Using Body Heat to Charge Wearables

Written By

The Korean Advanced Institute of Science and Technology, or KAIST, have reportedly invented a method to turn body heat into electricity. This could of course provide a great source of prolonged battery life to any wearables such as fitness trackers and smart watches, especially those worn during periods of extended exercise where core body temperature rises.

Using the body to create energy in wearable technology has been commercially available since at least the mid-1980’s when SEIKO unveiled its automatic quartz technology which leverages body movement to rotate a pendulum and create energy. Body heat powering wearable technologies have also been in existence for some time now, but KAIST is claiming their most recent method can produce up to ten times the energy output as existing generators.
