[0002] Diabetes mellitus is a chronic disease characterized by hyperglycemia, caused by an absolute or relative deficiency and impaired utilization of insulin. It can severely impact human health. Diabetic patients should monitor their blood sugar regularly and maintain stable blood sugar levels through medication or insulin injections. Besides diabetics, athletes and other groups also need to monitor their blood sugar to understand its fluctuations and adjust their nutritional intake accordingly.

[0003] Clinically, blood glucose testing mostly relies on blood sampling. However, this involves piercing the fingertip, causing pain and increasing the risk of infection.

[0039] Example

[0040] See Figure 1-3 In this embodiment, a glucose biosensor is proposed, including a sensing module 100, a circuit board 200, and a charging cable 300.

[0041] The sensing module 100 is disposed on the substrate 110, wherein the substrate 110 is connected to the circuit board 200.

[0042] The sensing module 100 is used to detect the glucose content in sweat secreted by the skin and generate a sensing signal. The sensing module 100 includes a counter electrode 101, a working electrode 102, and a reference electrode 103. The working electrode 102 is in contact with the sweat and catalyzes the glucose oxidation reaction to generate a current signal (i.e., a sensing signal) corresponding to the glucose concentration. The counter electrode 101 provides current reflux to balance electron transfer on the working electrode 102 and ensure the reaction proceeds smoothly. The reference electrode 103 provides a stable potential reference to ensure the accuracy of the potential of the working electrode 102, thereby reducing measurement errors. The specific composition, structure, and working principle of the sensing module 100 can be found in existing technologies and will not be elaborated further here.

[0043] The circuit board 200 is equipped with a microprocessor 210, a rechargeable battery 220, and a charging connection structure 230. The microprocessor 210 is used to process the sensing signals and generate detection data. The counter electrode 101, the working electrode 102, and the reference electrode 103 are all electrically connected to the microprocessor 210.

[0044] like Figures 4-5 As shown, the charging connection structure 230 includes a first component 231 and a second component 232. The first component 231 is fixedly disposed on the circuit board 200 and electrically connected to the rechargeable battery 220. The second component 232 is rotatably electrically connected to the first component 231.

[0045] The charging cable 300 has a connector 310 at one end and a base 320 at the other end. The connector 310 is detachably electrically connected to the second component 232.

[0046] The sensing module 100 can be placed on the wrist, arm, chest, or waist. Since the sensing module 100 is fixedly connected to the circuit board 200, and the first component 231 is also fixedly connected to the circuit board 200, the sensing module 100, circuit board 200, and first component 231 maintain a relatively fixed position relative to the corresponding body part. When charging the rechargeable battery 220, the connecting part 310 needs to be connected to the second component 232. Since the second component 232 is rotatable relative to the first component 231, the user can rotate the second component 232 to connect the connecting part 310 to the second component 232, thereby preventing the charging cable 300 from twisting.

[0047] The base 320 is equipped with a solar charging panel 321 and a wireless charging coil 322: the solar charging panel 321 is aligned with sunlight to convert solar energy into electrical energy, thereby charging the rechargeable battery 220; or, the base 320 is attached to a terminal device such as a mobile phone or tablet, and the position between the base 320 and the terminal device is adjusted so that the wireless charging coil 322 in the base 320 is aligned with the charging coil in the terminal device. The rechargeable battery 220 can be charged through the wireless reverse charging function of the terminal device.

[0048] A solar charging panel 321 is disposed on the surface of the base 320, and a wireless charging coil 322 is disposed inside the base 320. Figure 3 In the diagram, the wireless charging coil 322 is represented by a dashed line.

[0049] This glucose biosensor has multiple charging methods. When the user (i.e. the wearer of the glucose biosensor) is away from home, they can charge the glucose biosensor through solar charging or the reverse charging function of a mobile phone or other device, thus ensuring the glucose biosensor's battery life.

[0050] like Figure 4 As shown, the first component 231 includes a positive electrode 251 and a negative electrode 252, both of which are annular.

[0051] like Figure 5 As shown, the second component 232 includes a first conductive ring 261 and a second conductive ring 262.

[0052] The first conductive ring 261 is in electrical contact with the positive electrode 251 and the two are rotatably connected. The first conductive ring 261 is sleeved on the outside of the positive electrode 251, and its inner wall is in electrical contact with the outer wall of the positive electrode 251. The second conductive ring 262 is in electrical contact with the negative electrode 252 and the two are rotatably connected. The second conductive ring 262 is sleeved on the outside of the negative electrode 252, and its inner wall is in electrical contact with the outer wall of the negative electrode 252. The positive electrode 251 and the second conductive ring 262 are spaced apart.

[0053] In this embodiment, the positive electrode 251, the negative electrode 252, the first conductive ring 261, and the second conductive ring 262 are all coaxially arranged. When the second component 232 rotates relative to the first component 231, the first conductive ring 261 always maintains electrical contact with the positive electrode 251, and the second conductive ring 262 always maintains electrical contact with the negative electrode 252.

[0054] The positive electrode 251 has a first annular protrusion 2511, which is arranged circumferentially along the positive electrode 251 and coaxially with it. The first conductive ring 261 has a first annular recess 2611, which is also arranged circumferentially along the first conductive ring 261 and coaxially with it. The first annular protrusion 2511 is fitted into the first annular recess 2611, thereby keeping the positive electrode 251 and the first conductive ring 261 relatively fixed axially and preventing them from detaching.

[0055] The negative electrode 252 is provided with a second annular protrusion 2521, which is arranged circumferentially along the negative electrode 252 and coaxially with the negative electrode 252. The second conductive ring 262 is provided with a second annular recess 2621, which is arranged circumferentially along the second conductive ring 262 and coaxially with the second conductive ring 262. The second annular protrusion 2521 is embedded in the second annular recess 2621, thereby keeping the negative electrode 252 and the second conductive ring 262 relatively fixed in the axial direction, ensuring that the negative electrode 252 and the second conductive ring 262 will not detach.

[0056] The first conductive ring 261 is provided with a first terminal 2612, and the second conductive ring 262 is provided with a second terminal 2622.

[0057] The connecting portion 310 is provided with a first conductive contact 311 and a second conductive contact 312. The first conductive contact 311 is used for electrical contact with the first terminal 2612, and the second conductive contact 312 is used for electrical contact with the second terminal 2622. When connecting the connecting portion 310 to the second component portion 232, the first terminal 2612 and the second terminal 2622 can be rotated to align with the first conductive contact 311 and the second conductive contact 312, respectively. Because the second component portion 232 is rotatable, it is easier to manage the charging cable 300 during charging, preventing the charging cable 300 from becoming tangled, twisted, or knotted.

[0058] Specifically, both the first conductive contact 311 and the second conductive contact 312 can be provided with grooves. When connecting the connecting part 310 and the second component part 232, the first terminal 2612 is inserted into the groove of the first conductive contact 311, and the second terminal 2622 is inserted into the groove of the second conductive contact 312.

[0059] like Figure 5 and Figure 6 As shown, in this embodiment, the second component 232 includes an insulating cover 270, a first conductive ring 261 and a second conductive ring 262 disposed inside the insulating cover 270, and a first terminal 2612 and a second terminal 2622 disposed outside the insulating cover 270. The circuit board 200 may be disposed inside a protective shell, wherein the insulating cover 270 partially extends outside the protective shell. It should be noted that the protective shell is not shown in the drawings.

[0060] A magnetic conductor is provided on the insulating cover 270, and a magnet is provided on the connecting part 310, wherein the magnet is magnetically connected to the magnetic conductor. The interaction between the magnet and the magnetic conductor facilitates the connection and disassembly of the second component 232 and the connecting part 310.

[0061] In this embodiment, the base 320 has a built-in energy storage module for storing electrical energy. During charging, excess electrical energy can be stored in the energy storage module for use in emergency situations. The energy storage module includes energy storage batteries such as lithium batteries.

[0062] The seat 320 can be equipped with straps, which can be used to attach the seat 320 to the wrist, backpack, or other locations.

[0063] In this embodiment, a short-range communication module 240 is provided on the circuit board 200, and the short-range communication module 240 is electrically connected to the microprocessor 210. The short-range communication module 240 is used to wirelessly transmit detection data to a terminal. The detection data can be transmitted to terminal devices such as mobile phones via the short-range communication module 240 for convenient viewing by the user.

[0064] The near-field communication module 240 includes a Bluetooth module and / or an NFC module.
