▎ 摘　　要

NOVELTY - Preparing flexible graphene electrode involves providing graphene layer formed on substrate. The carbon-containing fibers are introduced on surface of graphene layer by spinning treatment, and carbonized fiber layer formed on surface of graphene layer is obtained by annealing treatment. The surface of carbonized fiber layer is coated with polymer solution, solvent is evaporated to obtain flexible layer in which carbonized fiber layer is partially embedded. The substrate is removed by etching to obtain the flexible graphene electrode. USE - Method for preparing flexible graphene electrode used as a skin electrode for detecting electrophysiological signals (claimed) on human skin,, which is stretched and changed simultaneously with skin movement changes during maintainance of functional integrity and wearing comfort, and for the development of sports science, human-computer intelligent interaction, health monitoring, medical rehabilitation and other fields of great significance. ADVANTAGE - The flexible graphene electrode is firm and durable, and has good conductive performance. The carbonized fiber layer interact with graphene to improve the overall conductivity of the electrode. The flexible graphene electrode is used for electrophysiological signal detection on human skin, maintain a high signal-to-noise ratio after repeated use, and has a good application prospect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a flexible graphene electrode, which comprises graphene layer, carbonized fiber layer formed on surface of graphene layer, and flexible layer is formed on surface of carbonized fiber layer, where carbonized fiber layer is partially embedded in flexible layer. DESCRIPTION OF DRAWING(S) - The drawing shows flowchart of a method for preparing flexible graphene electrode. (Drawing includes non-English language text).
