Temporary tattoos that alert a doctor if a premature baby's heart rate is irregular, or if a diabetic's blood sugar is too high--this sounds like the stuff of science fiction, right? Health Wearable startup MC10 is making it a medical reality. Back in 2008, John Rogers--a materials scientist and director of the Frederick Seitz Materials Research Laboratory at the University of Illinois at Urbana-Champaign and a 2009 MacArthur Fellow, to boot--invented the stretchable circuit. The thin, flexible devices make it possible to take electronic components places an old school rigid circuit board can't go--like the surface of your skin. Rogers and Carmichael Roberts co-founded MC10 to bring these innovations to market and "make humans more superhuman." After success in the sports and fitness field, the company has turned its attention to health care. The latest innovation is the Biostamp, a second skin patch that monitors biomedical data and wirelessly transmits it to the four Ps of health care: patients, physicians, providers, and payers. MC10 spent 2015 testing it with entities as disparate as the University of Rochester, the Air Force, and cosmetics company L'Oréal, and is set to release its newest consumer-facing innovation in early 2016.
