Artificial Sensory Nerves May One Day Provide Prosthetic Limbs with Sense of Touch

Scientists from Stanford and Seoul National University say they have developed an artificial sensory nerve system that can activate the twitch reflex in a cockroach and identify letters in the Braille alphabet. The study (“ A bioinspired flexible organic artificial afferent nerve ”), published in  Science , is a step toward creating artificial skin for prosthetic limbs, to restore sensation to amputees and, perhaps, one day give robots some type of reflex capability, a
