Title:
SWEAT SENSOR AND SWEAT SENSOR SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/142910
Kind Code:
A1
Abstract:
A sweat sensor and a sweat sensor system. The sensor comprises: a sweat guiding electrode layer (2) comprising an insulating layer (21), a conductive electrode arranged in the insulating layer (21), and a first through hole penetrating the insulating layer (21) and the conductive electrode; an adhesive layer (3) arranged on the insulating layer (21) and provided with a second through hole which is in communication with the first through hole; and a water absorption diffusion layer (4) arranged on the adhesive layer (3) and covering the second through hole. The sweat sensor system has a plurality of sweat sensors. The sweat sensor can continuously and simultaneously measure the sweat amount and the electrolyte concentration in real time, and can avoid the interference caused by the mixing of new sweat and old sweat on electrolyte concentration measurement.
