Imec Introduces World’s First Thin-Silicon Implantable Chip for
  High-Precision Haptic Prosthetics
From: Medcial Design Briefs - 07/2017 - page 37

Imec announced its success in fabricating a prototype implantable chip that
aims to give patients more intuitive control over their arm prosthetics. The
thin-silicon chip is a world’s first for electrode density and was developed
in collaboration with researchers at the University of Florida, as part of
the IMPRESS project funded by the DARPA’s HAPTIX program to create a
closed-loop system for future-generation haptic prosthetics technology.
