Embodiment 1
[0051] This embodiment provides a sensor with a three-electrode structure for testing blood sugar levels, and the sensor has a flat structure. Including the sensor body 100, the sensor body 100 includes two physical surfaces, each of which is provided with a functional electrode, the physical surface of the sensor body 100 also includes a non-sensing area, one of which is also provided with a non-sensing area There is another functional electrode. Each of the functional electrodes is provided with a corresponding signal conduction area, and each of the functional electrodes is connected to the corresponding signal conduction area. see figure 1 , figure 1 (a) is the top view of the sensor of the present embodiment, figure 1 (b) is the bottom view of the sensor of the present embodiment, figure 1 (c) is a side view of the sensor of this embodiment.
[0052] Specifically, both physical surfaces of the sensor body 100 are provided with base electrodes (ie metal conductors), a...
Embodiment 2
[0064] This embodiment provides a sensor with a three-electrode structure, see Figure 4 , Figure 4 (a) is the top view of the sensor of the present embodiment, Figure 4 (b) is the bottom view of the sensor of the present embodiment, Figure 4 (c) is a side view of the sensor of this embodiment. The sensor of this embodiment includes a flat sensor body 100, the sensor body 100 includes two physical surfaces, one of the physical surfaces is provided with two base electrodes along the axial direction of the sensor, including the first base electrode located at the head end of the sensor body 100 1a and the second base electrode 2a arranged along the axial direction of the sensor, another physical surface of the sensor body 100 is provided with a third base electrode 3a, the first base electrode 1a, the second base electrode 2a and the third base electrode 3a on the head The ends are coated with corresponding chemical coatings to form working electrode 1, reference electrode...
Embodiment 3
[0068] This embodiment provides a biosensor with a four-electrode structure for testing blood sugar, see Figure 5 , Figure 5 (a) is the top view of the sensor of the present embodiment, Figure 5 (b) is the bottom view of the sensor of the present embodiment, Figure 5 (c) is a side view of the sensor of this embodiment. The structure of the biosensor is similar to the structure of Example 1, the difference is that the non-sensing area of the other physical surface of the sensor body 100 is also provided with a second insulating substrate 102, the first insulating substrate 101 , The second insulating substrate 102 is separately provided on the two physical surfaces of the sensor body 100 , so that the head end of the sensor forms a stepped structure.
[0069] In this embodiment, the base electrode 2b is provided on the second insulating substrate 102, coated with a corresponding chemical coating, and an interference electrode 4 is formed to remove the influence of some...
