From Scientific American:
A new flexible electronic circuit promises to do just that, by moving with the skin and staying in place without any adhesive. The research used existing semiconductor technology to imprint integrated circuits onto a thin, flexible silicon film that can be applied directly on the skin. The device is described in a new paper published online August 11 in Science. “The goal is really to blur the distinction between electronics and biological tissues,” John Rogers, a professor of materials science and engineering at the University of Illinois at Urbana-Champaign (U.I.C.U.) and co-author of the new study, said in a podcast interview. The new technology might soon allow monitoring to become “simpler, more reliable and uninterrupted,” Zhenqiang Ma, a professor at the University of Wisconsin–Madison's Department of Electrical and Computer Engineering, wrote in an essay in the same issue of Science.
