▎ 摘　　要

NOVELTY - A flexible sensor comprises a graphene cloth dielectric layer obtained by immersing cloth in a graphene slurry and drying, and a metal electrode arranged on the surface of the graphene cloth dielectric layer. USE - The flexible sensor is useful as pressure sensor and strain sensor (all claimed) for detecting life activity. ADVANTAGE - The flexible sensor has large working range, high sensitivity, and excellent stability, is non-toxic and environmentally-friendly, and can be prepared by a simple method without requiring reduction step. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the flexible sensor.
