Your hot body could soon power wearable batteries. How cool is that!!

Author: Aman Gupta


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 to create energy using the temperature differential between the wearer's body and the air around them.



Previous attempts at a matrix-style human battery have used bulky, low yield heat sinks to store body heat. Thermoelectric generators generate 20 times as much power while remaining  more comfortable and light-weight. Using a polymer that can be applied to both skin and fabric.

The thermoelectric generators can  generate upto 20-watt power per square centimeter, meaning more can potentially yield more power depending on where it is located.



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 smartwatch that could keep going just by sapping your body temperature.
