Multi-microelectrode devices for intrafascicular use in peripheral nerve

Abstract

This minisymposium paper gives an overview of experimental, modeling, design and microfabrication steps which lead towards the University of Twente threedimensional 128-fold silicon microelectrode device. The device is meant for implantation in peripheral nerve for neuromuscular control purposes and is estimated to be able to selectively control 10-20 motor fibres. Also, the potentialities of a n alternative LIGA microfabrication technology are considered.

Implantable FES Stimulation Systems: What is Needed?

“…This was based on the distances between nodes of Ranvier (7). In a subsequent study (8), he tested a 128‐electrode brush with a 2‐dimensional array that had electrodes in a square grid with a separation of 120 μm. However, following implantation it was found that only 10–20 motor units were accessible, fewer than 20% of the number of electrodes.…”
