▎ 摘　　要

NOVELTY - A highly sensitive humidity responsive fiber comprises a composite fiber structure formed by conductive nanomaterials, hydrophilic polymers and hygroscopic salt. The hydrophilic polymer is coated on the surface of the conductive nanomaterial network to form a hydrophilic polymer coating layer. The hygroscopic salt is uniformly embedded in the hydrophilic polymer coating layer on the surface of the conductive nanomaterial network. USE - Highly sensitive humidity responsive fiber used for preparing humidity sensor such as wearable humidity sensor (all claimed). ADVANTAGE - The fiber has excellent strength and toughness, and rapid response to humidity, and can realize the real-time monitoring of local humidity conditions of fabrics. The fiber is combined with fabrics by simple method. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) manufacture of highly sensitive humidity responsive fiber; and (2) wearable humidity sensor, which comprises the highly sensitive humidity responsive fiber and a fabric combined with the highly sensitive humidity responsive fiber.
