Researchers at North Carolina State University have developed a new system that can convert the heat given off by your body into usable electricity.
The system uses thermoelectric generators, or TEGs, to create energy using the temperature differential between the wearer's body and the air around them.
Practical applications
Developed in part with the National Science Foundation's Nanosystems Engineering Research Center for Advanced Self-Powered Systems of Integrated Sensors and Technologies (whew), the TEG system was primarily designed for medical implements.
"The goal [...] is to make wearable technologies that can be used for long-term health monitoring, such as devices that track heart health or monitor physical and environmental variables to predict and prevent asthma attacks," says Daryoosh Vashaee, an associate professor at NC State. "To do that, we want to make devices that don't rely on batteries.
It would take some serious refinement, but we would love to see a body heat-powered battery making its way to commercial products, such as a smartwatch that could keep going just by sapping your body temperature. Too bad we'd probably also have to build up a sweat first, huh?
