The brand-new devise was recently presented during the AIP Publishing Horizons – Energy Storage and Conversion virtual conference, dedicated to new energy technologies, which brings together researchers from various countries to exchange experiences of future breakthroughs.

‘If the practical force of the heart is 0.5 newtons, the output power should be about 192 microwatts; therefore, for the commercial pacemaker, just about no less than 10 microwatts is sufficient for its normal work,’ researcher Yi Zhiran said.

He stressed that the key difference is the method of the power supply, as today’s pacemakers rely primarily on batteries and leads to keep the heart beating regularly.

‘A battery-less pacemaker is feasible through using implantable energy harvesting technology, which provides a sustainable power supply method,’ Yi said.
