▎ 摘  要

NOVELTY - The method involves obtaining a precursor structure of a neural microdelectrode, where the precursor structure is comprised a substrate, a first insulating layer, a signal transmission unit and an electrode recording point supporting body. The first insulation layer and the signal transmitting unit are sequentially stacked on the upper surface of the substrate. An electrode recording points is embedded the supporting body in the area of the first insulation layer that is not covered by the signal transmitter unit. A graphene to-be-processed is removed form a graphene signal collecting unit. A patterned light-emitting photoresistor is removed to obtain a re-processing structure. A second insulation layer is formed. The electrode record point support body is etched and removed. The substrate is seperated from the substrate to obtain the final product. USE - Method for preparing a nerve microelectrode used as nerve electric signal collecting device for recording nerve activity state, used for detecting brain function structure, constructing nerve loop map. ADVANTAGE - The method enables avoiding the etching damage, and improves the graphene success rate of recording point of electrode. The electrode recording point supporting body is etched away to expose it, protecting it from damage and has integrity. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart illustrating of a method for preparing a nerve microelectrode (Drawing includes non-English language text).
