▎ 摘　　要

NOVELTY - The method involves growing a graphene electrode layer (20) on a temporary substrate. A flexible substrate (40) is grown on one surface of the graphene electrode layer, which is far from the temporary substrate. The temporary substrate is removed while preserving the graphene electrode layer and the flexible substrate to form an electrode body (60) having a bio-electrode end (61), an interface-connection end (62) and a middle region between the bio-electrode end and the interface-connection end. An insulating layer (50) is used to wrap the middle region but expose the bio-electrode end. USE - Method of fabricating flexible microelectrode (claimed) for detecting neural signals to understand operation of nervous system for diagnosis, therapy and prosthesis design of neural diseases. ADVANTAGE - Graphene has biocompatibility much superior to that of ordinary metallic electrodes. The flexible substrate enables the electrode to bend, and the insulating layer protects the electrode from external interference. Provides microelectrode which features flexibility, high biocompatibility and high electric conductivity simultaneously. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a flexible microelectrode for detecting neural signals. DESCRIPTION OF DRAWING(S) - The drawing is a perspective view schematically showing the fabrication of a flexible microelectrode for detecting neural signals.
