Peripheral Nerve Electrodes

Abstract

Peripheral nerve electrodes, with the goal of restoring muscle functions or recording neural signals, have been extensively studied. Recently, not only have existing designs been re-scrutinized, but several new electrode designs have been developed. Despite several excellent comprehensive review articles on peripheral nerve electrodes, most of them focus on different types of devices but lack a systematic emphasis on the challenges and design motivations. In addition, more recent developments involve redesigning conventional electrodes, but these new advances have not been covered in any review article yet. Here, we review recent advances on peripheral nerve electrodes, by analyzing three major challenges and corresponding strategies, which may guide the community to a problem-driven path and inspire further innovations.
