Flexible electrode array for retinal stimulation

The retina interfacing and prosthesis project is a joint project between the Duke University Eye Center, NC State University, University of NC, and the Research Triangle Institute. The ultimate goal of the project is to design, build, and test a retinal prosthesis that would capture photons, electrically stimulate the retina, and thus generate a phosphene map (focal flashes of light) that would provide information about movement, light intensities, and edge detection to otherwise severely visually handicapped patients. This paper summarizes the design and fabrication of a flexible, biocompatible stimulating array to be connected to a photosensing chip with image processing capabilities.
