▎ 摘　　要

NOVELTY - The film has a conductive layer arranged on a substrate layer. The conductive layer is provided with a wave-shaped structure. The wave-shaped structure is provided with a first wave-shaped structure and a second wave-shaped structure. The first wave-shaped structure is provided with a first wave-shaped structure and a second wave-shaped structure. The second wave-shaped structure is provided with a first wave-shaped structure and a second wave-shaped structure. USE - Flexible conductive film for use in a flexible resistance pressure sensor of a flexible electronic device. ADVANTAGE - The contact area of the electrode and the wave structure is increased while applying pressure so as to reduce resistance and use the film as a flexible resistance pressure sensor. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) a flexible conductive film preparation method ; (2) a flexible electronic device; (3) a modified graphene material; (4) a modified graphene material preparation method; and (5) a conductive film. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the flexible conductive film.
