▎ 摘　　要

NOVELTY - The sensor comprises has a flexible substrate (1), a micro-structure bottom layer (2), an electrode (3), a graphene film (4) and a flexible packaging layer (5). The flexible packaging layer and the flexible substrate are arranged in parallel. The lower surface of the flexible packaging layer is attached with a graphene film. The lower surface of the graphene film is provided with two electrodes which are not contact each other. The upper surface of the flexible substrate is provided with a micro-structure bottom layer, and the micro-structure bottom layer and the electrode are contact each other. USE - Flexible graphene pressure sensor for sensing flexible electronic device. ADVANTAGE - The flexible graphene pressure sensor has good flexibility, short response time, simple preparation method and high sensitivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of flexible graphene pressure sensor. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a flexible graphene pressure sensor.
