Researchers have made great progress in prosthetics development in recent years, and a team in Korea and the United States have pushed things even further. Amputees will be able to better experience the world around them by using prosthetics equipped with "smart skin," able to allow them to feel sensations.
The unique elastomer soft polymer has integrated temperature, pressure and humidity sensors, along with electrodes that are able to stretch and stimulate the patient's existing nerves. Trying to develop technology able to send control commands from the nervous system to the prosthetic - and sensory feedback from the prosthetic back to the nervous system has proven to be difficult.
"Previously, these robots or prosthetic arms/legs did not have skins that enable high resolution/sensitivity sensing of pressure, strain, temperature, humidity," said Kim Dae-Hyeong, author co-study, in a statement to CBS News. "We focused on this point by developing high density/sensitivity sensor array that is similar with the real human skin."
