Title:
WEARABLE PASSIVE SWEAT DETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/213056
Kind Code:
A1
Abstract:
A wearable passive sweat detection device, comprising at least one detection sensor (1). The detection sensor (1) comprises: a substrate (10); a sensing element arranged on the substrate (10), wherein the sensing element comprises a sweat collection portion and a sweat self-driven detection portion, the sweat collection portion is used for collecting sweat secreted from sweat glands of skin, the sweat self-driven detection portion comprises a guide portion (201) of a semi-conical structure, a test electrode (203) arranged on an outer conical surface of the guide portion (201), and a back electrode (204), and a narrow end of the guide portion (201) faces the sweat collection portion; and a test element (30), wherein the test element (30) is connected to the test electrode (203) and the back electrode (204). According to the detection device, by using a conical structure, a liquid-solid friction effect is achieved to achieve passive detection of sweat components; in addition, flexibility is achieved, and convenience of wearing is achieved; and by using different ion-selective membranes, different ion concentrations can be measured.
