▎ 摘　　要

NOVELTY - Flexible graphene joint sensor comprises a graphene sensing unit provided on a first surface. An extensible wire structure, and the extensible wire structure includes a baseline layer and a conductive layer. The baseline layer is formed on at least part of the surface of the first surface. The conductive layer is formed on at least part of the surface of the baseline layer away from the first surface. The extensible wire structure is connected to the graphene sensing unit. An external conductor connected to the conductive layer in the extensible conductor structure. A second flexible layer, one surface of the second flexible layer is a second adhesive surface. The second adhesive surface is opposite to the first surface and cover the graphene sensing unit, the extensible wire structure, the first surface and part of the external wire. The area of the second adhesive surface is larger than the area of the first surface. USE - Used as flexible graphene joint sensor. ADVANTAGE - The sensor is an ultra-thin flexible device that can completely fit the skin and suitable for long-term wear; and has high reliability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for method for preparing a flexible graphene joint sensor. DESCRIPTION OF DRAWING(S) - The drawing shows a structural schematic representation of the flexible graphene joint sensor.
