▎ 摘　　要

NOVELTY - Flexible fiber sweat sensor comprises a fibrous substrate on which a moisture-sensitive functional material is coated, where both ends of the fiber base are connected with conductive wires, or the middle of the fiber base is coated with a moisture-sensitive functional material, and both ends are coated with a conductive material, and the moisture-sensitive functional material is a complex material of a functional conductive material and a hydrophilic polymer. USE - The flexible fiber sweat sensor is useful for monitoring body surface humidity. ADVANTAGE - The flexible fiber sweat sensor has high fitness, can adapt to the bending surface of human body, low cost characteristics can realize the real-time monitoring of human surface humidity change, can be applied to human body health, large data and so on, has simple preparation, easy integration, signal is easy to distinguish, and has simple knitting into the daily fabric, with the daily wearing of the fabric with the same appearance, and is capable of freely deforming, through simple knitting method into the fabric can form sweat function of the sensing fabric.
