Abstract

See full text

The present invention discloses a graphene cochlear implant electrode and a fabrication method thereof. The electrode comprises a tip portion, bendable portions, contact electrodes, an electrode carrier and wire electrodes, wherein the tip portion is disposed at forepart of the cochlear implant electrode, the electrode carrier wraps the wire electrodes and half wraps the contact electrodes connected to the wire electrodes one by one, and each bendable portion is an annular groove disposed on the electrode carrier; each contact electrode comprises an inner contact and an outer contact, when bending, the inner contact faces the modiolus while the outer contact faces away from the modiolus; and each wire electrode is wavy. According to the present invention, the graphene cochlear implant electrode enhances the surface bioactivity of the contact electrodes to facilitate cell adhesion, proliferation and differentiation, while promoting its formation and integration with peripheral nerves as an implant material, thus improving the surface bioactivity and biocompatibility of the contact electrodes of a cochlear implant.
