electronic skin tattoo has medical, gaming, spy uses

'epidermal electronic system' monitors heart, brain activity...

from afp: A hair-thin electronic patch that adheres to the skin like a temporary tattoo could transform medical sensing, computer gaming and even spy operations, according to a US study published Thursday. The micro-electronics technology, called an epidermal electronic system (EES), was developed by an international team of researchers from the United States, China and Singapore, and is described in the journal Science. "It's a technology that blurs the distinction between electronics and biology," said co-author John Rogers, a professor in materials science and engineering at the University of Illinois at Urbana-Champaign. "Our goal was to develop an electronic technology that could integrate with the skin in a way that is mechanically and physiologically invisible to the user."
