Artifact-Free Stimulation for Next-Generation Single-Cell Resolution Epiretinal Implants

Implantable epiretinal prostheses aim to restore visual capability for patients suffering from diseases such as Macular Degeneration and Retinitis Pigmentosa by bypassing damaged photoreceptors and electrically exciting Retinal Ganglion Cells (RGCs) directly. Next-generation devices will require single-cell resolution, and bidirectional...

OPTOEPIRET: Development of a exible epiretinal implant dummy with through-connections in the polyimide substrate

Millions of people suffer from retinal diseases worldwide. Retinal diseases can either be cured or treated. Retinal implants try to do the latter and aim to restore, partially, the vision in visually impaired people. This research thesis introduces a flexible implant with through-connections and a corresponding thinned silicon dummy chip that,...
