Intrafascicular thin-film multichannel electrodes for sensory feedback: Evidences on a human amputee

Abstract

The performance of motor neuroprostheses or robotic arm prostheses can be significantly improved by delivering sensory feed-back related to the ongoing motor task (e.g. the slippage of an object during grasping). Microfabricated neural electrodes implantable in peripheral nervous system seem a promising approach to this aim. New generation of thin-film intrafascicular electrodes longitudinally implantable in peripheral nerves (tf-LIFE4) has been developed and tested for afferent stimulation in human amputee case study.
