Self-healing plastic ‘skin’ feels touch


A new type of synthetic “skin” is the first material that can both sense subtle pressure and heal itself when torn or cut.

The Stanford University researchers took a thin strip of the material and cut it in half with a scalpel. After gently pressing the pieces together for a few seconds, the researchers found the material gained back 75 percent of its original strength and electrical conductivity. The material was restored close to 100 percent in about 30 minutes.

“Even human skin takes days to heal. So I think this is quite cool,” says researcher Benjamin Chee-Keong Tee.
