204] It should be noted that, in an embodiment of the present application, the electrochemical electrode in the invasive sensor 307 may include only a working electrode, or may include only a working electrode and a counter electrode, or may include a working electrode, a counter electrode, and a reference electrode. In the case where the electrochemical electrode of the invasive sensor 307 includes only a working electrode, the temperature electrode on the invasive sensor 307 can serve as a counter electrode and the electrochemical electrode to constitute a two-electrode system to ensure the generation and conduction of the reaction current. In the case where the electrochemical electrode on the invasive sensor 307 includes only a working electrode and a counter electrode, the working electrode and the counter electrode can also constitute a two-electrode system to ensure the generation and conduction of the reaction current. In other embodiments, in the case where the electrochemical electrode on the invasive sensor 307 includes only a working electrode and a counter electrode (or a reference electrode), the temperature electrode, the working electrode, and the counter electrode (or a reference electrode) can also constitute a three-electrode system to ensure the generation and conduction of the reaction current, and the temperature electrode can serve as a reference electrode or a counter electrode. When the electrochemical electrodes in the invasive sensor 307 include a working electrode, a counter electrode and a reference electrode, the three electrochemical electrodes can constitute a three-electrode system to ensure the generation and conduction of the reaction current, and the voltage of the working electrode can also be controlled by the reference electrode.

[0205] The specific functions of the different electrodes in the three-electrode system and the two-electrode system can be described in the above-mentioned glossary, which will not be repeated here. It is understood that in the following embodiments, the types and numbers of electrochemical electrodes on the invasive sensor 307 can refer to the embodiments herein.

[0206] In some embodiments, if there are multiple temperature electrodes on the invasive sensor 307, the multiple temperature electrodes can optionally be symmetrically distributed on the A surface of the invasive sensor 307. For example, if the temperature electrodes include temperature electrode 1 and temperature electrode 2, temperature electrode 1 and temperature electrode 2 can be symmetrically distributed on the A surface of the invasive sensor 307. In this way, the temperature of multiple locations in the subcutaneous tissue can be determined by the multiple temperature electrodes, and the user's body temperature can be determined based on the temperatures of the multiple locations, thereby improving the accuracy of body temperature measurement.

[0207] For example, in the embodiment shown in FIG3C , the invasive sensor 307 may include two temperature electrodes, a working electrode, a reference electrode, and a counter electrode. In this case, the temperature electrodes and electrochemical electrodes on surface A of the invasive sensor 307 may be arranged in the following order: temperature electrode 1, reference electrode, working electrode, counter electrode, temperature electrode 2. It will be understood that the embodiment herein is merely an example, and in embodiments of the present application, the temperature electrodes and electrochemical electrodes may be arranged on surface A of the invasive sensor 307 in an arrangement order different from that of the above embodiment. Furthermore, in other embodiments, the electrodes arranged on surface A of the invasive sensor 307 may include more, fewer, or different temperature electrodes, electrochemical electrodes, etc. than those of the above embodiment, and this application does not limit this.

[0208] FIG3D is a schematic diagram of the electrode arrangement on the B side of an invasive sensor 307 provided in an embodiment of the present application.

[0209] As shown in FIG3D , side B of the invasive sensor 307 may be opposite side A. Side B of the invasive sensor 307 may not be provided with any electrodes. That is, all electrodes (including temperature electrodes, electrochemical electrodes, etc.) on the invasive sensor 307 are provided on side A of the invasive sensor 307.

[0210] It should be understood that the embodiments shown in Figures 3C and 3D are merely illustrative of how all electrodes of the invasive sensor 307 can be arranged on the same surface of the invasive sensor 307. In embodiments of the present application, the invasive sensor 307 may include more, fewer, or different electrodes than those in the aforementioned embodiments, such as more or fewer temperature electrodes, or more or fewer electrochemical electrodes. Furthermore, the arrangement order of the electrodes in the invasive sensor 307 may also differ from that in the aforementioned embodiments, and this application does not impose any limitation thereto.

[0211] It should be noted that, in some embodiments, the invasive sensor 307 can be a thin sheet including the A surface shown in Figure 3C and the B surface shown in Figure 3D, or it can be a polyhedron including the above-mentioned A surface and B surface, such as a triangular prism, a rectangular parallelepiped, etc. In other embodiments, the invasive sensor 307 can also be a cylinder including a temperature electrode and an electrochemical electrode, etc. This application does not limit the specific shape of the invasive sensor 307.

[0212] FIG4A is a schematic diagram showing the positional relationship between components and a bottom housing in another electronic device 200 provided in an embodiment of the present application.

[0213] As shown in FIG4A , electronic device 200 may include a bottom housing 301, a printed circuit board (PCB) 302, one or more temperature detection elements (e.g., temperature detection element 305 and temperature detection element 306), an intrusive sensor 307, etc. Optionally, electronic device 200 may further include any one or more of the following: a flexible clip 303, one or more conductive elements 304, etc. In some embodiments, PCB 302 may include an MCU.

[0214] In some embodiments, the conductive element 304 can be used to connect the invasive sensor 307 and the PCB 302 to facilitate the conduction of the reaction current on the invasive sensor 307 to the PCB 302. In the embodiment shown in Figure 4A, since the skin portion of the invasive sensor 307 and the PCB 302 are respectively located on the side and above the flexible holder 303, in order to connect the invasive sensor 307 and the PCB 302, the one or more conductive elements 304 can be set on the bottom shell 301 so that the side of the conductive element 304 can contact the invasive sensor 307 and the PCB 302 at the same time to facilitate the conduction of the reaction current to the PCB 302. In some embodiments, the conductive element 304 can be conductive rubber. In other embodiments, the conductive element 304 can also be made of other conductive materials, which is not limited in this application.

[0215] The functions of other components in the electronic device 200 and the positional relationships between the components can be referred to the relevant description of the embodiment shown in FIG. 3A above, and will not be repeated here.

[0216] It can be understood that Figure 4A only exemplifies the positional relationship between the components and the bottom shell in an electronic device 200. In the embodiments of the present application, the electronic device 200 may also include more, fewer or different components than the above embodiments, and the positional relationship between the various components may also be different from the above embodiments. This application does not limit this.

[0217] By cutting the electronic device 200 shown in FIG4A along the vertical cross-section shown in FIG4A , the vertical cross-section schematic diagrams of the electronic device 200 shown in FIG4B and FIG4C can be obtained. It should be noted that the vertical cross-section shown in FIG4B is a cross-section including the temperature detection element, and the vertical cross-section shown in FIG4C is a cross-section including the conductive element 304.

[0218] As shown in FIG4B , the electronic device 200 may include a bottom housing 301 , a PCB 302 , one or more temperature detection elements (eg, a temperature detection element 305 and a temperature detection element 306 ), an intrusive sensor 307 , etc. Optionally, the electronic device 200 may further include a flexible holder 303 , etc.

[0219] In some embodiments, the flexible holder 303 may be disposed on the bottom housing 301 , the PCB 302 may be disposed above the flexible holder 303 , and the on-skin portion of the invasive sensor 307 may be disposed between the bottom housing 301 and the flexible holder 303 .

[0220] In the embodiment shown in FIG4B , since the skin portion of the invasive sensor 307 and the PCB 302 are respectively located above and below the flexible holder 303, in order to connect the invasive sensor 307 and the PCB 302, the one or more temperature detection elements (such as the temperature detection element 305 and the temperature detection element 306) can be embedded in the flexible holder 303. In this way, each temperature detection element can contact both the PCB 302 and the C-surface of the invasive sensor 307. Optionally, the gap between the temperature detection element and the PCB 302, and the gap between the temperature detection element and the invasive sensor 307, can also be filled with a thermally conductive material, such as a thermally conductive gel, etc. Filling with a thermally conductive material can reduce thermal resistance and improve the efficiency of temperature detection.

[0221] The invasive sensor 307 may include multiple electrodes, which may include one or more electrochemical electrodes (e.g., a working electrode, a reference electrode, and a counter electrode), and may also include one or more temperature electrodes. One end of the temperature electrode on the invasive sensor 307 may be implanted in the subcutaneous tissue, and the other end may be connected to a temperature detection element (e.g., a temperature detection element connected via a thermally conductive gel). The temperature electrode is used to conduct heat from the subcutaneous tissue to the temperature detection element. One end of the electrochemical electrode on the invasive sensor 307 may be implanted in the subcutaneous tissue, and the other end may be connected to the PCB 302 (e.g., connected to the PCB 302 via a conductive element 304). The electrochemical electrode is used to generate a reaction current in the subcutaneous tissue and transmit the reaction current to the PCB 302. The invasive sensor 307 may include an epidermal portion and a subcutaneous portion. The subcutaneous portion is used to be implanted in the subcutaneous tissue, and the epidermal portion can be used to connect to the temperature detection element and the PCB 302. That is, the temperature electrode on the epidermal portion is connected to the temperature detection element, and the electrochemical electrode is connected to the PCB 302. It should be noted that the temperature electrode can be made of a metal with excellent thermal conductivity, such as gold or silver. The material of the electrochemical electrode may be related to the measured physiological parameters of the user.

[0222] It should be noted that, in order to achieve the purpose of heat conduction, the surface of the intrusive sensor 307 that contacts the temperature detection element should be provided with a temperature electrode. Therefore, the temperature electrode should be provided on the surface of the intrusive sensor 307 that contacts the temperature detection element, that is, on the C surface of the intrusive sensor 307.

[0223] As shown in FIG4C , electronic device 200 may include a bottom housing 301, a PCB 302, an intrusive sensor 307, and the like. Optionally, electronic device 200 may further include any one or more of the following: a flexible clip 303, one or more conductive elements 304, and the like. The positional relationship between bottom housing 301, PCB 302, flexible clip 303, and intrusive sensor 307 can be found in the description of the embodiments shown in FIG4A and FIG4B above, and will not be further elaborated here.

[0224] In some embodiments, the one or more conductive elements 304 can be disposed on the bottom housing 301, and the conductive elements 304 can be used to connect the PCB 302 and the skin-surfacing portion of the invasive sensor 307. For example, the top end of the side edge of the conductive element 304 can contact the PCB 302, and the bottom end of the side edge of the conductive element 304 can contact the skin-surfacing portion of the invasive sensor 307. In this way, the PCB 302 can be connected to the skin-surfacing portion of the invasive sensor 307 via the one or more conductive elements 304 to obtain the reaction current conducted by the invasive sensor 307. It will be understood that the embodiment herein is merely an example of how the PCB 302 and the invasive sensor 307 can be connected via the conductive elements 304. In the embodiment of the present application, the PCB 302 and the invasive sensor 307 can also be connected via more, fewer, or conductive elements of different shapes than those in the embodiment herein, or connected via different locations of the conductive elements, and the present application is not limited thereto.

[0225] It should be noted that, in order to conduct the reaction current, the surface of the invasive sensor 307 that contacts the conductive element 304 should be provided with an electrochemical electrode. Therefore, the electrochemical electrode should be provided on the surface that contacts the conductive element 304, i.e., surface D of the invasive sensor 307 shown in FIG4E . Surface D and surface C are opposite surfaces of the invasive sensor 307.

[0226] In this case, each electrode in the intrusive sensor 307 may be arranged on both sides. For details of the double-sided layout, reference may be made to the relevant contents in the embodiments shown in FIG. 4D to FIG. 4E below.

[0227] The following describes an arrangement of electrodes in an intrusive sensor 307 provided in an embodiment of the present application.

[0228] If the positional relationship between the components and the bottom case of the electronic device 200 is the positional relationship shown in Figures 4A-4C above, then the arrangement diagram of the multiple electrodes in the intrusive sensor 307 in the electronic device 200 can refer to the embodiment shown in Figures 4D-4E. It should be noted that in this embodiment of the application, the intrusive sensor 307 may include a C surface and a D surface.

[0229] FIG4D is a schematic diagram of the C-surface electrode arrangement of an invasive sensor 307 provided in an embodiment of the present application.

[0230] As shown in Figure 4D, the C-surface of the invasive sensor 307 is the surface in contact with the temperature detection element. The C-surface of the invasive sensor 307 may also include the C-surface of the subcutaneous part and the C-surface of the supracutaneous part. The subcutaneous part refers to the part implanted into the subcutaneous tissue of the user during the measurement process, and the supracutaneous part refers to the part that is not implanted into the subcutaneous tissue of the user during the measurement process. In the embodiment shown in Figure 4D, the C-surface of the subcutaneous part may be a polygon, and the C-surface of the supracutaneous part may be a polygon. It is understandable that in the embodiment of the present application, the C-surface of the supracutaneous part and the C-surface of the subcutaneous part may also adopt different shapes from the embodiment shown in Figure 4D, and the present application does not limit this.

[0231] The C-side of the invasive sensor 307 may include one or more temperature electrodes, such as temperature electrode 1, temperature electrode 2, and the like. Each temperature electrode may include two ends and a wire connecting the two ends. One end of the temperature electrode may be referred to as the measuring end of the temperature electrode, and the other end may be referred to as the conducting end of the temperature electrode. The measuring end of the temperature electrode is used to obtain heat from the subcutaneous tissue and conduct the heat to the conducting end of the temperature electrode through a wire. Therefore, the measuring end of the temperature electrode may be set in the subcutaneous part of the invasive sensor 307. The temperature conducting end is used to conduct the heat conducted by the measuring end to the temperature detection element. Therefore, the conducting end of the temperature electrode may be set in the supracutaneous part of the invasive sensor 307. The measuring end and the conducting end of the temperature electrode may be connected by a wire. In some embodiments, the temperature electrode may be made of a material with good thermal conductivity such as gold or silver. Optionally, the wire portion of the temperature electrode may be coated with an insulating layer to avoid the influence of the internal environment and improve the accuracy of temperature detection.

[0232] In some embodiments, if there are two temperature electrodes on the invasive sensor 307, for example, temperature electrode 1 and temperature electrode 2, temperature electrode 1 and temperature electrode 2 can be symmetrically distributed on the C-surface of the invasive sensor 307. In this way, the temperatures at two symmetrical positions can be measured by the two temperature electrodes, and the user's body temperature can be determined based on the temperatures at the two symmetrical positions, thereby improving the accuracy of body temperature measurement.

[0233] FIG4E is a schematic diagram of the D-surface electrode arrangement of an invasive sensor 307 provided in an embodiment of the present application.

[0234] As shown in FIG4E , the D surface of the invasive sensor 307 is the surface that contacts the conductive element 304. The D surface of the invasive sensor 307 may be opposite the C surface, i.e., the C and D surfaces are parallel to each other. The D surface of the invasive sensor 307 may include a subcutaneous D surface and a supracutaneous D surface. The shapes of the supracutaneous D surface and the subcutaneous D surface may refer to the shapes of the supracutaneous C surface and the subcutaneous C surface in the embodiment shown in FIG4D .

[0235] The D surface of the invasive sensor 307 may also include one or more electrochemical electrodes, such as a working electrode, a reference electrode, and a counter electrode. On the D surface of the invasive sensor 307, the above-mentioned multiple electrochemical electrodes do not contact each other. Each electrochemical electrode may include two ends and a wire connecting the two ends. One end of the electrochemical electrode may be referred to as the measuring end of the electrochemical electrode, and the other end may be referred to as the conducting end of the electrochemical electrode. The measuring end of the electrochemical electrode is used to generate a reaction current. Therefore, the measuring end of the electrochemical electrode can be set in the subcutaneous part of the invasive sensor 307. The conducting end of the electrochemical electrode is used to conduct the measured reaction current to PCB302. Therefore, the conducting end of the electrochemical electrode can be set in the supracutaneous part of the invasive sensor 307. The measuring end and the conducting end of the electrochemical electrode can be connected by a wire. The wire material of different electrodes may be different.

[0236] Exemplarily, the electrochemical electrodes on the D surface of the invasive sensor 307 can be arranged in the following order: reference electrode, working electrode, counter electrode. It will be appreciated that this embodiment is merely illustrative, and in embodiments of the present application, the electrochemical electrodes can be arranged on the D surface of the invasive sensor 307 in a different arrangement order than in the above embodiment. Furthermore, in other embodiments, the electrodes arranged on the D surface of the invasive sensor 307 can include more, fewer, or different temperature electrodes and electrochemical electrodes than in the above embodiment, and this application does not limit this.

[0237] By using the arrangement shown in Figures 4D-4E, multiple electrodes of the invasive sensor 307 can be arranged on different sides of the invasive sensor 307. This can reduce the number of electrodes arranged on a single side of the invasive sensor 307, thereby reducing the width of the invasive sensor 307 implanted under the user's skin, reducing the foreign body sensation during implantation, and providing the user with a better user experience.

[0238] It is understood that the embodiments shown in Figures 4D and 4E are merely illustrative of how multiple electrodes can be arranged on different surfaces of the invasive sensor 307. In embodiments of the present application, the invasive sensor 307 may include more, fewer, or different electrodes than those in the aforementioned embodiments, such as more or fewer temperature electrodes, or more or fewer electrochemical electrodes. Furthermore, the arrangement order of the electrodes in the invasive sensor 307 may differ from that in the aforementioned embodiments. Moreover, in other embodiments, the electrodes may be distributed on multiple different surfaces of the invasive sensor 307, and this application does not limit this.

[0239] It should be noted that in some embodiments, the invasive sensor 307 may be a thin sheet including the C surface shown in FIG. 4D and the D surface shown in FIG. 4E , or a polyhedron including the C and D surfaces, such as a triangular prism or a rectangular parallelepiped. In other embodiments, the invasive sensor 307 may be a cylinder including temperature electrodes and electrochemical electrodes. This application does not limit the specific shape of the invasive sensor 307. In the case where the invasive sensor 307 includes two or more surfaces, the invasive sensor 307 may also have one or more temperature electrodes and one or more electrochemical electrodes disposed on different surfaces, which is not limited in this application.

[0240] It should be noted that the above Figures 3A to 3D and Figures 4A to 4E are only two examples. In the embodiment of the present application, the electronic device 200 may also include more, fewer, or different elements than the above embodiment, and the positional relationship between the elements may also be different from the above embodiment. The present application does not limit this. In addition, if the positional relationship between the PCB 302 and the invasive sensor 307 is different from the above embodiment, the arrangement of the temperature detection element, the conductive element 304, and the electrodes on the invasive sensor 307 can be adjusted accordingly to ensure that the temperature electrode on the invasive sensor 307 can be connected to the temperature detection element, and the electrochemical electrode on the invasive sensor 307 can be connected to the PCB 302 (for example, connected to the PCB 302 via the conductive element 304).

[0241] In one possible implementation, the temperature electrode (e.g., temperature electrode 1) in the invasive sensor 307 can simultaneously serve as a reference electrode or a counter electrode in a three-electrode system, or as a counter electrode in a two-electrode system. In this case, the temperature electrode 1 can include two conductive ends, one conductive end is used to connect to the temperature detection element (e.g., connected via temperature gel), and the other conductive end can be connected to PCB302. Moreover, in this case, the conductive end of the temperature electrode connected to PCB302 can also be connected to the measuring end of the temperature electrode via the wire of the temperature electrode, that is, both conductive ends of the temperature electrode can be connected to the measuring end of the temperature electrode via the wire of the temperature electrode. It is understandable that the multiple temperature electrodes in the invasive sensor 307 can also serve as the reference electrode and the counter electrode in the three-electrode system, respectively, to form a three-electrode system with the working electrode to measure the physiological parameters of the user, and this application does not limit this.

[0242] It can be understood that when the temperature electrode is also used as a counter electrode, the temperature electrode and the working electrode can constitute a two-electrode system; when the temperature electrode is also used as a reference electrode (or counter electrode), the temperature electrode, the working electrode and the counter electrode (or reference electrode) can constitute a three-electrode system.

[0243] The above-mentioned two-electrode system and / or three-electrode system can be used to measure physiological parameters in the embodiments of the present application; at the same time, the temperature electrode can also be used to measure the user's body temperature.

[0244] In some embodiments, the invasive sensor 307 may be provided with multiple working electrodes. These multiple working electrodes may be made of different materials or contain different enzymes, etc., to react chemically with different chemical substances (e.g., blood glucose, blood ketones, uric acid, etc.) in the tissue fluid to generate different reaction currents. In this way, the invasive sensor 307 can simultaneously obtain physiological data of multiple physiological parameters.

[0245] In other embodiments, when the invasive sensor 307 includes multiple working electrodes, at least two of the multiple working electrodes may be made of the same material, and one of the working electrodes may contain an enzyme for reacting with a specific chemical substance, while the other working electrodes may not contain the enzyme. In this case, the invasive sensor 307 can be calibrated based on the reaction currents conducted by the multiple working electrodes to obtain a more accurate reaction current.

[0253] The following describes a specific method in which the electronic device 100 determines whether the monitoring conditions are met.

[0254] In some embodiments, the electronic device 100 may obtain user information and determine whether the electronic device 100 meets the monitoring conditions 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, exercise information, exercise equipment information, posture information, location information, and interaction information.

[0256] The following describes some methods for electronic devices 100 to detect user information provided by embodiments of the present application.

[0257] For example, the electronic device 100 can detect the user's motion information and posture information through devices such as gyroscope sensors and accelerometers; the electronic device 100 can detect the user's physiological information such as heart rate and blood pressure through devices such as PPG modules; the electronic device 100 can also collect the user's facial expressions through a camera, and determine the user's emotional state through algorithm models such as image analysis and facial expression analysis; the electronic device 100 can also determine the user's psychological information such as pressure value based on physiological information; the electronic device 100 can also detect the user's interaction information through a touch sensor; the electronic device 100 can detect the user's location information through a position sensor (such as a global positioning chip, etc.); the electronic device 100 can also detect the air pressure of the user's environment based on a pressure sensor, and determine the user's location information such as the altitude based on the air pressure value, and so on.

[0258] It will be understood that the embodiments herein are merely examples. In the embodiments of the present application, the electronic device 100 may include more, fewer, or different devices than those in the above-described embodiments. Moreover, the electronic device 100 may also collect user information through sensors or other devices that are different from those in the above-described embodiments. This application does not limit this.

[0259] The following describes some methods for electronic devices 100 provided in embodiments of the present application to determine whether monitoring conditions are met based on user information.

[0260] If the electronic device 100 determines that any physiological information is abnormal, it determines that the monitoring condition is met. For example, the physiological information abnormality 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.

[0261] If the electronic device 100 determines that the motion information satisfies a preset motion state, the monitoring condition is determined to be satisfied. For example, the preset motion state may include, but is not limited to, any one or more of the following: diving state, mountain climbing state, cycling state, yoga state, swimming state, running state, etc.

[0262] If the electronic device 100 determines that the user's psychological state is abnormal based on the psychological information, the monitoring condition is determined to be met. For example, the abnormal psychological state includes but is not limited to any one or more of the following: the user is frightened, the user is depressed, the user is excited, etc.

[0263] If the electronic device 100 determines that the user is in a preset area based on the location information, the monitoring condition is determined to be met. The preset area may include but is not limited to any one or more of the following: a high altitude area, a deep water area, etc.

[0264] If the electronic device 100 determines that the user's body posture is abnormal based on the posture information, the monitoring condition is determined to be met. For example, the abnormal user's body posture includes but is not limited to any one or more of the following situations: the user falls, the user misses a step, etc.

[0265] If the electronic device 100 determines based on the sports equipment information that the user's sports equipment is abnormal, then the monitoring condition is determined to be met. For example, the abnormality of the user's sports equipment may include, but is not limited to, any one or more of the following: the oxygen remaining in the oxygen cylinder is less than a preset oxygen amount, the bicycle's travel resistance is greater than a preset resistance, the weight of the smart backpack is greater than a preset weight, etc.

[0266] It will be understood that the above embodiments are merely illustrative of various ways of determining whether monitoring conditions are met based on user information. In the embodiments of the present application, the electronic device 100 may also determine whether monitoring conditions are met based on various types of user information. The electronic device 100 may also determine whether monitoring conditions are met based on other information in the user information, and the monitoring conditions may also include more, fewer, or different conditions than those in the above embodiments. This application does not limit these conditions.

[0267] S502 . The electronic device 100 sends information 1 to the electronic device 200 , where the information 1 is used to request the electronic device 200 to send physiological data to the electronic device 100 .

[0268] Step S502 is an optional step.

[0269] In some embodiments, after the physiological monitoring function is turned on, the electronic device 100 may send information 1 to the electronic device 200 .

[0270] In other embodiments, the electronic device 200 may also periodically (or continuously) obtain the user's body temperature and physiological data, and periodically send the physiological data to the electronic device 100. In this case, the electronic device 100 may not perform step S502. Optionally, the electronic device 200 may also periodically send the user's body temperature.

[0271] S503. The electronic device 200 obtains the user's body temperature.

[0272] In one possible implementation, the electronic device 200 may receive and obtain the user's body temperature in response to the information 1 .

[0273] In another possible implementation, the electronic device 100 may also periodically obtain the user's body temperature, for example, periodically collecting the user's body temperature at a fixed time interval of 1 (for example, 5 minutes, 15 minutes, 1 hour, etc.), and recording the time of temperature collection.

[0274] The following describes how the electronic device 200 obtains the user's body temperature.

[0275] FIG6A shows a schematic diagram of a heat transfer path provided in an embodiment of the present application.

[0276] As shown in FIG6A , the heat conduction path may include a temperature electrode and a temperature detection element. Optionally, the temperature electrode and the temperature detection element may be connected by a thermal conductive gel (or other thermal conductive materials).

[0277] Among them, the temperature electrode may include a measuring end, a wire and a conducting end, and the measuring end and the conducting end may be connected by a wire. The measuring end of the temperature electrode may be implanted in the subcutaneous tissue of the user, and the conducting end may be outside the user's body. In the process of measuring the user's body temperature, the measuring end of the temperature electrode may obtain heat from the user's subcutaneous tissue and conduct the heat to the conducting end of the temperature electrode through the wire. The conducting end may conduct the heat transmitted by the measuring end to the temperature detection element. In some embodiments, the conducting end may conduct the heat transmitted by the measuring end to the temperature detection element through a thermally conductive gel (or other thermally conductive materials).

[0278] The temperature detection element can determine the temperature of the user's subcutaneous tissue based on the heat transmitted by the temperature electrode. The temperature of the user's subcutaneous tissue is the user's body temperature.

[0279] It is understandable that the heat transfer path shown in Figure 6A is only an example. In the embodiments of the present application, the heat transfer path may also include more, fewer, or different elements than the above embodiments, for example, not including thermal conductive gel, or including other thermal conductive materials, etc., and the present application does not limit this.

[0280] In some embodiments, the electronic device 200 may include a temperature electrode and a temperature detection element. The heat transfer path formed by the temperature electrode and the temperature detection element can refer to the embodiment shown in Figure 6A above. In this case, the electronic device 200 can use the temperature determined by the temperature detection element as the user's body temperature.

[0281] In other embodiments, the electronic device 200 may also include multiple temperature electrodes and multiple temperature detection elements, and each temperature electrode may form a heat transfer path with a temperature detection element as shown in FIG6A . In this case, the electronic device 200 may measure the temperature of multiple locations in the user's subcutaneous tissue through the multiple temperature electrodes and multiple temperature detection elements, and calculate the user's body temperature based on the multiple temperatures, for example, using the average or median of the multiple temperatures as the user's body temperature, etc., which is not limited in this application.

[0282] It can be understood that the embodiment here is only an example to illustrate that the electronic device 200 can include one or more temperature electrodes, and can also include one or more temperature detection elements. The embodiment of the present application does not limit the number of temperature electrodes and temperature detection elements in the electronic device 200.

[0283] The following describes a method for calculating the user's body temperature when the electronic device 200 has two temperature electrodes and two temperature detection elements.

[0284] The electronic device 200 may include a temperature electrode 1, a temperature electrode 2, a temperature detection element 1, and a temperature detection element 2. The measuring ends of the two temperature electrodes are located close to each other and are both set in the user's subcutaneous tissue. It can be considered that the temperatures of the measuring ends of the two temperature electrodes are both the user's body temperature T0. The temperature of the temperature detection element 1 can be T1, and the temperature of the temperature detection element 2 can be T2. A heat transfer path 1 can be formed from the measuring end of the temperature electrode 1 to the temperature detection element 1, and the thermal resistance of the heat transfer path 1 can be represented by R1. A heat transfer path 2 can be formed from the measuring end of the temperature electrode 2 to the temperature detection element 2, and the thermal resistance of the heat transfer path 2 can be represented by R2. By setting different wire lengths or using wires of different materials, the thermal resistance R1 of the heat transfer path 1 can be different from the thermal resistance R2 of the heat transfer path 2, that is, R2 ≠ R1. At the same time, the user's body temperature is a fixed value, and the heat obtained by the temperature electrode from the user's subcutaneous tissue and transferred to the temperature detection element can also be regarded as a fixed value q.

[0285] On heat transfer path 1, the temperature of the measuring end of temperature electrode 1 minus the heat loss on heat transfer path 1 is the temperature of temperature detection element 1. Similarly, on heat transfer path 2, the temperature of the measuring end of temperature electrode 2 minus the heat loss on heat transfer path 2 is the temperature of temperature detection element 2. Based on the above, the relationship between the temperature of the measuring end of temperature electrode 1 and the temperature of temperature detection element 1 can be referred to the following formula (1), and the relationship between the temperature of the measuring end of temperature electrode 2 and the temperature of temperature detection element 2 can be referred to the following formula (2). T0-T1=q*R1 (1) T0-T2=q*R2 (2)

[0286] According to formula (1) and formula (2), the following formula (3) can be obtained: T0 = (R2*T1-R1*T2) / (R2-R1) (3)

[0287] In formula (3), the temperature T1 of the temperature detection element 1 and the temperature T2 of the temperature detection element 2 can be measured by the temperature detection element. In addition, the thermal resistance R1 of the heat transfer path 1 and the thermal resistance R2 of the heat transfer path 2 can be values ​​pre-determined based on the material, length, and properties of the thermal conductive gel of the wire. Therefore, after obtaining the temperature T1 of the temperature detection element 1, the temperature T2 of the temperature detection element 2, the thermal resistance R1 of the heat transfer path 1, and the thermal resistance R2 of the heat transfer path 2, the electronic device 200 can calculate the user's body temperature T0 based on the above formula (3).

[0288] It is understandable that the above embodiment is only an illustrative introduction to a method of calculating the user's body temperature. In the embodiment of the present application, the electronic device 200 can also determine the user's body temperature based on a method different from the above embodiment, and the present application does not limit this.

[0289] S504. The electronic device 200 obtains physiological data.

[0290] The physiological data includes any one or more of current data, physiological parameter measurement values ​​and physiological parameter calibration values.

[0291] In one possible implementation, the electronic device 200 may receive and obtain the user's physiological data in response to the information 1 .

[0292] In another possible implementation, the electronic device 100 may also periodically acquire the user's physiological data, for example, periodically acquiring the user's physiological data at a fixed time interval of 1 (e.g., 5 minutes, 15 minutes, 1 hour, etc.), and recording the time at which the physiological data is acquired. It should be noted that the period at which the electronic device 100 acquires the user's physiological data may be the same as or different from the period at which the user's body temperature is acquired in step S503.

[0293] In the embodiment of the present application, the physiological data may include but is not limited to any one or more of the following: current data, physiological parameter measurement values, and physiological parameter calibration values.

[0294] The current data is described below.

[0295] The electronic device 200 can react with specific chemical substances (such as glucose, ketone bodies, uric acid, etc.) in the tissue fluid through electrochemical electrodes implanted in the user's subcutaneous tissue to generate a reaction current. The current data may include the size of the reaction current at one or more moments. Optionally, the current data may also include the correspondence between the reaction current and time.

[0296] It should be noted that if the electrochemical electrodes in the electronic device 200 are used to measure blood glucose, the current data includes the magnitude of the current generated by the reaction between the electrochemical electrodes and glucose, and optionally, the time at which the reaction current was measured. Similarly, if the electrochemical electrodes in the electronic device 200 are used to measure blood ketones, the current data includes the magnitude of the current generated by the reaction between the electrochemical electrodes and ketone bodies, and optionally, the time at which the reaction current was measured. If the electrochemical electrodes in the electronic device 200 are used to measure uric acid, the current data includes the magnitude of the current generated by the reaction between the electrochemical electrodes and uric acid, and optionally, the time at which the reaction current was measured.

[0297] It can be understood that the above embodiments are merely illustrative. When the physiological parameters measured by the electronic device 200 are different, the current data in the physiological data may include different sizes of reaction currents. In the embodiments of the present application, the electronic device 200 may also measure physiological parameters different from those in the above embodiments, and the reaction current included in the current data may also be different from that in the above embodiments. This application does not limit this.

[0298] In some embodiments, the current data may be represented by a current-time curve.

[0299] For example, FIG6B shows a schematic diagram of a current-time curve in the case of measuring blood glucose.

[0300] As shown in Figure 6B, in a two-dimensional coordinate system, the horizontal axis can represent time, and the vertical axis can represent the current measurement value. In this two-dimensional coordinate system, Curve I is the current-time curve, which is used to represent the relationship between the current measurement value and time. As shown in Figure 6B, during the time period represented by t0 to t1, the current tends to be stable; during the time period represented by t1 to t2, the current gradually increases.

[0301] It is understandable that the embodiment shown in FIG6B is only an example. In the embodiment of the present application, the measurement values ​​and current change trends obtained by the electronic device 200 may also be different from the embodiment shown in FIG6B above, and the present application does not limit this.

[0302] In some embodiments, electronic device 200 can be used to measure multiple physiological parameters. For example, electronic device 200 can be used to measure blood glucose and blood ketones. When electronic device 200 can measure blood glucose and blood ketones, current data can include the magnitude of the current generated by the electrochemical electrode's reaction with glucose, the magnitude of the current generated by the electrochemical electrode's reaction with ketone bodies, and optionally, the time at which the currents were measured.

[0303] In a possible implementation, when the electronic device 200 measures multiple physiological parameters, the current data may be represented by multiple current-time curves.

[0304] For example, FIG6C shows a schematic diagram of a current-time curve in the case of measuring blood glucose and blood ketones.

[0305] As shown in Figure 6C, in a two-dimensional coordinate system, the horizontal axis can represent time, and the vertical axis can represent current measurements. In this two-dimensional coordinate system, curve I1 is the current-time curve for current 1, which represents the relationship between the current measurement value generated by the electrochemical electrode's reaction with glucose and time. Curve I2 is the current-time curve for current 2, which represents the relationship between the current measurement value generated by the electrochemical electrode's reaction with ketone bodies and time.

[0306] It can be understood that the embodiment shown in Figure 6C is only an example. In the embodiment of the present application, the measurement values ​​obtained by the electronic device 200 and the current change trend may also be different from the embodiment shown in Figure 6C above, and the present application does not limit this.

[0307] It should be noted that the embodiment here is only an example of how the electronic device 200 can measure multiple physiological parameters at the same time. In the embodiment of the present application, the electronic device 200 can also measure more, fewer or different physiological parameters than the above embodiment, and the present application does not limit this.

[0308] The following introduces the physiological parameter measurement values ​​and physiological parameter calibration values.

[0309] In the embodiments of the present application, a measured physiological parameter value refers to the value of the physiological parameter determined based on the current data, that is, the value of the physiological parameter that has not been calibrated based on the user's body temperature. A calibrated physiological parameter value refers to the value of the physiological parameter determined based on the current data and the user's body temperature.

[0310] In some embodiments, the electronic device 200 may store one or more physiological parameter calculation models, which may determine physiological parameter measurement values ​​or physiological parameter calibration values ​​based on current data. Physiological parameter calculation models may include a Class A model and a Class B model. The Class A model is used to output the value of the user's physiological parameter at a preset body temperature based on the input current data; the Class B model is used to output the value of the user's physiological parameter at the current body temperature based on the input current data and the user's body temperature.

[0311] For example, FIG6D and FIG6E show input and output schematic diagrams of two physiological parameter calculation models provided in embodiments of the present application.

[0312] As shown in Figure 6D, physiological parameter calculation model F1 belongs to a Class A model. The input of this physiological parameter calculation model may include current data, and the output of the physiological parameter calculation model may include the value of the user's physiological parameter at a preset body temperature. According to physiological parameter calculation model F1, after obtaining the current data, the current data is used as the input of physiological parameter calculation model F1 to obtain the value of the user's physiological parameter at the preset body temperature. Because the user's actual body temperature may differ from the preset body temperature, the output value of the physiological parameter at this time may be a measured value of the physiological parameter, that is, a value of the physiological parameter that has not been calibrated for body temperature.

[0313] As shown in Figure 6E, physiological parameter calculation model F2 belongs to a Class B model. The input of this physiological parameter calculation model may include current data and the actual measured body temperature of the user, and the output of the physiological parameter calculation model may include the value of the user's physiological parameter at the actual body temperature. According to physiological parameter calculation model F2, after obtaining the current data and the user's actual body temperature, the current data and the actual body temperature are used as inputs to physiological parameter calculation model F2 to obtain the value of the user's physiological parameter at the actual body temperature. The output physiological parameter value in this case may be a calibrated physiological parameter value, that is, a physiological parameter value that has been calibrated for body temperature.

[0314] In some embodiments, the physiological parameter calculation model stored in the electronic device 200 may include a Class A model. In this case, the electronic device 200 may determine the physiological parameter measurement value through the Class A model based on the measured current data. In another possible implementation, the electronic device 200 may also store a current calibration model, the input of the current calibration model may include current data and user body temperature, and the output may include calibrated current data. In this case, the electronic device 200 may use the measured current data as the input of the current calibration model to obtain calibrated current data. And the calibrated current data is used as the input of the Class A model to obtain the physiological parameter calibration value.

[0315] In other embodiments, the physiological parameter calculation model stored in the electronic device 200 may further include a Class B model. In this case, the electronic device 200 may determine the physiological parameter calibration value through the Class B model based on the measured current data and the user's body temperature.

[0316] S505 . The electronic device 200 sends the physiological data to the electronic device 100 .

[0317] In one possible implementation, the electronic device 200 may receive and respond to the information 1 sent by the electronic device 100, and send physiological data to the electronic device 100. Optionally, the electronic device 200 may also send the user's body temperature to the electronic device 100.

[0318] In another possible implementation, the electronic device 200 may periodically send physiological data to the electronic device 100 at fixed time intervals as a sending period. Optionally, the electronic device 200 may also periodically send the user's body temperature to the electronic device 100.

[0319] S506. The electronic device 100 determines a physiological parameter calibration value of the user based on the physiological data.

[0320] In the case where the physiological data includes a physiological parameter calibration value, the electronic device 100 may acquire the physiological parameter calibration value from the physiological data.

[0321] When the physiological data includes physiological parameter measurements and the electronic device 100 receives the user's body temperature transmitted by the electronic device 200, the electronic device 100 may determine the physiological parameter calibration value based on the user's body temperature and the physiological parameter measurements using a temperature calibration model. The electronic device 100 may store one or more temperature calibration models. The input of the temperature calibration model may include the user's body temperature and the physiological parameter measurements, and the output of the temperature calibration model may include the physiological parameter calibration value.

[0322] In the case where the physiological data includes current data, and the electronic device 100 receives the user's body temperature sent by the electronic device 200, the electronic device 100 can determine the user's physiological parameter calibration value through the physiological parameter calculation model based on the current data and the user's body temperature. The specific determination method can refer to the relevant content in the above step S504, which will not be repeated here. It should be noted that in this case, the electronic device 100 can store one or more physiological parameter calculation models, and the one or more physiological parameter calculation models can include Class A models and / or Class B models. Optionally, the electronic device 100 can also store one or more temperature calibration models, or store one or more current calibration models. The functional description of the temperature calibration model and the current calibration model can refer to the relevant content in the above embodiment, which will not be repeated here.

[0323] S507. The electronic device 100 outputs the user's physiological parameter calibration value.

[0324] In some embodiments, after determining the user's physiological parameter calibration value, the electronic device 100 may output the physiological parameter calibration value. The electronic device 100 may output the physiological parameter calibration value in a manner including, but not limited to, any one or more of the following: display screen display, voice announcement, vibration, flashing indicator light, etc. For a schematic diagram of the interface for outputting the physiological parameter calibration value by the electronic device 100, reference may be made to the description of the embodiments shown in Figures 7C to 7F below, and will not be described in detail here.

[0325] In some embodiments, the electronic device 100 may output any one or more of the following while outputting the physiological parameter calibration value of the user (or after outputting the physiological parameter calibration value): evaluation results, value range, user status, historical curve, reference suggestions, etc. Among them, the evaluation results are used to characterize whether the user's physiological parameters are normal. The value range refers to the normal range of the user's physiological parameters. The user status refers to the user's current state, such as fasting state, non-fasting state, exercise state, high altitude state, sleeping state, etc. The historical curve is used to characterize the relationship between the user's physiological parameters and time in the past period of time (for example, 30 minutes, 3 hours, 24 hours, etc.). Reference suggestions can be used to guide users to maintain or restore physiological parameters to the normal range.

[0326] In other embodiments, after determining the user's physiological parameter calibration value, the electronic device 100 may also send an output instruction to another electronic device. The output instruction may include the user's physiological parameter calibration value, and the output instruction may be used to instruct the electronic device to output the user's physiological parameter calibration value. Optionally, the output instruction may also include, but is not limited to, any one or more of the following: user status, value range, evaluation results, historical curve, reference suggestions, etc. The electronic device 100 may output any one or more of the above content based on the output instruction.

[0327] The following describes how to determine the evaluation results, value range, user status, historical curves, and reference suggestions.

[0328] The following describes how the user status is determined.

[0329] In some embodiments, the electronic device 100 can determine the user status based on the user information. The specific content of the user information can refer to the relevant description in the above step S501, which will not be repeated here. For example, the electronic device 100 can receive and determine the user status in response to the user's operation of setting the user status. For another example, the electronic device 100 can determine whether the user is in a motion state based on the user's motion information. For another example, the electronic device 100 can determine whether the user is in a high altitude state based on the user's location information, etc. It can be understood that the embodiment here is only an illustrative example of how the electronic device 100 can determine the user status based on the user information. In the embodiment of the present application, the electronic device 100 can also determine the user status based on other information in the user information, and the present application does not limit it here.

[0330] The following describes how to determine the value range.

[0331] The value interval may be the value interval of the physiological parameter stored in the electronic device 100. For example, Table 1 shows the value interval of the physiological parameter stored in the electronic device 100 provided in an embodiment of the present application.

[0332] Table 1

[0333] As shown in Table 1, the electronic device 100 may store value ranges for one or more physiological parameters. For example, the value range for blood glucose may be [3.9, 6.1], the value range for blood ketones may be [0.05, 0.3], and the value range for uric acid may be [0.18, 0.42]. The units of the above value ranges are all millimoles per liter (mmol / L).

[0334] It can be understood that the embodiment shown in Table 1 is only an example. In the embodiment of the present application, the electronic device 100 can also store more, fewer or different value ranges of physiological parameters than the embodiment shown in Table 1, and the value range of the physiological parameters can also be different from the above value ranges. This application does not limit this.

[0335] In other embodiments, the electronic device 100 may also store value ranges of physiological parameters under different user states. For example, Table 2 shows value ranges of physiological parameters under different user states stored in another electronic device 100 provided in an embodiment of the present application.

[0336] Table 2

[0337] As shown in Table 2, the electronic device 100 may store value ranges for one or more physiological parameters in different user states. For example, in the fasting state, the blood glucose value range may be [3.9, 6.1]; in the non-fasting state, the blood glucose value range may be [3.9, 8.99]; in the fasting state, the blood ketone value range may be [0.05, 0.3]; in the non-fasting state, the blood ketone value range may be [0.05, 0.5]; in the fasting state, the uric acid value range may be [0.18, 0.42]; in the non-fasting state, the uric acid value range may be [0.18, 0.5]. The unit of the above value ranges is millimole / liter (mmol / L).

[0338] It is understandable that the embodiment shown in Table 2 is only an example. In the embodiment of the present application, the electronic device 100 may also store more, fewer, or different value intervals of physiological parameters than the embodiment shown in Table 2, and the value intervals of the physiological parameters may also be different from the above value intervals. This application does not limit this. In addition, the user status may also include more, fewer, or different user status than the above embodiment. Moreover, in other embodiments, the electronic device 100 may also store the correspondence between factors such as user gender, age, and disease and the value interval, which is not limited in this application.

[0339] The electronic device 100 may determine the value range based on any one or more factors such as user status, user age, gender, etc.

[0340] The following describes how the evaluation results are determined.

[0341] In one possible implementation, the electronic device 100 may store the value ranges of the user's physiological parameters and determine the evaluation result based on the user's physiological parameter calibration values ​​and the corresponding physiological parameter value ranges. In another possible implementation, the electronic device 100 may also determine the user's current physiological parameter value range based on the correspondence between one or more factors such as the user's gender, age, and user status and the value ranges, and determine the evaluation result based on the physiological parameter calibration values.

[0342] In some embodiments, the evaluation results may include normal and abnormal. When the physiological parameter calibration value falls within the value interval, the electronic device 100 may determine that the evaluation result is normal for the physiological parameter. When the physiological parameter calibration value does not fall within the value interval, the electronic device 100 may determine that the evaluation result is abnormal for the physiological parameter. Optionally, in the case where the evaluation result is abnormal, the evaluation result may be further subdivided into any one or more of the following: high, low, too high, too low, etc., which is not limited in this application.

[0343] In some embodiments, if the evaluation result is determined to be abnormal (or the evaluation result is determined to be abnormally high or too low, etc.), the electronic device 100 can output a warning. The output method of the warning may include but is not limited to any one or more of the following: display screen display, voice broadcast, vibration, flashing indicator light, etc.

[0344] The following describes how to determine the historical curve.

[0345] In some embodiments, the electronic device 100 may determine a historical curve of the physiological parameter based on the currently measured physiological parameter calibration value. In other embodiments, the electronic device 100 may also determine a historical curve of the physiological parameter based on the currently measured physiological parameter calibration value and previously measured physiological parameter calibration values. The electronic device 100 may store the measurement time of each physiological parameter calibration value, and the electronic device 100 may determine a historical curve of the physiological parameter based on different calibration values ​​corresponding to different measurement times.

[0346] The following describes how reference recommendations are determined.

[0347] In one possible implementation, the electronic device 100 may determine a reference recommendation based on the evaluation result. For example, if the evaluation result is normal, the reference recommendation may be to advise the user to maintain their current lifestyle habits, or to increase exercise and maintain a good sleep and rest schedule. If the evaluation result is abnormal, the reference recommendation may be to advise the user to correct unhealthy lifestyle habits, reduce the intake of greasy foods, etc.

[0348] In another possible implementation, the electronic device 100 may also determine reference suggestions based on user information. For example, when the electronic device 100 determines based on user information that the user is in a high-altitude area, the reference suggestion may include "The oxygen in the current area is thin, so be careful to reduce strenuous exercise." For another example, when the electronic device 100 determines based on user information that the user has been in a fasting state for a duration greater than a certain period (such as 4 hours), the reference suggestion may include "You are currently hungry, please eat as soon as possible," etc. It will be understood that the embodiment here is merely an illustrative example of how the electronic device 100 can determine reference suggestions based on user information. In the embodiment of the present application, the electronic device 100 may also determine content different from the above-mentioned reference suggestions based on user information, and the present application does not limit this.

[0349] By adopting the detection method provided in the embodiment of the present application, physiological parameters can be calibrated in combination with the user's real-time body temperature, thereby avoiding the influence of body temperature on the measurement results and improving the accuracy of the measurement results.

[0350] The following describes a measurement method provided in an embodiment of the present application in conjunction with a specific application scenario.

[0351] In some application scenarios, the electronic device 200 may be a CGM device for obtaining physiological data related to the user's blood sugar (current data, blood sugar measurement values ​​or blood sugar calibration values, etc.).

[0352] For example, as shown in FIG7A , the electronic device 100 displays a health application interface 700 , which may include one or more items, such as a blood sugar item 701 , a blood pressure item, a heart rate item, a blood oxygen item, etc. Each item may be used to trigger the electronic device 100 to display a corresponding physiological parameter measurement interface.

[0353] The electronic device 100 may receive and, in response to a user's click operation on the blood glucose entry 701 , display a blood glucose measurement interface 710 as shown in FIG. 7B .

[0354] As shown in Figure 7B, the blood glucose measurement interface 710 may include a measurement control 711 and a history control 712. The measurement control 711 may be used to trigger the electronic device 100 to determine and output the user's blood glucose, and the history control 712 may be used to trigger the electronic device 100 to display past blood glucose measurement records (including the measurement time and the user's blood glucose).

[0355] The electronic device 100 can receive and respond to the user's click operation on the measurement control 711, obtain the user's body temperature and physiological data (such as current data and / or blood glucose measurement value) sent by the electronic device 200, and after determining the user's blood glucose (i.e., blood glucose calibration value) based on the user's body temperature and physiological data, the electronic device 100 can display the output interface 720 as shown in Figure 7C.

[0356] As shown in Figure 7C, output interface 720 may include blood glucose 721, which may be the user's calibrated blood glucose value. Optionally, 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 history curve control 725. Evaluation result 722 may indicate whether the user's blood glucose is normal. As shown in Figure 7C, evaluation result 722 is a horizontal line, indicating that the user's calibrated blood glucose value falls within a preset value range, i.e., the user's blood glucose is normal. In some embodiments, if the user's calibrated blood glucose value is greater than the preset value range, the evaluation result may also be an upward arrow, and if the user's calibrated blood glucose value is less than the preset value range, the evaluation result may also be a downward arrow. It should be understood that the display method of evaluation result 722 shown in Figure 7C is merely an example. In the embodiments of this application, the evaluation result may also be represented by different symbols, text, etc., and this application is not limited thereto. Value range 723 represents the reference range of the user's blood glucose, i.e., the normal range of blood glucose values ​​for the user in the current user state. User status 724 may be used to indicate the user's current status, such as whether they are fasting. In some embodiments, the value interval 723 may also be different depending on the user's status. History curve control 725 may be used to trigger the electronic device 100 to display a history curve of blood glucose, which is used to represent the relationship between the user's blood glucose calibration value and time over a period of time.

[0357] The electronic device 100 may receive and respond to a user click operation on the history curve control 725, and display the history curve interface 730 shown in FIG7D . Alternatively, the electronic device 100 may also receive and respond to a user swipe-up operation on the output interface 720, and display the history curve and other content shown in FIG7D on the output interface 720.

[0358] As shown in Figure 7D, the historical curve interface 730 may include a historical curve 731, and optionally, may further include a reference suggestion 732. The historical curve 731 can be used to characterize the relationship between the user's blood glucose calibration value and time over the past period of time. The reference suggestion 732 can be used to guide the user to maintain or restore blood glucose to a normal range. For example, the reference suggestion 732 may include the text "blood glucose is stable, please maintain". It will be understood that the reference suggestion 732 shown in Figure 7D is only an example. In the embodiment of the present application, the reference suggestion 732 may also adopt an output form different from the above-mentioned embodiment, and may also include more, less or different content than the above-mentioned embodiment, and the present application does not limit it here.

[0359] In other embodiments, the electronic device 100 can receive and respond to the user's click operation on the measurement control 711, obtain the user's body temperature and physiological data sent by the electronic device 200, and after determining the user's blood sugar (i.e., blood sugar calibration value) based on the user's body temperature and physiological data, if the user's blood sugar is abnormal, optionally, the electronic device 100 can display a warning interface 740 as shown in Figure 7E, or display an output interface 750 as shown in Figure 7F.

[0360] As shown in FIG7E , warning interface 740 may include a warning 741 and, optionally, a view result control 742. Warning 741 may be used to inform the user of abnormal blood sugar levels. For example, warning 741 may include the text "Low blood sugar, please eat soon!!" View result control 742 may be used to trigger electronic device 100 to display the blood sugar calibration value.

[0361] The electronic device 100 may receive and display an output interface 750 as shown in FIG7F in response to a user clicking operation on the view result control 742. In some embodiments, the electronic device 100 may also display an output interface 750 as shown in FIG7F when it detects that the display duration of the warning interface 740 is greater than a preset duration (e.g., 10 seconds, 15 seconds, etc.).

[0362] As shown in Figure 7F, output interface 750 may include blood glucose 751, which may be the user's calibrated blood glucose value. Optionally, output interface 750 may also include, but is not limited to, any one or more of the following: an evaluation result 752, a value range 753, a user status 754, and reference suggestions 755. Evaluation result 752 may indicate whether the user's blood glucose is normal. As shown in Figure 7F, evaluation result 752 is a downward arrow, indicating that the user's calibrated blood glucose value is less than a preset value range, meaning that the user's blood glucose is abnormal. Value range 753 represents the user's blood glucose reference range, i.e., the range of blood glucose values ​​that indicate a healthy user. User status 754 may indicate the user's current state, such as whether they are fasting. In some embodiments, value range 753 may vary depending on the user's state. Output interface 750 may also include reference suggestions 755, which may, for example, include the text "Low blood glucose, please eat soon!" It is understandable that in other embodiments, the output interface 750 may also display a historical curve of blood glucose (or a historical curve control), etc. The historical curve is used to characterize the relationship between the user's blood glucose calibration value and time over the past period of time, and this application does not limit this.

[0363] It can be understood that the embodiments shown in Figures 7A to 7F above are just two examples. In the embodiments of the present application, the output physiological parameters may also be other physiological parameters (such as blood ketones, uric acid, etc.), and the device that outputs the physiological parameter calibration value may also be a mobile phone or other electronic device, and the content displayed in the output interface may also include more, less or different content from the above embodiments, and the present application does not limit this.

[0364] The following introduces the functional modules of a measurement system 10 provided in an embodiment of the present application.

[0365] FIG8 shows a schematic diagram of functional modules of a measurement system 10 provided in an embodiment of the present application.

[0366] As shown in FIG8 , the measurement system 10 may include an electronic device 100 and an electronic device 200 .

In some embodiments, the user information module 1004 can also determine whether the user information meets the monitoring conditions. If the monitoring conditions are met, the user information module 1004 can send a message Q2 to the communication module 1002. The message Q2 can be used to instruct the communication module 1002 to send information 1 to the electronic device 200.

[0371] The evaluation module 1005 may store a value interval of a physiological parameter. The evaluation module 1005 may determine an evaluation result based on the value interval of the physiological parameter and the calibrated value of the physiological parameter, and the evaluation result is used to indicate whether the physiological parameter is normal. In some embodiments, the evaluation module 1005 may also receive the user status sent by the user information module 1004, and determine the evaluation result based on the relationship between the user status and the value interval of the physiological parameter, and the calibrated value of the physiological parameter. In other embodiments, the evaluation module 1005 may also determine a reference suggestion based on the user status and / or the evaluation result, and the reference suggestion is used to guide the user to maintain (or restore to) a normal range for the physiological parameter. The evaluation module 1005 may send the evaluation result and / or the reference suggestion to the output module 1006, or send it to other electronic devices through the communication module 1002.

[0372] The output module 1006 can receive and output the physiological parameter calibration values ​​sent by the data processing module 1003, and can also receive and output the evaluation results and / or reference suggestions sent by the evaluation module 1005, etc.

[0373] In electronic device 200, communication module 2001 can communicate with electronic device 100. In some embodiments, communication module 2001 can receive and, in response to information 1 sent by communication module 1002, send acquisition information 1 to measurement module 2002 and send acquisition information 2 to temperature module 2003. Acquisition information 1 is used to request physiological data, and acquisition information 2 is used to request the user's body temperature. In other embodiments, communication module 2001 can send physiological data and user body temperature to communication module 1002 at fixed time intervals.

[0374] The measurement module 2002 can acquire physiological data. In some embodiments, after receiving the acquisition information 1 sent by the communication module 1002, the measurement module 2002 can send the acquired physiological data to the communication module 2001. In other embodiments, the measurement module 2002 can also acquire physiological data at fixed time intervals and send the physiological data to the communication module 2001 at fixed time intervals.

[0377] It can be understood that the embodiment shown in Figure 8 is only an example. In the embodiment of the present application, the measurement system 10 may include more, fewer or different functional modules than the above embodiment, or the above multiple functional modules may be combined into one functional module, or any of the above functional modules may be split into multiple functional modules. This application does not limit this.

[0379] For the convenience of subsequent description, the above-mentioned electronic device 100 and electronic device 200 can be collectively referred to as devices. It should be understood that the division of the various units in the device is only a division of logical functions. In actual implementation, they can be fully or partially integrated into one physical entity, or they can be physically separated. In addition, the units in the device can be implemented in the form of a processor calling software; for example, the device includes a processor, the processor is connected to a memory, the memory stores instructions, and the processor calls the instructions stored in the memory to implement any of the above methods or implement the functions of the various units of the device, wherein the processor is, for example, a general-purpose processor, such as a central processing unit (CPU) or a microprocessor, and the memory is a memory within the device or a memory outside the device. Alternatively, the units in the device can be implemented in the form of hardware circuits, and the functions of some or all of the units can be realized by designing the hardware circuits. The hardware circuit can be understood as one or more processors. For example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC), which realizes the functions of some or all of the above units by designing the logical relationship of the components in the circuit. For another example, in another implementation, the hardware circuit can be implemented by a programmable logic device (PLD). Taking a field programmable gate array (FPGA) as an example, it can include a large number of logic gate circuits, and the connection relationship between the logic gate circuits is configured by configuring the configuration file, thereby realizing the functions of some or all of the above units. All units of the above devices can be implemented in the form of software called by the processor, or in the form of hardware circuits, or in part by software called by the processor, and the rest by hardware circuits.

[0380] In an embodiment of the present application, a processor is a circuit with data processing capabilities. In one implementation, the processor can be a circuit with instruction reading and execution capabilities, such as a CPU, a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP); in another implementation, the processor can implement certain functions through the logical relationship of a hardware circuit, and the logical relationship of the hardware circuit is fixed or reconfigurable, such as a hardware circuit implemented by an ASIC or PLD, such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and implementing the hardware circuit configuration can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units. In addition, 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), a tensor processing unit (TPU), a deep learning processing unit (DPU), etc.

[0381] It can be seen that each unit in the above device can be one or more processors (or processing circuits) configured to implement the above method, such as: CPU, GPU, NPU, TPU, DPU, microprocessor, DSP, ASIC, FPGA, or a combination of at least two of these processor forms.

[0382] In addition, the various units in the above devices can be fully or partially integrated together, or can be implemented independently. In one implementation, these units are integrated together and implemented in the form of a system-on-a-chip (SOC). The SOC may include at least one processor for implementing any of the above methods or implementing the functions of the various units of the device. The type of the at least one processor can be different, for example, including a CPU and FPGA, a CPU and an artificial intelligence processor, a CPU and a GPU, etc.

When implemented in hardware, the processor may be a logic circuit, an integrated circuit, etc. When implemented in software, the processor may be a general-purpose processor implemented by reading software code stored in a memory.

[0398] Optionally, the memory in the chip system may be one or more.

[0400] It can be understood that the above chip system is only an example. In the embodiments of the present application, the chip system may also include more, fewer or different devices than the above embodiments, and the present application does not limit this.

[0401] 10-11 show schematic flow charts of two measurement methods provided in embodiments of the present application.

[0402] As shown in FIG10 , the specific process of the measurement method may include the following steps:

[0403] S1001. When part of the first temperature electrode and part of the first electrochemical electrode are implanted into subcutaneous tissue, the first electronic device detects the first temperature on the first temperature electrode through the first temperature detection element; wherein, the first electronic device includes a first temperature detection element and a first sensor, the first sensor includes a first temperature electrode and a first electrochemical electrode, and the first temperature detection element is connected to the first temperature electrode.

[0404] The first electronic device may be the electronic device 200 in the above embodiment.

The first temperature electrode may be the temperature electrode 1 in the above embodiment, the first electrochemical electrode may be the working electrode in the above embodiment, and the first temperature detection element may be the temperature detection element 305 in the above embodiment.

[0406] The first temperature may be used to determine the user's body temperature.

[0407] In a possible implementation, the first temperature is the temperature of the first conducting end.

[0408] In some embodiments, the first temperature may be considered the user's body temperature.

[0409] The manner in which the first electronic device determines the first temperature and the manner in which the user's body temperature is determined based on the first temperature may refer to the relevant description in step S503 shown in FIG. 5 above, and will not be repeated here.

[0412] In a possible implementation, the heat of the subcutaneous tissue is conducted to the first temperature detection element through the first measuring end, the first wire, and the first conducting end.

[0413] In this way, the heat of the subcutaneous tissue can be obtained through the first measuring end of the first temperature electrode, and the heat can be conducted to the first temperature detection element through the first temperature electrode, and the first temperature detection element determines the first temperature of the first temperature electrode based on the heat.
