Attempting to free people with diabetes from frequent finger-pricks and drug injections, researchers have created an electronic skin patch that senses excess glucose in sweat and automatically administers drugs by heating up microneedles that penetrate the skin.
The prototype was developed by Dae-Hyeong Kim, assistant professor at Seoul National University and researchers at MC10, a flexible-electronics company in Lexington, Massachusetts. Two years ago the same group prototyped a patch aimed at Parkinson’s patients that diagnoses tremors and delivers drugs stored inside nanoparticles.
