Check out the recent article in the Washington Post [link] on SML’s new “Terminator Skin”. The skin is made up of soft and stretchable circuitry that spontaneously restores its electrical connections when damaged. The material is composed of microscopic droplets of liquid metal (a eutectic alloy of gallium and indium; EGaIn) embedded in a soft silicone matrix. A scribe is used to selectively rupture the droplets and cause them to form electrically conductive pathways within the silicone. When the material is cut, torn, or punctured, droplets around the damaged area spontaneously rupture to form new conductive pathways.
