Battery-free pacemaker powered by the heart itself

Scientists are developing next-generation battery-free implantable pacemakers that may be powered by an unlikely source, the heart itself. The advancement is based upon a piezoelectric system that converts vibrational energy, created inside the chest by each heartbeat, into electricity to power the pacemaker. "Essentially, we're creating technology that will allow pacemakers to be powered by the very heart that they are regulating," said M Amin Karami, assistant professor of mechanical engineeri...
