3D multi-layer probe for application in neuroprosthetics

Diego Ghezzi, Marta Jole Ildelfonsa Airaghi Leccardi, Vivien Gaillet, Bastien Duckert

In neuroprosthetics, prostheses with higher and denser electrodes are needed to obtain both more precise recordings and targeted stimulations. The main limit is the routing of the active sites to the electronic control unit. A solution is to place electrod ...
