▎ 摘　　要

NOVELTY - Preparing flexible sensor electrode comprises providing a graphene monoxide film, performing silane modification on the graphene oxide film to obtain modified reduced graphene oxide film, coating a medium material on one side of the modified reduced graphene oxide film to make the medium material adsorb on the modified reduced graphene oxide film, and modifying the biological enzyme on the surface of the modified reduced graphene oxide film on which the medium material is adsorbed. USE - The method is useful for preparing flexible sensor electrode. ADVANTAGE - The method: has a simple process; can tightly combine the media layer and the electrode body; and realizes the flexibility of the sensor electrode. DETAILED DESCRIPTION - INDEPENDENT CLAIM are also included for: (1) flexible sensor electrode; and (2) flexible sensor. DESCRIPTION OF DRAWING(S) - The drawing shows a flow chart of the process of preparing flexible sensor electrode (Drawing includes non-English language text).
