In this project the Hector Fellows Jürg Leuthold and Eberhart Zrenner are working together with the HFA Postdoc Dr. Wadood Haq (Eberhard Karls University, Tübingen) and doctoral students Shadi Nashashibi (ETH Zurich) and Marina Homs (ETH Zurich) towards the next generation of retinal implants. By combining highly sensitive photodetectors with a microelectrode array operating under a new stimulation paradigm, the RetinaSensor will enable previously unachieved spatial and temporal resolution in electric retinal implant technologies.
