Your Body Heat Could Power Your Devices: How Wearable Thermoelectric Generators Work
Imagine charging your smartphone simply by wearing a bracelet, or powering medical sensors with nothing more than your body heat. Wearable thermoelectric generators make this possible by converting the temperature difference between your skin and the surrounding air into usable electricity. This emerging technology works on a principle called the Seebeck effect, where heat flowing through special semiconductor materials creates an electric current without any moving parts or batteries required.
Unlike wearable solar panels…
