Researchers at the universities developed a bio-friendly energy storage system called a biological supercapacitor; it’s harmless to the biological systems in the body. The device could enable cardiac pacemakers and other implantable medical devices that last longer.
Pacemakers are small battery-powered devices that help the heart beat in a regular rhythm. They create electrical impulses that help stimulate the heart to beat, according to the American Heart Association. A pacemaker has a sensing mode that allows it to send impulses when the heartbeat is above a certain level and can fire when the heartbeat is too slow. However, the batteries need to be replaced after awhile, which forces the patient to undergo another surgery.
