Abstract

The present disclosure discusses a method of manufacturing an implantable neural electrode. The method includes cutting a metal layer to form a plurality of electrode sites, contact pads and metal traces connecting the electrode sites to the contact pads. A first silicone layer including a mesh is formed and coupled to the metal layer. A second silicone layer is formed and laminated to the first silicone layer coupled with the metal layer. Holes are formed in the first or second silicone layer exposing the contact pads and electrode sites. Wires are welded to the exposed contact pads and a third layer of silicone is overmolded over the contact pads and wires.
