Retinal Implant

• The purpose of the Retinal Implant Project is to
  restore useful vision to patients who are blind
  with degenerative retinal diseases.
• The CNF-fabricated components of this system have
  been the flexible circuit on which the remaining
  components of our prosthesis are assembled, and
  the stimulating electrode arrays themselves. Si
  wafers serve as carriers for these freestanding
  films during processing. The electrode leads are
  fabricated inside of a sandwich of polyimide or
  parylene-C, while the IrOx electrodes themselves
  are fabricated by reactive sputtering.
• Implant studies with these probes demonstrate
  continuing improvement in recognition
  capabilities as we improve our designs.
