'Bionic skin' could help robots interact

LOS ANGELES - Researchers have developed a "revolutionary" process for 3-D printing stretchable electronic sensory devices that could give robots the ability to feel their environment.

The discovery, published online in the journal Advanced Materials, is a major step forward in printing electronics on real human skin, say researchers.

The new process was developed by engineers at the University of Minnesota in the United States using a 3-D printer they built in a lab.
