Pacemaker Powered by Beating Heart

An interdisciplinary research team from Northwestern University, Evanston, IL, the University of Illinois, Urbana-Champaign, and the University of Arizona, Tucson, has developed a flexible medical implant that harvests energy from the beating heart, which, they say, could be used to power pacemakers, defibrillators, and heart-rate monitors naturally and reliably and reduce or eliminate the need for batteries.
