▎ 摘　　要

NOVELTY - The method for preparing a fabric sensor involves: modifying the surface of the fabric by using chitosan; adsorbing graphene oxide by using the modified fabric; reducing the graphene oxide adsorbed on the fabric to obtain a conductive fabric; and performing functional treatment on the conductive fabric. The chitosan is modified by immersing the fabric in a chitosan-acetic acid solution. USE - Method for preparing a fabric sensor used for monitoring and evaluating activities on a part of a human body (claimed). ADVANTAGE - The fabric sensor has excellent sensitivity, excellent photo-thermal effect and waterproof, hydrophobic and self-cleaning functions. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) the fabric sensor; and (2) use of the fabric sensor, where the fabric sensor is cut out and sewn into a sport pad with copper wire as a sewing thread, for monitoring and evaluating activities on a part of a human body.
