Electronic skin that lets prosthetic limbs "feel"

The "e-dermis" was invented by Johns Hopkins University researchers. It's an electronic skin that fits over the fingers of a prosthetic hand, and allows amputees to feel pain and pressure.

No one likes pain, but it serves a purpose: it protects us from injury. Pain tells us when to drop sharp or hot objects that could hurt us. Prosthetic limbs don't have that protection because they can't transmit the sensation of pain, which makes prosthetics particularly susceptible to damage. That's where the e-dermis comes in.
