New Technology Uses Body Heat to Charge Smartphones

Keeping your smartphone charged is a challenge, but that problem may be eliminated with a revolutionary new product being developed in South Korea.

A team of scientists from the Korea Advanced Institute of Science and Technology (KAIST) is working on a product that could charge your phone with body heat.

Professor Byung Jin Cho and his associates are working on a thermoelectric generator which converts the small temperature difference between skin and air into energy. That energy could be used to charge smartwear devices, such as watches and glasses, or medical devices like heart monitors. As the technology develops, they hope to make it available for smartphones.

There are forms of thermoelectric generators on the market already, both in organic and inorganic forms. They all come with certain issues, and Cho’s design has combined their principles to eliminate most of those problems. The generators minimize thermal energy loss and maximize power output at the same time.

“This is quite a revolutionary approach to design a generator. In so doing, we were able to significantly reduce the weight of our generator, which is an essential element for wearable electronics,” said Cho.

There is no launch date for a smartphone charger at this time.
