Embodiment 1
[0034] Embodiment 1, the preparation of conductive liquid temperature sensor chip and its response to temperature
[0035] 1. The structure of the conductive liquid temperature sensor chip
[0036] Such as figure 1 As shown, the temperature sensing chip of the present invention includes a chip body with a thickness of 2 to 200 microns made of degradable polymer materials such as polyvinyl alcohol, polylactic acid, polyethylene glycol or polycaprolactone; A microchannel with a depth of 1-1000 microns, a width of 1-1000 microns, and a length of 0.01-10 cm; the two ends of the micro-channel communicate with the outside through the openings on the chip body to form an electrode interface; the electrode interface It is connected with matching electrodes; the micro-channel is filled with conductive liquid, and the solvent of the conductive liquid is either water or alcohol; the chemical formula of alcohol is CH 3 (CH 2 ) n OH, HO (CH 2 ) n OH, HO (CH 2 Oh) n OH or HO(CH 2 )...
