Stretchable electronics

WFMZ-TV (Penn., July 20) -- "We've been able to create a new class of materials that we call stretchable electronics," said Marvin Slepian, associate department head of biomedical engineering at the University of Arizona. Slepian figured out how to put thin electronics into materials that move with the body. This bio stamp sends metrics on heart rate, movement and more to an iPad in real time. Slepian is working in collaboration with researchers at the University of Illinois, Tufts, and Northwestern. They've also developed a wearable sweat sensor that can track electrolytes and hydration. It could be used for athletes and for soldiers in the field. Also: NBC5-TV (Dallas, TX, July 7), WNDU-TV (South Bend, Ind., July 20), ASEE FirstBell (July 21).
