A 3D microelectrode array to record neural activity at different tissue depths

Measuring neuronal responses along all three spatial dimensions is the next step, beyond the capacity of established 2D microelectrode arrays (MEAs), to record electric activity inside tissues with highly accurate spatial resolution. This research presents silicon-based planar arrays of 3D microelectrodes, whereby each microelectrode supports...

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,...
