▎ 摘　　要

NOVELTY - Flexible graphene electrode, comprises a flexible substrate (10) arranged in sequence, a laser-induced graphene layers (20), a conductive polymer layers (30) and a flexible packaging layers (40), where the surface of the laser-induced graphene layer is in contact with the conductive polymer layer is first surface. The surface vertical to the first surface is the second surface and the second surface of the laser-induced graphene layer is modified with transition metal nano particles. USE - The flexible graphene electrode is useful in bioelectrode, biosensor or implanting medical device (claimed). ADVANTAGE - The electrode: has excellent biocompatibility, electrical performance, electrochemical performance, flexibility and mechanical characteristics. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a preparation method of flexible graphene electrode. DESCRIPTION OF DRAWING(S) - The drawing shows a side view of the flexible graphene electrode. 10Flexible substrate 20Laser-induced graphene layers 30Conductive polymer layers 40Flexible packaging layers
