Ultra thin sensors printed on skin to monitor health

Eliminating the elastomer backing makes the device one-thirtieth as thick, and thus “more conformal to the kind of roughness that’s present naturally on the surface of the skin,” says John Rogers at the University of Illinois. It can be worn for up to two weeks and can measure temperature, strain, and the hydration state of the skin, and also be used to monitor wound healing.
