Pain-Sensing e-dermis Electronic Skin

Pain-Sensing e-dermis Electronic Skin
The e-dermis electronic skin could give prosthetics a sense of touch—and pain.

Developed by a team from Johns Hopkins University and the Singapore Institute of Neurotechnology, the e-dermis is made up of an array of electronic sensors that have been embedded in a fabric and rubber material. Sensations are relayed through the skin via non-invasive transcutaneous electrical nerve stimulation, providing a range of feelings from a fine touch to “uncomfortable yet tolerable” pain. By allowing the prosthetic to detect a level of pain, the device could provide more natural feelings while also protecting itself from damage.
