Abstract
An optical electrode having a plurality of electrodes, including a recording electrode having a roughened surface and an optical light source configured to emit light, wherein at least a portion of the light impinges on the recording electrode. Also disclosed are methods of producing an optical electrode and an opto-electronic neural interface system.
Claims13
An apparatus, comprising:
- a carrier;
- an electrode disposed on the carrier, wherein the electrode is configured to sense and record neural signals in a body tissue, and wherein the electrode has a roughened surface;
- and
- a light source disposed on the carrier, wherein the light source is configured to emit light to illuminate at least a portion of the body tissue, wherein at least a portion of the light is directed at the roughened surface of the electrode.
1 more element
An apparatus, comprising:
- a carrier;
- a recording electrode and a stimulation electrode each disposed on the carrier,
- wherein the recording electrode is configured to sense and record neural signals in a body tissue,
- wherein the stimulation electrode is configured to provide electrical stimulation to the body tissue,
- wherein the recording electrode comprises a roughened external material having a back side attached to an electrically conductive material to thereby provide the recording electrode with a roughened surface forming a front side of the roughened external material,
- and wherein the roughened surface has an average roughness greater than 10 nanometers;
- and
- a light source disposed on the carrier, wherein the light source is configured to illuminate at least a portion of the body tissue and the roughened surface of the recording electrode.
