Polymer-based longitudinal intrafascicular electrodes (polyLIFEs) were chronically implanted into the sciatic nerve of white New Zealand rabbits (n=8) for a period of 6 months (hereafter referred to as the long-term group). The impact of the implanta

A closed-loop control system for controlling the key grip of a C6 tetraplegic patient was developed. Natural sensors served as the source of the feedback signal. The neural signals from cutaneous receptors were picked up by an implanted cuff electrod

C5 and C6 quadriplegic individuals lack motor and sensory function in their hands. Hand grasp can be partially restored using functional neuromuscular stimulation, but controlling the synthesized grasp is hindered by the absence of tactile or proprio

Recording cuffs used to register the activity of sensory afferents in peripheral nerves hold promise to provide feedback signals for closed-loop FES systems. This paper compares two modes in which the electrodes of a tripolar nerve cuff may be connec
