Electrical signals can be recorded using long-term implanted nerve cuff electrodes in human peripheral nerves. Reliable detection of sensory nerve signals is essential if such signals are to be of use in sensory-based functional electrical stimulation neural prosthetics as a replacement for artificial sensors (switches, strain gauges, etc.). In this review, the signal characteristics of the sensors, the nerve interface, signal processing, and an example of human application to restore motor functions are described.
