Description

Technical Field

[0001] The present invention relates to a pressure-sensitive smart electronic bracelet, and more particularly to a pressure-sensitive smart electronic bracelet capable of detecting vital signs such as a user's blood pressure, pulse, and other physiological indicators by pressure detection, and a method of using the same.

Background Art

[0002] With the development of science and technology, smartphones are widely used, and the convenience of daily activities has been improved by various functions such as mobile payment and daily vital sign recording. However, some daily events are not favorable for the user to carry a smartphone to perform the above functions. For example, due to its size and weight, a smartphone is not favorable for the user to carry it while exercising, which hinders the user from recording vital signs during exercise.

[0003] Therefore, wearable smart devices have been invented to facilitate the user to perform some smartphone functions by wearable smart devices in specific situations. For example, an electronic bracelet (wearable smart device) is lighter and more compact than a smartphone, so the user can wear it for a longer time compared to a smartphone, enabling the electronic bracelet to record daily physiological data more extensively.

[0004] To make it compact, the space for accommodating a physiological data sensor in the electronic bracelet is reduced, and thus the type of the physiological data sensor is limited. For example, most conventional electronic bracelets mainly rely on the optical principle to detect physiological data. An optical sensor is provided on the inner surface of a conventional electronic bracelet. When a user wears the electronic bracelet, the optical sensor adheres to the user's skin and detects the light intensity signal reflected by the user's blood using optical principles. The processing device within the electronic bracelet calculates multiple physiological data, such as pulse rate, blood pressure, and body temperature, according to the light intensity signal. However, electronic bracelets only calculate multiple physiological data based on light intensity signals, and the accuracy of measurements of data such as pulse rate and blood pressure is uncertain. Therefore, conventional electronic bracelets must be improved in terms of the accuracy of the acquired physiological data through physical methods such as pressure-based detection.

[0006] Conventional electronic bracelets primarily rely on photodetection principles to acquire the user's physiological data, making the measurement accuracy of some physiological data uncertain. To overcome the aforementioned problems, the present invention provides a pressure-sensitive smart electronic bracelet and a method for using the same, the pressure-sensitive smart electronic bracelet detecting the user's physiological data by physical sensing technology (pressure sensing) to improve the accuracy of measuring physiological data such as blood pressure and pulse rate. [Means for solving the problem]

[0007] The pressure-sensitive smart electronic bracelet of the present invention The first body, A first shell having a first side and a second side opposite to the first side, wherein the first side is connected to a bracelet band, and the first shell has a first housing space inside, and An air pump located in the first containment space, A first body comprising, The second body, A second shell connected to a second side of the first shell, having a second containment space inside the second shell, A control circuit board, located within a second containment space, having a first surface and a second surface opposite to the first surface, Multiple pressure sensing groups, each pressure sensing group comprising multiple pressure sensors arranged on a first surface of a control circuit board, each pressure sensor being electrically connected to the control circuit board with its contact portion exposed from the outer surface of a second shell, and each pressure sensor detecting user pulse information and generating a pressure sensing signal accordingly, and Located within the second containment space, between the second surface of the control circuit board and the second shell, an airbag connected to an air pump, A second main body equipped with It is equipped with.

[0008] One method of using the aforementioned pressure-sensitive smart electronic bracelet is provided: When this pressure-sensitive smart electronic bracelet is worn on the user's wrist, the air pump in the pressure-sensitive smart electronic bracelet inflates the airbag in response to the user's input. When the air pump stops operating and the airbag is deflating, the control circuit board receives pressure detection signals transmitted by each pressure sensor, performs multiple signal processing processes on each pressure detection signal to obtain a pulse amplitude signal, and sends the pulse amplitude signal to an AI (artificial intelligence) server, which extracts multiple feature point information through deep analysis and computation. Multiple feature point information includes systolic blood pressure information and diastolic blood pressure information.

[0009] Another use of the aforementioned pressure-sensitive smart electronic bracelet is provided. When this pressure-sensitive smart electronic bracelet is worn on the user's wrist, the air pump in the pressure-sensitive smart electronic bracelet inflates the airbag in response to the user's input. When the air pump stops operating and the airbag is deflating, the control circuit board receives pressure detection signals transmitted by each pressure sensor, performs multiple signal processing processes on each pressure detection signal to obtain a pulse wave signal, performs a Fourier transform on this pulse wave signal to obtain high-frequency and low-frequency signals, and transmits the pulse wave signal, high-frequency signal, and low-frequency signal to an AI server, which extracts multiple feature wave information through deep analysis and computation.

[0010] The pressure-sensitive smart electronic bracelet of the present invention comprises a first body and a second body. In contrast to the prior art, this invention increases the space for accommodating physiological data sensors while maintaining compatibility with various sensor types. The second main body is equipped with multiple pressure sensors, each having a contact portion. When a user wears the pressure-sensitive smart electronic bracelet, each pressure sensor receives the user's pulse information via the contact area and generates a pressure detection signal accordingly. Furthermore, the airbags are located within the second main unit. When the airbag inflates, each contact point can protrude further from the outer surface of the second body, increasing the contact area with the user. Each contact part is pushed by the airbag and adheres more closely to the user. Conventional electronic bracelets only detect the pulse data by using the light sensor of its light-emitting terminal device (or light-receiving terminal device), which is easily obstructed by objects such as dust and moisture. As a result, the pulse data detected by the light sensor becomes inaccurate. The pressure-sensitive smart electronic bracelet of the present invention measures the user's pulse data through physical contact and effectively improves the measurement accuracy of physiological data such as blood pressure and pulse state.

[0011] The pressure-sensitive smart electronic bracelet of the present invention features a unique physical detection technology and can immediately detect the user's vital signs including blood pressure, pulse state and other physiological indicators. The pressure-sensitive smart electronic bracelet transmits the acquired data to the AI server, and the AI server performs deep analysis and calculation to obtain multiple analysis results. The multiple analysis results can be fed back to the user and can also be provided to relevant medical institutions at the same time. As a result, healthcare providers can quickly gain insights into the user's physiological state, facilitating appropriate medical intervention and advice.

[0013] A detailed description, accompanied by embodiments shown in the drawings, of the technical features and practical effects of the present invention, along with the embodiments for achieving them in accordance with the content of the invention, is as follows.

[0014] Referring to Figures 1 to 3, the pressure-sensitive smart electronic bracelet 1 of the present invention comprises a first body 10, a second body 20, and a bracelet band 30. The first main body 10 is connected to the second main body 20 and the bracelet band 30, respectively. In particular, the second main body 20 and the bracelet band 30 are connected to two opposing sides of the first main body 10, respectively. The bracelet band 30 is detachably connected to the second main body 20. When the bracelet band 30 is connected to the second main body 20, the pressure-sensitive smart electronic bracelet 1 takes on an annular shape as shown in Figure 3 for the user to wear.

[0015] The first main body 10 comprises a first shell 11 and an air pump 12. The first shell 11 has a first side and a second side opposite to this first side. Furthermore, the first side is connected to the bracelet band 30, and the second side is connected to the second main body 20. The first shell 11 has a first containment space (not shown) inside. The air pump 12 is located within the first containment space. In particular, the first shell 11 has a flow path 13 formed in it that connects the first containment space with the outside of the first shell 11. When the air pump 12 is activated, air from outside the first shell 11 can be drawn in through the flow path 13 for expansion.

[0016] Furthermore, in one embodiment of the present invention, the first main body 10 includes at least one button 14, a screen 15, an optical sensor 16, and a first control device. The first control device is electrically connected to at least one button 14, a screen 15, an optical sensor 16, and an air pump 12.

[0017] At least one button 14 is located on at least one outer surface of the first shell 11 and is operable by the user to perform functions of the pressure-sensitive smart electronic bracelet 1, such as turning on the air pump 12 by pressing at least one button 14. The screen 15 is located within the first containment space with its display surface exposed from the outer surface of the first shell 11. Preferably, screen 15 is a touchscreen. Referring to Figure 3, when the pressure-sensitive smart electronic bracelet 1 is worn on the user's wrist W, the surface of the first shell 11 that comes into contact with the user is defined as the user contact surface 110. The screen 15 is exposed from the outer surface opposite to the user contact surface 110, and as a result can be operated by the user to perform the functions of the pressure-sensitive smart electronic bracelet 1. For example, in addition to turning on the air pump 12 by at least one button 14 as described above, the user can also turn on the air pump 12 by touching the screen 15.

[0018] The optical sensor 16 is located within the first housing space with its detection surface exposed from the outer surface of the first shell 11. In particular, the detection surface of the optical sensor 16 is exposed from the user contact surface 110, and the optical sensor 16 emits light from its detection surface and receives reflected light in order to detect the user's physiological data. The first control device is located within the first containment space and is, for example, a microcontroller (MCU).

[0019] The second main body 20 comprises a second shell 21, a control circuit board 22, an airbag 23, and a plurality of pressure sensing groups. The second shell 21 is connected to the second side of the first shell and, preferably, is rotatably connected to the first shell 11. Referring to Figures 4 and 5, the second shell 21 has a second housing space 210 inside, and the control circuit board 22 is located within the second housing space 210. The control circuit board 22 has a first surface 220 and a second surface 221 opposite to the first surface 220, and the airbag 23 is located within the second containment space 210. The airbag 23 is located between the second surface 221 of the control circuit board 22 and the second shell 21, and is connected to the air pump 12, and the volume of the airbag 23 can be adjusted depending on the on / off state of the air pump 12.

[0020] For example, referring to Figures 1 and 2, the airbag 23 is connected to the air pump 12 by a pipe 230. When the air pump 12 is turned on, the air drawn into the air pump 12 from the flow path 13 passes through the pipe 230 and fills the airbag 23, thereby inflating the airbag 23. If the air pump 12 is turned off for a certain period of time, the air inside the airbag leaks out of the passage 13 through the air pump 12 or the pipe 230, thereby returning the airbag to a deflated state.

[0021] Each pressure detection group comprises a plurality of pressure sensors 24 arranged on the first surface 220 of the control circuit board 22. Specifically, referring to Figures 3 to 5, the outer surface of the second shell 21 includes an inner surface 211 and an outer surface 212, and each pressure sensor 24 includes a contact portion 240 and a sensor body 241, with each contact portion 240 being exposed from the inner surface 211 and connected to each sensor body 241. The outer surface 212 is provided with a bracelet fixing portion 25 that is detachably connected to the bracelet band 30. For example, the bracelet fixing part 25 is a bracelet buckle, and the bracelet band 30 can pass through the bracelet buckle and be fastened with the buckle in order to connect to the second body 20.

[0022] When the pressure-sensitive smart electronic bracelet 1 is attached to the user's wrist W, each contact portion 240 comes into contact with the wrist W, and the volume change of the airbag 23 can increase or decrease the contact area between each contact portion 240 and the user (wrist W). When the airbag 23 inflates, it pushes and moves the control circuit board 22, causing the contact portion 240 to be further pushed out of the second containment space 210 (as shown in Figure 5). The area of ​​the contact portion 240 exposed from the inner surface 211 increases, and the contact area between each contact portion 240 and the user also increases. Furthermore, each contact portion 240 can be pressed against the user's wrist W by the airbag 23, allowing for a tighter fit.

[0023] Referring to Figure 6, each pressure sensor 24 is electrically connected to the control circuit board 22 and is adapted to detect the user's pulse information (known as heartbeat) and generate a pressure detection signal S1. In particular, the control circuit board 22 includes a second control device 26, and the second control device may be a microcontroller. The second control device 26 is electrically connected to each pressure sensor 24. Preferably, the second control device 24 is electrically connected to the sensor body 241 of each pressure sensor 24. The user's pulsation information can be transmitted to each sensor body 241 via each contact portion 240, and each sensor body 241 transmits an analog signal, which is a pressure detection signal S1, to the second control device 24. It should be noted that when each contact portion 240 is pressed by the airbag 23 and becomes more closely attached to the wrist W, the signal strength of the pressure detection signal S1 generated by each pressure sensor is increased (compared to the uninflated state of the airbag 23).

[0024] In one embodiment of the present invention, the plurality of pressure sensors 24 include a plurality of first pressure sensors and a plurality of second pressure sensors. Each first pressure sensor transmits a first pressure detection signal to the control circuit board 22, and each second pressure sensor transmits a second pressure detection signal to the control circuit board 22. In other words, each pressure detection group transmits a first pressure detection signal and a second pressure detection signal to the control circuit board 22 (second control device 26), and the control circuit board (second control device 26) calculates the difference between each first pressure detection signal and each second pressure detection signal to generate a plurality of pressure processing signals.

[0025] In particular, each pressure sensing group includes a first pressure sensor and a second pressure sensor, and the contact portion 240 of each first pressure sensor and the contact portion 240 of each second pressure sensor are located on two opposite sides of the inner surface 211 of the second shell 21, respectively. When a user is wearing the pressure-sensitive smart electronic bracelet 1, at least one of the multiple detection groups can correspond to the location of the user's artery, and the contact portion 240 of the first pressure sensor of at least one detection group and the contact portion 240 of the second pressure sensor of at least one detection group can also correspond to the location of the user's artery.

[0026] The second control device 26 is configured to compare the waveform amplitudes of the first pressure detection signal and the second pressure detection signal of the pressure detection group and designate the signal with the smaller amplitude as the reference signal.

[0027] The second control device 26 generates a pressure processing signal by subtracting a reference signal from the other of the two pressure detection signals, typically the one with the larger amplitude, between the first pressure detection signal and the second pressure detection signal. For example, if the first pressure detection signal of a given pressure detection group has a smaller waveform amplitude, the second control device 26 designates it as the reference signal. Next, the first pressure detection signal is subtracted from the second pressure detection signal to generate the corresponding pressure processing signal.

[0028] The second control device 26 applies the same subtraction process to other pressure sensing groups that are not aligned with the user's artery. However, in these cases, the resulting pressure processing signal has a value of 0. In contrast, in the pressure sensing group corresponding to the user's arteries, the pressure processing signal generates non-zero values, which suggests the presence of arterial pressure fluctuations.

[0029] In one embodiment of the present invention, referring to Figure 6, the second control device 26 is connected to the first control device 17 and the pneumatic sensor 27. The air pressure sensor 27 is located within the second containment space 210 and is configured to detect the air pressure inside the airbag 23 and generate an air pressure measurement signal S2 for the second control device 26. The second control device 26 transmits the air pressure measurement signal S2 to the first control device 17, which in turn controls the air pump 12 to turn off in response to the air pressure measurement signal S2. For example, the first control device 17 sets an air pressure threshold in advance and determines whether the air pressure value of the airbag 23 is greater than the air pressure threshold in response to the air pressure measurement signal S2. If the value is large, it means that the airbag 23 is filled with air, and the first control device 17 controls the air pump 12 to turn off in order to stop the inflation of the airbag 23.

[0030] In this embodiment, the control circuit board 22 is Bluetooth (Registered trademark) It further comprises at least one of a low-energy module 28 (BLE) and a wireless network module 29 (such as a Wi-Fi module). The Bluetooth low energy module 28 and the wireless network module 29 are each electrically connected to the second control unit 26. The second control device 26 outputs the received pressure detection signal S1 and air pressure measurement signal S2 via at least one of the Bluetooth low energy module 28 and the wireless network module 29. For example, the second control device 26 can communicate with an AI (artificial intelligence) server via a Bluetooth low-energy module 28 or a wireless network module 29 to transmit a pressure detection signal S1 and an air pressure measurement signal S2 to the AI ​​server.

[0031] In one embodiment of the present invention, the first body 10 includes at least one charging port 18 exposed from the outer surface of the first shell 11, as shown in Figure 2. In this embodiment, as shown in Figures 7 and 8, the pressure-sensitive smart electronic bracelet 1 can cooperate with an electronic bracelet charging cabinet 40 which includes a cabinet housing 41, a plurality of charging columns 42, a plurality of indicator lights 43, and a plurality of ultraviolet (UV) lights 44. The cabinet housing 41 includes at least one bracelet storage space 410 inside, each bracelet storage space 410 comprising a frame 411, a plurality of charging columns 42, a plurality of indicator lights 43, and a plurality of ultraviolet lights 44. The frame 411 is further equipped with multiple slots 412, each of which is fitted for inserting and installing the pressure-sensitive smart electronic bracelet 1. The position of each slot 412 corresponds to the position of the charging column 42 and the indicator light 43. Therefore, when the pressure-sensitive smart electronic bracelet 1 is placed inside the electronic bracelet charging cabinet 40, at least one charging port 18 can be electrically connected to the charging column 42 for charging. For example, at least one charging port 18 is magnetically attracted to each charging column 42, and indicator lights 43 are adapted to let the user know the charging status of the pressure-sensitive smart electronic bracelet 1. Multiple ultraviolet lamps 44 are positioned to irradiate ultraviolet light onto the pressure-sensitive smart electronic bracelet 1 located within the bracelet housing space 410, thereby performing disinfection.

[0032] In another embodiment of the present invention, the first body 10 includes a near-field communication tag 19 (NFC tag), as shown in Figure 2. The short-range wireless communication tag 19 is then placed in the first storage space along with the identification information stored in the short-range wireless communication tag 19, in which case the identification information may be, for example, a unique identifier (UID). In the present invention, referring to Figure 9, the pressure-sensitive smart electronic bracelet 1 can cooperate with an identity pairing device 50 which comprises a shell 51, a touchscreen 52, a card slot 53, and a bracelet alignment recess 54. The touchscreen 52, card slot 53, and bracelet alignment recess 54 are located on the shell 51. The touchscreen 52 is adapted for user touch operation, and the card slot 53 is adapted for user insertion of personal identification documents (such as a health insurance card). The pressure-sensitive smart electronic bracelet 1 is housed in the bracelet alignment recess 54 and then attached to a specific position on the user's wrist in response to user operation. Furthermore, a near-field wireless communication reader 55 (NFC reader) and a lens 56 are provided at the bottom and top of the bracelet alignment recess 54, respectively. The near-field wireless communication reader 55 is adapted to read the near-field wireless communication tag 19 of the pressure-sensitive smart electronic bracelet 1 using a lens 56 adapted to capture the internal space of the bracelet alignment recess 54.

[0033] The following describes how the pressure-sensitive smart electronic bracelet 1 and the identity pairing device 50 work together. In short, first, the user inserts their personal identification document into the card slot 53 to verify their identity, and then places the pressure-sensitive smart electronic bracelet 1 into the bracelet alignment recess 54. The near-field wireless communication reader 55 reads the identity verification information in the near-field wireless communication tag 19, and the identity pairing device 50 verifies the identity verification information and links it to the user's identity. Next, the identity pairing device 50 activates the lens 56 and displays operation instruction information on the touchscreen, prompting the user to place their hand into the bracelet alignment recess 54. The user can adjust their hand via the touchscreen 52 to complete the alignment process with the pressure-sensitive smart electronic bracelet 1. Preferably, the pressure-sensitive smart electronic bracelet 1 can connect to the identity pairing device 50 via the aforementioned Bluetooth low-energy module 28 or wireless network module 29. The user can operate the functions of the pressure-sensitive smart electronic bracelet 1 on the identity pairing device 50, such as turning on the air pump 12 to measure the user's physiological data.

[0034] In another embodiment of the present invention, the air pump 12 is connected to the control circuit board 22. The control circuit board 22 is connected to a mobile device M having a shooting function via a Bluetooth low-energy module 28 or a wireless network module 29 (as shown in Figure 10), and the mobile device M may be a smartphone. The mobile device M is then adapted to capture images of the internal space of the auxiliary mounting frame 60. In particular, the first opening 61 is located on the top of the auxiliary mounting frame 60, and the user can position a mobile device M to photograph the internal space of the auxiliary mounting frame 60 through the first opening 61.

[0035] The following describes how the mobile device M, the pressure-sensitive smart electronic bracelet 1, and the auxiliary mounting frame 60 work together. In short, first, the user runs the application (APP) on their mobile device M, logs into the application, and verifies their identity. The user then places the pressure-sensitive smart electronic bracelet 1 inside the auxiliary mounting frame 60 and operates the application to perform the shooting function of the mobile device M. The screen of the mobile device M displays instructions prompting the user to place their hand inside the auxiliary mounting frame 60. The user can adjust the specific position on their hand through the screen of the mobile device M to fit the pressure-sensitive smart electronic bracelet 1. Afterward, the user can fasten the bracelet band 30 with the buckle themselves to complete the wearing process. Preferably, the user can operate the functions of the pressure-sensitive smart electronic bracelet 1 on the mobile device M, such as turning the air pump 12 on or off using the mobile device M.

[0036] The pressure-sensitive smart electronic bracelet 1 of the present invention can perform a blood pressure measurement process and a pulse rate state measurement process, respectively. First, let me explain the blood pressure measurement process. The following steps are included.

[0037] When the pressure-sensitive smart electronic bracelet 1 is worn on the user's wrist, the air pump 12 of the pressure-sensitive smart electronic bracelet 1 inflates the airbag 23 in response to the user's operation. For example, as in the embodiment described above, the user can either turn on the air pump 12 via at least one button 14 or screen 15 to inflate the airbag, or have the air pump 12 automatically turn on via at least one button 14 or screen 15 to inflate the airbag 23.

[0038] 2. When the air pump 12 stops operating and the airbag 23 deflates, the control circuit board 22 receives the pressure detection signal S1 transmitted by each pressure sensor 24 and performs a plurality of signal processing processes on each of these pressure detection signals S1 to obtain the pulse amplitude signal C2. For example, similar to the embodiment described above, the first control device 17 is connected to the control circuit board 22 and the air pump 12, presets an air pressure threshold, and determines whether the air pressure value inside the airbag 23 is greater than the air pressure threshold in response to the air pressure measurement signal S2. If the value is large, it means that the airbag 23 is filled with air, and the first control device 17 controls the air pump 12 to turn off in order to stop the inflation of the airbag 23.

[0039] Then, when the air pump 12 stops inflating the airbag 23, the airbag 23 deflates. During the deflation of the airbag 23, the air pressure inside the airbag 23 gradually decreases over time, as shown by the air pressure change curve C1 in Figure 11. The control circuit board 22 performs a plurality of signal processing processes on each pressure detection signal S1 in order to obtain a pulse amplitude signal C2 as shown in Figure 12 during the contraction of the airbag 23, and the plurality of signal processing processes include at least one signal filtering process and at least one signal amplification process.

[0040] 3. Referring to Figure 13, the control circuit board 22 (pressure-sensitive smart electronic bracelet 1) transmits the pulse amplitude signal C2 to the AI ​​server 70, and the AI ​​server extracts multiple feature point information through deep analysis and calculation. Multiple feature point information includes systolic blood pressure information and diastolic blood pressure information. For example, the AI ​​server 70 comprises a data transmission module 71, a computing module 72, and a database 73, with the computing module 72 connected to the data transmission module 71 and the database 73. The data transmission module 71 is adapted to receive or output information transmitted by the pressure-sensitive smart electronic bracelet 1. The computing module 72 incorporates multiple algorithms for analyzing and calculating information transmitted by the pressure-sensitive smart electronic bracelet 1. For example, referring to Figure 14, the computing module 72 superimposes the air pressure change curve C1 and the pulse amplitude signal C2 to obtain multiple intersection points. Multiple intersections represent multiple feature point information.

[0041] Furthermore, the computing module 72 performs deep analysis and calculations on the signals transmitted by the pressure-sensitive smart electronic bracelet 1 to obtain multiple analysis results. The data transmission module then sends multiple analysis results to the pressure-sensitive smart electronic bracelet 1 or the medical institution 80, allowing the user or medical professional to quickly understand the user's physiological state. The database 73 is adapted to record information transmitted by the pressure-sensitive smart electronic bracelet 1 or calculated by the computing module 72.

[0042] Each step in the pulse rate measurement process is partially the same as each step in the blood pressure measurement process, with the differences being as follows: When the air pump 12 stops operating and the airbag 23 is contracting, the control circuit board 22 receives the pressure detection signal S1 transmitted by each pressure sensor 24 and performs multiple signal processing processes on each of these pressure detection signals S1 to obtain a pulse wave signal. The control circuit board performs a Fourier transform on the pulse wave signal to obtain high-frequency and low-frequency signals, and transmits the pulse wave signal, high-frequency signal, and low-frequency signal to the AI ​​server 70. The AI ​​server then extracts multiple feature wave information through deep analysis and computation.

[0043] The pressure-sensitive smart electronic bracelet 1 of the present invention comprises a first body 10 and a second body 20. In contrast to the prior art, the present invention increases the space available for accommodating physiological data sensors and eliminates limitations on the type of physiological data sensor. The second main body 20 is equipped with a plurality of pressure sensors 24, each of which pressure sensors 24 is equipped with a contact portion 240. When a user wears the pressure-sensitive smart electronic bracelet 1, each pressure sensor 24 receives the user's pulse information via the contact portion 240 and generates a pressure detection signal accordingly. In addition, the airbag 23 is positioned inside the second main body 20, and when the airbag is inflated, each contact portion 240 can protrude further from the outer surface of the second main body 20, increasing the contact area with the user, and the airbag 23 pushes each contact portion 240 to make it fit more snugly against the user. Conventional electronic bracelets only detect pulse data using an optical sensor with a light-emitting terminal (or light-receiving terminal) that is easily interfered with by objects such as dust and moisture, resulting in inaccurate pulse data detected by the optical sensor. In contrast to conventional technology, the pressure-sensitive smart electronic bracelet 1 of the present invention measures the user's pulse data through physical contact and effectively improves the measurement accuracy of physiological data collected by physical means such as blood pressure and pulse status.

[0044] The pressure-sensitive smart electronic bracelet 1 of the present invention features a unique physical sensing technology that can instantly detect the user's vital signs, including blood pressure, pulse rate, and other physiological indicators. The pressure-sensitive smart electronic bracelet 1 transmits the acquired data to the AI ​​server 70, which performs in-depth analysis and calculations to obtain multiple analysis results, which are then fed back to the user and simultaneously provided to the relevant medical institution 80. Therefore, healthcare professionals can quickly understand the user's physiological state, facilitating effective medical treatment and advice.

[0045] Although the present invention has been described above in preferred embodiments, it is not intended to be limited thereto. Those skilled in the art can make changes and modifications to the present invention, provided they do not deviate from the spirit and scope of the invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
