According to a research paper published earlier this month, the supercapacitor is made up by a device called a “harvester” that operates by using the body’s heat and movements to extract electrical charges from ions found in human body fluids, such as blood, serum, or urine.



Researchers argue that implantable medical devices using their supercapacitor could last a lifetime, and remove the need for patients to go through operations at regular periods to replace batteries, one of the main causes of complications with implantable medical devices.

Currently, the supercapacitor looks primed to be deployed with pacemakers, but researchers hope their technology could be used with other devices that stimulate other organs, such as the brain, the stomach, or the bladder.
