A Korean developed battery that can be recharged using body heat has won a Netexplo Award, Unesco’s list of the top 10 digital innovations of the year, the organization said Thursday. A research team from the Korea Advanced Institute of Science and Technology (Kaist) led by electrical engineering Prof. Cho Byung-jin demonstrated the technology in April.

Netexplo Awards are given annually to tech inventions worldwide that have had a major influence on human lives in areas such as energy, environment and education. About 200 IT experts vote to pick 10 winners.

The battery, which Kaist said can be installed in a wearable device, is the first of its kind that recharges automatically when worn. The battery is made of fiberglass with a thin piece of thermoelectric film and must be attached to the part of the wearable that comes in contact with skin. It can be used in pedometers or smartwatches. After the battery is removed from the heat source, on a simple activity tracker, the Kaist battery will last twice as long as batteries that are currently used. But in a smartwatch, which has a larger display and more functions, the Kaist battery will last up to 30 percent longer once it is not being worn.
