Embodiment 1

[0061] Example 1: A Detachable Portable Sensor for Cell Detection .

[0062] The structural design of the sensor of the first embodiment is shown in Table 1.

[0063] Table 1 Structural design of the sensor

[0064]

[0065] It should be noted that the coordination design of the above components is as follows:

[0066] 1) The positional relationship between the upper PCB board 2 and the upper cover 3: the upper PCB board 2 is above the upper cover 3.

[0067] 2) The positional relationship between the perforation and the accommodating cavity: the perforation provided on the upper PCB board corresponds to the accommodating cavity provided on the upper cover.

[0068] 3) The positional relationship of the lower PCB board 5, the sealing gasket 4 and the base 6: the middle position of the base 6 is provided with the first installation space 15 of the sealing gasket 4 and the second installation space 16 of the lower PCB board 5 ; the first installation space 15 communicate...

Embodiment 2

[0076] Example 2: Design of the sealing gasket .

[0077] Although the sealing gasket is disclosed in the first embodiment, its function and selection strategy are not described. The purpose of the second embodiment is to solve the above problem.

[0078] Structural Design:

[0079] 4 holes are arranged on the sealing gasket, and 4 immersion gold electrodes 13 with fixed area are arranged on the lower PCB board 5;

[0080] The positions of the four holes of the sealing gasket, the four fixed-area immersion gold electrodes 13 provided on the lower PCB board 5, and the accommodating cavity provided by the upper cover 3 correspond to the positions; a small hole ( The hole-immersion gold electrode can be increased or decreased according to the needs, and the number and position of the immersion gold electrode 13 must correspond to the number and position of the cavity).

[0081] principle:

[0082] 1) Four immersion gold electrodes 13 are arranged on the body of the lower PC...
