Engineers are developing —thin, flexible materials that convert the temperature difference between your skin and the air into electricity [3, 15].
Your body is a walking furnace. Every square foot of human skin releases heat equivalent to about [1]. Body Heat
: To keep enzymes functioning properly, the body must stay within a narrow temperature range [14]. When you get cold, your body uses brown fat or shivering to generate extra warmth [4]. When you overheat, the hypothalamus triggers sweating and vasodilation (rushing blood to the skin) to release excess heat [9]. The Technology: Harvesting "People Power" Engineers are developing —thin
: Heat is a byproduct of metabolism—the chemical reactions that convert food into energy [1, 17]. Body Heat
