as shown in fig. 3-4, if the sweat detection device 100 is provided with a sweat detection main board 1, the composite adhesive plaster 200 has a sensor 2 cooperating with the sweat detection main board 1;

the composite tape 200 may be replaceable, and is used as a consumable.

In this embodiment, the bottom of the sweat detection main board 1 is provided with a plurality of bumps 11, and the sweat detection main board 1 is electrically connected with the sensor 2 through the plurality of bumps 11;

the upper part of the sensor 2 is provided with four contacts 21 which are matched with the bumps 11, wherein two contacts 21 are used for transmitting working current, and the other two contacts 21 are used for feeding back detection signals.

Also can adopt shell fragment or spring pin to replace the bump to realize sweat and detect mainboard 1 and sensor 2's electricity and be connected, but this scheme makes sweat detect more and pastes whole thickness thinner.

In this embodiment, the composite adhesive tape 200 includes an upper first adhesive layer 3 and a lower second adhesive layer 4;

The body of the sensor 2 is arranged on the upper part of the first glue layer 3, and the front end of the sensor electrode 22 is positioned in the detection hole 31 and is contacted with sweat;

in this embodiment, the hydrophilic layer 5 is a single-sided hydrophilic film, and one side of the hydrophilic layer, which is close to the sensor 2, has a hydrophilic function;

the first glue film 3 and the second glue film 4 do not have a hydrophilic function.

In the embodiment shown in fig. 6, the composite tape 200 further includes a first protective film 61 and a second protective film 62;

the first protective film 61 and the second protective film 62 are torn off before the sweat detection patch is used;

the first protective film 61 is disposed on the top surface of the first glue layer 3, the second protective film 62 is disposed on the bottom surface of the second glue layer 4, and the first protective film 61 and the second protective film 62 function to maintain the surface tackiness of the unopened composite tape 200 and prevent contamination.
