Scientists just figured out how to turn your body into a battery
PACEMAKERS, DRUG DELIVERY PUMPS, Fitbits, and other wearable devices could soon run on a new kind of renewable energy: you.
A tiny new wearable gadget called a thermoelectric generator (TEG) directly turns your body’s heat into electrical energy. TEGs use a difference in temperature – such as your body’s temperature versus the surrounding air – to turn that energy into power. To establish equilibrium, heat automatically dissipates into cooler locations, and TEGs harness the electric current produced when energised particles
