Human Skin

SEOUL, Sept 9 (Reuters) - South Korean researchers say they have developed an artificial skin-like material, inspired by natural biology, that can quickly adjust its hues like a chameleon to match its surroundings. The team, led by Ko Seung-hwan, a mechanical engineering professor at Seoul National University, created the "skin" with a special ink that changes colour based on temperature and is controlled by tiny, flexible heaters.
