Abstract: 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.

Abstract: Disclosed are a graphene oxide cochlear implant electrode and a manufacturing method thereof. The graphene oxide cochlear implant electrode includes an electrode tip, an electrode carrier, electrode contacts, a first positioning ring, a second positioning ring, a boosting portion, an electrode wire, a loop electrode, a loop electrode wire and a wire array, herein the electrode tip is arranged at a foremost portion of the cochlear implant electrode, the electrode carrier is silica gel grafted with a graphene oxide, the electrode carrier wraps the electrode wire and semi-wraps the electrode contacts connected to the electrode wire one by one, and the electrode carrier is slightly curved as a whole; and the electrode wire is connected to the electrode contacts one by one and forms a spiral shape through the first positioning ring, the second positioning ring and the boosting portion.
