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.
