, discusses study results presented at AHA 2012 that demonstrated the technical feasibility of using a piezoelectric energy-harvesting device to power a pacemaker, potentially showing the way to a batteryless future for implantable cardiac devices. The nonlinear piezoelectric device used in the study generated sufficient power from heart rates of 20-600 beats per minute to power a pacemaker. Karami said that development of this technology promises to decrease size and increase longevity and functionality of cardiac implanted electrical devices.
