Abstract
A wearable passive sweat detection device includes at least one detection sensor that includes: a base plate; a sensing element provided on the base plate, the sensing element including a sweat collection portion and a sweat self-driven detection portion, the sweat collection portion being configured to collect sweat discharged by sweat glands of skin, the sweat self-driven detection portion including a guide portion of a semi-conical structure, a test electrode provided on an outer conical surface of the guide portion, and a back electrode, and a narrow end of the guide portion facing the sweat collection portion; and a test element connected with the test electrode and back electrode. The adoption of the conical structure achieves a liquid-solid friction effect to realize passive detection of sweat components; meanwhile, flexibility is realized to facilitate wearing; by using different ion selective films, different ion concentrations can be detected; detection precision is high.
