Abstract

The present invention provides an implantable electrode with increased stability having a clustered structure wherein the surface of the electrode is covered with a material comprising openings which are filled with sticks or posts. The present invention provides an implantable electrode with increased stability wherein the surface is of the electrode comprises mesh grids which are filled with sticks which are filed with a conducting or insulating material. The present invention provides a method of manufacturing an electrode with increased stability, comprising: depositing a metal layer on an base layer; applying photoresist layer on the metal layer; patterning the photoresist layer providing openings; electroplating the openings with metal; removing the photoresist layer leaving spaces; and filling the spaces with polymer. The present invention provides a method of manufacturing an electrode with increased stability, comprising: depositing a metal layer on an base layer; applying a polymer layer on the metal layer; applying photoresist layer on the polymer layer; patterning the photoresist layer providing openings; electroplating the openings with metal; and removing the photoresist layer.
