Scientists have developed a polymer that can stretch to about hundred times its length and can even self-heal at room temperature.

The top layer featured a sensor that can detect pressure over the same range as human skin, from a light finger tap to a firm handshake.

Scientists have invented a battery electrode that heals itself, paving way for long-lasting batteries for all electronic devices.

John Rogers was in his lab at the University of Illinois at Urbana-Champaign six years ago, testing new ways to make electronic circuits.
