Ink Jet Printing of Implantable Electrodes
First Claim
1. A method of producing an implantable electrode device, the method comprising:
- providing a electrode substrate for structural support;
developing an electrode network of wires and contacts by inkjet deposition of conductive metal material over portions of the electrode substrate for electrically connecting an implant processor device to targeted tissue in a patient; and
selectively covering a portion of the electrode network with a biocompatible encapsulation layer for providing electrical insulation for the covered portion of the electrode network, wherein the selectively covering leaves a plurality of exposed portions of the electrode network to allow electrical contact with adjacent tissue.

Abstract
An implantable electrode device and a corresponding method of fabricating such a device are described. An electrode network of wires and contacts is developed by inkjet deposition of conductive metal material over portions of the electrode substrate for electrically connecting an implant processor device to targeted tissue in a patient. An electrode substrate beneath the electrode network provides structural support to the electrode network. A biocompatible encapsulation layer selectively covers a portion of the electrode network and provides electrical insulation for the covered portion of the electrode network while leaving exposed portions of the electrode network which allow electrical contact with adjacent tissue.
