Description

Technical Field

[0001] This invention relates to smart electronic bracelets, and more particularly to a smart electronic bracelet that can detect a user's vital signs through pressure, including physiological indicators such as blood pressure and pulse, as well as a method for measuring the user's vital signs using the smart electronic bracelet. Background Technology

[0002] With the development of technology, smartphones are widely used in users' daily lives. Users can improve the convenience of life through their various functions, such as mobile payment and recording vital signs in daily life. However, some situations in daily life are not conducive to users carrying smartphones to perform the above functions. For example, during exercise, the weight and size of smartphones are not conducive to users carrying them, which makes it impossible for users to record their vital signs during exercise.

[0003] Therefore, the invention of wearable smart devices was prompted, allowing users to perform some of the functions of a smartphone in specific situations. For example, because an electronic bracelet (wearable smart device) is lighter and smaller than a smartphone, it allows users to wear it for extended periods of time. Compared to a smartphone, the electronic bracelet can record the user's daily physiological data more comprehensively.

[0004] However, due to the limited size of the electronic bracelet, the space for setting up the physiological data sensor is also limited, which in turn limits the types of physiological data sensors. For example, most electronic bracelets currently rely on optical principles to achieve their functions. An optical sensor is set on the inner surface of the existing electronic bracelet. When the user wears the electronic bracelet, the optical sensor will be in contact with the user's skin to sense the light intensity signal reflected by the user's blood through optical principles. Then, the processing device in the electronic bracelet will calculate pulse data, blood pressure data, body temperature data, etc. from the light intensity signal. However, the accuracy of some data (such as pulse and blood pressure data) will be questionable because multiple physiological data are calculated from only the light intensity signal. Therefore, it is necessary to propose an improvement scheme to improve the accuracy of such physiological data measurement. Summary of the Invention

[0005] Existing electronic bracelets typically use optical sensing principles to obtain users' physiological data, which leads to concerns about the accuracy of some of the physiological data. In view of this, the present invention proposes a pressure-sensitive smart electronic bracelet and its application method, which uses physical sensing technology, namely pressure detection, to improve the accuracy of obtaining and measuring physiological data such as blood pressure and pulse.

[0006] This invention relates to a pressure-sensitive smart electronic bracelet, comprising:

[0007] The first subject includes:

[0008] A first housing has a first side and a second side opposite to each other, the first side being connected to a wristband, and the first housing having a first receiving space inside;

[0009] An air pump is installed in the first accommodating space;

[0010] A second subject, comprising:

[0011] A second outer casing is connected to a second side of the first outer casing, and the second outer casing has a second accommodating space inside;

[0012] A control circuit board is disposed in the second accommodating space, the control circuit board having a first surface and a second surface opposite to each other;

[0013] Multiple pressure sensing groups, each pressure sensing group including multiple pressure sensors, the multiple pressure sensors being disposed on a first surface of the control circuit board, and each pressure sensor being electrically connected to the control circuit board and having a contact portion, each contact portion being exposed on the outer surface of the second housing, each pressure sensor sensing the user's pulse to generate a pressure sensing signal.

[0014] An airbag is disposed in the second accommodating space, and the airbag is located between the second surface of the control circuit board and the second housing and connected to the inflation pump.

[0015] One application method of the pressure-sensitive smart electronic bracelet of the present invention is applied to the pressure-sensitive smart electronic bracelet as described above, wherein...

[0016] When the pressure-sensitive smart electronic bracelet is worn on a user's wrist, the air pump of the pressure-sensitive smart electronic bracelet inflates the airbag according to the user's operation;

[0017] When the air pump stops operating and the airbag deflates, the control circuit board receives the pressure sensing signals transmitted by each pressure sensor and performs multiple signal processing steps on each pressure sensing signal to obtain a pulse amplitude signal. The pulse amplitude signal is then transmitted to an AI server, which performs deep analysis and calculation to extract multiple feature point information.

[0018] Among them, the multiple feature point information includes systolic blood pressure information and diastolic blood pressure information.

[0019] Another application method of the pressure-sensitive smart electronic bracelet of the present invention is applied to the pressure-sensitive smart electronic bracelet as described above, wherein...

[0020] When the pressure-sensitive smart electronic bracelet is worn on a user's wrist, the air pump of the pressure-sensitive smart electronic bracelet inflates the airbag according to the user's operation;

[0021] When the inflation pump stops operating and the airbag deflates, the control circuit board receives the pressure sensing signals transmitted by each pressure sensor and performs multiple signal processing steps on each pressure sensing signal to obtain a pulse wave signal. Then, it performs a Fourier transform on the pulse wave signal to obtain a high-frequency signal and a low-frequency signal. Finally, it transmits the pulse wave signal, the high-frequency signal, and the low-frequency signal to an AI server. The AI ​​server performs deep analysis and calculations to extract multiple feature waveform information.

[0022] This invention relates to a pressure-sensitive smart electronic bracelet comprising a first body and a second body. Compared to the electronic bracelets described in the prior art, it increases the space for physical sensors, thus allowing for unrestricted measurement of the types of physiological data. When a user wears the pressure-sensitive smart electronic bracelet, each pressure sensor transmits the user's pulse through the contact portion to generate a pressure sensing signal. Furthermore, when the airbag inflates, each contact portion protrudes further from the second shell, increasing the contact area and the degree of contact with the user's skin. Compared to the prior art, which senses pulse data through optical principles, where the transmitting (or receiving) end of the optical sensor may be obstructed by external objects, leading to inaccurate pulse data, this invention's pressure-sensitive smart electronic bracelet, by measuring the user's pulse data through contact conduction, effectively improves the accuracy of obtaining and measuring physiological data such as blood pressure and pulse.

[0023] This pressure-sensitive smart electronic bracelet features unique physical sensing technology, enabling it to instantly detect the user's vital signs, including physiological indicators such as blood pressure and pulse. The bracelet transmits this data to an AI server, where it undergoes in-depth analysis and computation to generate multiple analytical results. These results are fed back to the user and simultaneously provided to relevant medical institutions, allowing healthcare professionals to quickly understand the user's physiological state and provide effective medical treatment and recommendations.

[0038] To gain a detailed understanding of the technical features and practical effects of the present invention, and to enable its implementation according to the invention, the following detailed description is provided with reference to the embodiments shown in the figures:

[0039] See also Figures 1 to 3The pressure-sensitive smart electronic bracelet 1 of the present invention includes a first body 10, a second body 20, and a bracelet strap 30. The first body 10 is connected to the second body 20 and the bracelet strap 30 respectively. Specifically, the second body 20 and the bracelet strap 30 are respectively connected to opposite sides of the first body 10, and the bracelet strap 30 is detachably attached to the second body 20. When the bracelet strap 30 is connected to the second body 20, the pressure-sensitive smart electronic bracelet 1 will function as follows: Figure 3 It is shown in a ring shape and can be worn by the user.

[0040] The first main body 10 includes a first outer shell 11 and an air pump 12. The first outer shell 11 has a first side and a second side opposite to each other. The first side is connected to the wristband 30, and the second side is connected to the second main body 20. The first outer shell 11 has a first accommodating space (not shown). The air pump 12 is disposed in the first accommodating space. Specifically, a channel 13 is formed on the first outer shell 11. The channel 13 connects the first accommodating space and the outside of the first outer shell 11. When the air pump 12 is operating, it can draw gas from the outside of the first outer shell 11 through the channel 13 to inflate it.

[0041] In one embodiment of the present invention, the first body 10 further includes at least one button 14, a screen 15, an optical sensor 16 and a first controller, wherein the first controller is electrically connected to the at least one button 14, the screen 15, the optical sensor 16 and the air pump 12 respectively.

[0042] At least one button 14 is disposed on the outer surface of the first housing 11. This button 14 is operated by the user to perform the functions of the pressure-sensitive smart electronic bracelet 1, such as pressing the button 14 to activate the air pump 12. The screen 15 is disposed in the first accommodating space, with one display surface of the screen 15 exposed on the outer surface of the first housing 11. Preferably, the screen 15 is a touch display screen, and such as... Figure 3 As shown, when the pressure-sensitive smart electronic bracelet 1 is worn on a user's wrist W, the surface of the first outer shell 11 that contacts the user is defined as a user contact surface 110. The screen 15 is exposed on the outer surface opposite to the user contact surface 110, so the user can touch to perform the functions of the pressure-sensitive smart electronic bracelet 1. For example, in addition to starting the air pump 12 by the at least one button 14, the user can also start the air pump 12 by touching the screen 15.

[0043] The optical sensor 16 is disposed in the first accommodating space, and a detection surface of the optical sensor 16 is exposed on the outer surface of the first housing 11. Specifically, the detection surface of the optical sensor 16 is exposed on the user contact surface 110. The optical sensor 16 emits light and receives reflected light through the detection surface to detect the user's physiological data. The first controller is disposed in the first accommodating space. For example, the first controller is a microcontroller (MCU).

[0044] The second main body 20 includes a second outer shell 21, a control circuit board 22, an airbag 23, and multiple pressure sensor groups. The second outer shell 21 is connected to the second side of the first outer shell 11. Preferably, the connection between the second outer shell 21 and the first outer shell 11 is pivotal. Please refer to [reference needed]. Figure 4 and Figure 5 The second outer shell 21 has a second accommodating space 210 inside, the control circuit board 22 is disposed in the second accommodating space 210, and the control circuit board 22 has a first surface 220 and a second surface 221 opposite to each other, the airbag 23 is disposed in the second accommodating space 210, and the airbag 23 is located between the second surface 221 of the control circuit board 22 and the second outer shell 21, the airbag 23 is connected to the air pump 12 and can change its size according to the opening and closing state of the air pump 12.

[0045] For example, such as Figure 1 and Figure 2 As shown, the airbag 23 is connected to the inflation pump 12 via a pipeline 230. When the inflation pump 12 is started, the gas drawn into the inflation pump 12 from the channel 13 will fill the airbag 23 through the pipeline 230, and the airbag 23 will inflate as a result. When the inflation pump 12 is turned off after running for a period of time, the gas in the airbag 23 will be discharged from the inflation pump 12 or the channel 13 through the pipeline 230, and the airbag 23 will return to its uninflated state.

[0046] Each pressure sensing group includes a plurality of pressure sensors 24 disposed on the first surface 220 of the control circuit board 22. Specifically, as Figures 3 to 5 As shown, the outer surface of the second housing 21 includes an inner surface 211 and an outer surface 212. Each pressure sensor 24 includes a contact portion 240 and a sensor body 241. The inner surface 211 exposes each contact portion 240, and each contact portion 240 is connected to each sensor body 241. A loop fixing portion 25 is provided on the outer surface 212. The loop fixing portion 25 allows the wristband 30 to be detachably connected. For example, the loop fixing portion 25 is a watchband buckle, through which the wristband 30 can pass and be fastened to the watchband buckle to connect to the second body 20.

[0047] When the pressure-sensitive smart electronic bracelet 1 is worn on the user's wrist W, each of the contact portions 240 contacts the surface of the wrist W, and the contact area between each contact portion 240 and the user can increase or decrease according to the size of the airbag 23. When the airbag 23 is inflated, the control circuit board 22 will be moved by the pressure of the airbag 23, thereby pushing the contact portion 240 further out of the second receiving space 210 (e.g., Figure 5 As shown, the area of ​​the contact portion 240 exposed on the inner surface 211 will increase, the contact area between each contact portion 240 and the user will increase, and because each contact portion 240 is pushed by the airbag 23, it can fit more closely to the surface of the wrist W.

[0048] See also Figure 6 Each pressure sensor 24 is electrically connected to the control circuit board 22, and each pressure sensor 24 is used to sense the user's pulse to generate a pressure sensing signal S1. Specifically, the control circuit board 22 is provided with a second controller 26, which may also be a microcontroller. The second controller 26 is electrically connected to each pressure sensor 24. Preferably, the second controller 26 is electrically connected to the sensor body 241 of each pressure sensor 24. The user's pulse can be transmitted to each sensor body 241 through each contact portion 240. Each sensor body 241 will transmit an analog signal to the second controller 26. The analog signal is the pressure sensing signal S1. It should be noted that when each of the contact portions 240 is pushed more tightly against the surface of the wrist W by the airbag 23, the signal strength of the pressure sensing signal S1 generated by each pressure sensor 24 will be enhanced (compared to the state when the airbag 23 is not inflated).

[0049] In one embodiment of the present invention, the plurality of pressure sensors 24 are divided into a plurality of first pressure sensors and a plurality of second pressure sensors. Each of the first pressure sensors transmits a first pressure sensing signal to the control circuit board 22, and each of the second pressure sensors transmits a second pressure sensing signal to the control circuit board 22. That is, each pressure sensing group transmits the first pressure sensing signal and the second pressure sensing signal to the control circuit board 22 (second controller 26) respectively. The control circuit board (second controller 26) calculates the difference between each of the first pressure sensing signals and each of the second pressure sensing signals to generate a plurality of pressure processing signals.

[0050] Specifically, each pressure sensing group includes a first pressure sensor and a second pressure sensor. The contact portions of the first pressure sensor and the second pressure sensor are located on opposite sides of the inner surface 211. When the user wears the pressure-sensitive smart electronic bracelet 1, at least one of the multiple pressure sensing groups can correspond to the user's arterial position, and the contact portions of the first and second pressure sensors of the pressure sensing group can also correspond to the user's arterial position.

[0051] The second controller 26 uses the signal with the smaller waveform amplitude of the first and second pressure sensing signals from the pressure sensing group as a reference signal, and subtracts the reference signal from the other signal to generate a pressure processing signal. For example, if the waveform amplitude of the first pressure sensing signal of one of the pressure sensing groups is smaller, the second controller 26 uses the first pressure sensing signal as the reference signal, and subtracts the first pressure sensing signal from the second pressure sensing signal of the pressure sensing group to generate the pressure processing signal. The second controller 26 will also calculate the pressure processing signal for the other first and second pressure sensing signals transmitted by pressure sensing groups that do not correspond to the user's artery in the same way. The difference is that the signal value of the pressure processing signal of the pressure sensing group corresponding to the user's artery is not zero, and the signal value of the pressure processing signal of the pressure sensing group that does not correspond to the user's artery is zero.

[0052] In one embodiment of the present invention, such as Figure 6 As shown, the second controller 26 is connected to the first controller 17 and a pressure sensor 27. The pressure sensor 27 is disposed in the second accommodating space 210. The pressure sensor 27 is used to sense the air pressure inside the airbag 23 to generate a pressure measurement signal S2 to the second controller 26. The second controller 26 transmits the pressure sensor 27 to the first controller 17, causing the first controller 17 to control the inflation pump 12 to shut down based on the pressure measurement signal S2. For example, the first controller 17 has a preset air pressure threshold value. The first controller 17 determines whether the air pressure inside the airbag 23 is greater than the air pressure threshold value based on the pressure measurement signal S2. If it is, it means that the airbag 23 is full of gas, and the first controller 17 controls the inflation pump 12 to shut down to stop inflating the airbag 23.

[0053] In this embodiment, the control circuit board 22 is further provided with at least one of a Bluetooth Low Energy module 28 (BLE) and a wireless network module 29 (Wi-Fi). The Bluetooth Low Energy module 28 and the wireless network module 29 are electrically connected to the second controller 26. The second controller 26 transmits the received pressure sensing signals S1 and barometric pressure measurement signals S2 to the outside world through at least one of the Bluetooth Low Energy module 28 and the wireless network module 29. For example, the second controller 26 can communicate with an AI server through the Bluetooth Low Energy module 28 or the wireless network module 29 to transmit the pressure sensing signals S1 and barometric pressure measurement signals S2 to the AI ​​server.

[0054] In one embodiment of the present invention, such as Figure 1 As shown, the first body 10 includes at least one charging port 18, which is exposed on the outer surface of the first housing 11. In this embodiment, please refer to... Figure 7 and Figure 8 The pressure-sensitive smart electronic bracelet 1 can be used with an electronic bracelet charging cabinet 40. The electronic bracelet charging cabinet 40 includes a cabinet body 41, multiple charging posts 42, multiple indicator lights 43, and multiple ultraviolet (UV) lamps 44. The cabinet body 41 has at least one bracelet setting space 410 inside. Each bracelet setting space 410 is provided with a limiting bracket 411, multiple charging posts 42, multiple indicator lights 43, and multiple ultraviolet (UV) lamps 44. The limiting bracket 411 includes multiple limiting notches 412, each of which provides a pressure-sensitive smart electronic bracelet 1 for mounting. The position of the limiting notch 412 corresponds to the position of a charging post 42 and the position of an indicator light 43. Therefore, when the pressure-sensitive smart electronic bracelet 1 is placed in an electronic bracelet charging cabinet 40, the at least one charging port 18 can be electrically connected to a charging post 42 for charging. For example, the at least one charging port 18 magnetically attracts each of the charging posts 42. The indicator light 43 is used to indicate the charging status of the pressure-sensitive smart electronic bracelet 1 to the user. The multiple ultraviolet lamps 44 are used to emit ultraviolet light to illuminate the pressure-sensitive smart electronic bracelet 1 placed in the bracelet placement space 410.

[0055] In another embodiment of the invention, such as Figure 2 As shown, the first body 10 includes a near-field communication tag 19 (NFCTag), which is disposed in the first accommodating space. The NFCTag 19 contains identification information, such as a unique identifier (UID). In this embodiment, please refer to... Figure 9The pressure-sensitive smart electronic bracelet 1 can be used with an identity pairing device 50. The identity pairing device 50 includes a housing 51, a touch screen 52, a card slot 53, and a bracelet positioning slot 54. The touch screen 52, the card slot 53, and the bracelet positioning slot 54 are disposed on the housing 51. The touch screen 52 can be operated by the user. The card slot 53 can be used to insert a person's ID card (e.g., health insurance card). The bracelet positioning slot 54 is used to set a pressure-sensitive smart electronic bracelet 1, and then wears the pressure-sensitive smart electronic bracelet 1 at a specific position on the user's hand according to the user's operation. A near-field communication reader 55 (NFC reader) and a camera lens 56 are respectively provided at the bottom and top of the bracelet positioning slot 54. The near-field communication reader 55 is used to read the near-field communication tag 19 of each pressure-sensitive smart electronic bracelet 1, and the camera lens 56 is used to photograph the internal space of the bracelet positioning slot 54.

[0056] In short, the application of the pressure-sensitive smart electronic bracelet 1 and the identity pairing device 50 is as follows: First, the user inserts their personal identification document into the card slot 53 for identity verification. Then, the pressure-sensitive smart electronic bracelet 1 is placed in the bracelet positioning slot 54. The near-field communication reader 55 reads the identification information from the near-field communication tag 19, and the identity pairing device 50 verifies this identification information and pairs it with the user's identity. Next, the identity pairing device 50 activates the camera lens 56 and displays the information on the touch screen 52. The system displays operation prompts, instructing the user to insert their hand into the positioning slot 54 of the wristband. The user can adjust the position of their hand via the touch screen 52, aligning the specific position of their hand with the pressure-sensitive smart electronic wristband 1 for positioning. Preferably, the pressure-sensitive smart electronic wristband 1 can connect to the identity pairing device 50 via the aforementioned Bluetooth Low Energy module 28 or the wireless network module 29. The user can then operate the functions of the pressure-sensitive smart electronic wristband 1 through the identity pairing device 50, such as activating the air pump 12 to measure the user's physiological values.

[0057] In another embodiment of the present invention, the air pump 12 is connected to the control circuit board 22, and the control circuit board 22 is communicatively connected to a mobile device M with a shooting function (such as a camera) via the Bluetooth Low Energy module 28 or the wireless network module 29. Figure 10 As shown), the mobile device M can be, for example, a smartphone. The mobile device M is used to photograph the internal space of an assistive wearable mold 60. Specifically, a first opening 61 is formed on the top of the assistive wearable mold 60. The user can place the mobile device M on the top of the assistive wearable mold 60 to photograph the internal space of the assistive wearable mold 60 through the first opening 61.

[0058] In short, the user can first run an application (APP) on the mobile device M and log in to the application to verify their identity. Then, the user can place the pressure-sensitive smart electronic bracelet 1 into the auxiliary wearable mold 60. Next, the user can operate the application to perform the shooting function of the mobile device M and display operation prompts on the screen of the mobile device M, prompting the user to put their hand into the auxiliary wearable mold 60 and adjust the position of their hand through the touch screen 52 so that the specific position of the user's hand is aligned with the pressure-sensitive smart electronic bracelet 1. The user can then fasten the bracelet strap 30 to complete the wearing process. Preferably, the user can operate the functions of the pressure-sensitive smart electronic bracelet 1 through the mobile device M, such as controlling the air pump 12 to turn on or off through the mobile device M.

[0059] The pressure-sensitive smart electronic bracelet 1 of this invention can execute a blood pressure measurement process and a pulse measurement process respectively. First, the blood pressure measurement process is described, which includes the following steps:

[0060] 1. When the pressure-sensitive smart electronic bracelet 1 is worn on a user's wrist, the air pump 12 of the pressure-sensitive smart electronic bracelet 1 inflates the airbag 23 according to the user's operation; for example, as in the aforementioned embodiment, the user can activate the air pump 12 through the at least one button 14 or the screen 15 to inflate the airbag 23, or the user can set the air pump 12 to start automatically to inflate the airbag 23 through the at least one button 14 or the screen 15.

[0061] 2. When the air pump 12 stops operating and the airbag 23 deflates, the control circuit board 22 receives the pressure sensing signal S1 transmitted by each pressure sensor 24 and performs multiple signal processing steps on each pressure sensing signal S1 to obtain a pulse amplitude signal. For example, in the embodiment described above, the first controller 17 is connected to the control circuit board 22 and the air pump 12 and has a preset air pressure threshold value. The first controller 17 determines whether the air pressure value inside the airbag 23 is greater than the air pressure threshold value based on the air pressure measurement signal S2. If so, it means that the airbag 23 is full of gas. The first controller 17 controls the air pump 12 to turn off to stop inflating the airbag 23.

[0062] When the air pump 12 stops inflating the airbag 23, the airbag 23 will deflate. During the deflation process, the pressure change curve C1 in the airbag 23 will be as follows: Figure 11 As time gradually decreases, and during this process, the control circuit board 22 performs multiple signal processing steps on each of the pressure sensing signals S1 to obtain the following: Figure 12The pulse amplitude signal C2 shown may include, for example, at least one signal filtering process and at least one signal amplification process.

[0063] 3. For example Figure 13 As shown, the control circuit board 22 (the pressure-sensitive smart electronic bracelet 1) transmits the pulse amplitude signal to an AI server 70. The AI ​​server 70 performs deep analysis and calculations to extract multiple feature point information, including systolic blood pressure information and diastolic blood pressure information. For example, the AI ​​server 70 includes a data transmission module 71, a calculation module 72, and a database 73. The calculation module 72 connects the data transmission module 71 and the database 73. The data transmission module 71 is used to receive information transmitted by the pressure-sensitive smart electronic bracelet 1 or to send information externally. The calculation module 72 has multiple built-in algorithms and can analyze and calculate the signal transmitted by the pressure-sensitive smart electronic bracelet 1. For example, such as... Figure 14 As shown, the calculation module 72 superimposes the air pressure change curve C1 with the pulse amplitude signal C2 to obtain multiple intersection points, which are the multiple feature point information.

[0064] Alternatively, the computing module 72 can perform deep analysis and calculation on the signal transmitted by the pressure-sensitive smart electronic bracelet 1 to obtain multiple analysis results, and then transmit these multiple analysis results to the pressure-sensitive smart electronic bracelet 1 or a medical institution 80 through the data transmission module 71, so that the user or the medical staff in the medical institution 80 can understand the user's physiological state; the database 73 is used to record the information transmitted by the pressure-sensitive smart electronic bracelet 1 or the information calculated by the computing module 72.

[0065] The pulse measurement process is partially the same as the blood pressure measurement process. The difference is that when the air pump 12 stops operating and the airbag 23 deflates, the control circuit board 22 receives the pressure sensing signal S1 transmitted by each pressure sensor 24 and performs multiple signal processing steps on each pressure sensing signal S1 to obtain a pulse wave signal. Then, it performs a Fourier transform on the pulse wave signal to obtain a high-frequency signal and a low-frequency signal. The pulse wave signal, the high-frequency signal, and the low-frequency signal are then transmitted to the AI ​​server 70. The AI ​​server 70 performs deep analysis and calculation to extract multiple feature waveform information.

[0066] The pressure-sensitive smart electronic bracelet 1 of the present invention includes a first body 10 and a second body 20. Compared with the electronic bracelets described in the prior art, it increases the space for physical sensors, thus making the types of physiological data measurement unrestricted. The second body 20 is provided with a plurality of pressure sensors 24, each pressure sensor 24 having a contact portion 240. When a user wears the pressure-sensitive smart electronic bracelet 1, each pressure sensor 24 transmits the user's pulse through the contact portion 240 to generate a pressure sensing signal. Furthermore, the second body 20 is provided with an airbag 23. When the airbag... When the airbag 23 is inflated, each of the contact portions 240 protrudes further from the second body 20, increasing the contact area with the user's skin. Furthermore, due to the pushing action of the airbag 23, the tightness between each of the contact portions 240 and the user's skin is enhanced. Compared to the prior art, which only senses pulse data through optical principles, where the transmitting end (or receiving end) of the optical sensor may be obstructed by external objects, resulting in inaccurate pulse data, the pressure-sensitive smart electronic bracelet 1 of this invention measures the user's pulse data through physical contact conduction, which can effectively improve the accuracy of measuring physiological data such as blood pressure and pulse.

[0067] This pressure-sensitive smart electronic bracelet 1 features unique physical sensing technology, enabling it to instantly detect the user's vital signs, including physiological indicators such as blood pressure and pulse. The bracelet transmits this data to the AI ​​server 70, where it undergoes in-depth analysis and computation to obtain multiple analytical results. These results are fed back to the user and simultaneously provided to relevant medical institutions, allowing healthcare professionals to quickly understand the user's physiological state and provide effective medical treatment and recommendations.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the technical solution of the present invention.
