The energy from a beating heart can be harnessed to power a pacemaker, scientists have found.
A team of American researchers used piezoelectricity, which is produced from mechanical pressure, to convert energy from a beating heart. They generated enough electricity to power a pacemaker, according to the British Heart Foundation yesterday.
Piezoelectricity might also be able to power other implantable cardiac devices such as defibrillators, according to the new research.
