Nerve Interface for Direct Sensory Feedback
From: Medical Design Technology - 06/20/2013

Researchers at Case Western Reserve University used a flat interface nerve
electrode (FINE) to demonstrate direct sensory feedback. By interfacing with
residual nerves in the patient's partial limb, some sense of touch by the
fingers is restored. Other existing prosthetic limb control systems rely
solely on visual feedback. Unlike visual feedback, direct sensory feedback
allows patients to move a hand without keeping their eyes on it—enabling
simple tasks, like rummaging through a bag for small items, not possible with
today's prosthetics.
