Body Heat Today

: 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"

: Modern TEGs can power small electronics like smartwatches (e.g., MATRIX PowerWatch) and fitness trackers without ever needing a battery [6, 18]. Body Heat

: Heat is a byproduct of metabolism—the chemical reactions that convert food into energy [1, 17]. : To keep enzymes functioning properly, the body

: New research has produced 3D-printable, stretchable fabrics that can power medical sensors or LEDs just by touching the skin [8, 11]. : To keep enzymes functioning properly
