Abstract
Visual prostheses with a high number of el ectrodes
are now of great research interest driven by the successful re-
cent clinical trials. High channel devices are confronted with
numerous challenges many of which can be add ressed by adopting
a multi-implant architecture. However now the dif ficulties lie in
ensuring safety of the inter-imp lant interface by addressing the
associated risks, often neglected in the past. This paper presents
a multi-implant architecture-ba sed 98-channel neurostimul
