Korean and American experts introduced an artificial skin outside the prosthetic hand, which can help people with disabilities to feel their surroundings or handshakes from others.
"In the past, robots or hands, artificial legs were not designed with high resolution skin and sensitive sensors with stress, pressure, or temperature, humidity. We focused on knots. Next to this is by developing a range of sensors with high sensitivity and density, creating a feeling similar to real human skin, " said CBS News, Kim Dae-Hyeong, a member of the research team.

Smart skin wrapped around the fake hand like a glove. It is made from soft elastomer material with elastic properties, containing temperature, humidity, pressure sensors and nerve stimulating electrodes.
The reaction effect of this skin layer is demonstrated by experiments that catch the ball, hold a cup of hot or cold water, touch a toy doll with human body temperature. When shaking hands or placing a hand on a baby's abdomen, a false hand can bring a familiar warm feeling. Smart skin also has a durable design and flexibility that resemble natural skin.
Expert Robert D. Gregg of the University of Texas identified this as an important technological advance in the study of human prostheses. They will continue to study other complex sensor arrays before they can be widely introduced.
