Researchers have created a device that generates electricity from our own body heat, and helps us to recharge electronic devices on the go.
The small and flexible generator, made from glass and fabric, can be used to power up heart monitors, smart glasses and other wearable tech, Daily Express reported.
According to the company, they are looking to develop it so that it can be used for devices such as Apple iPhone, Samsung Galaxy and the HTC range of smart phones.
Professor Byung Jin Cho from the KAIST University in South Korea, who is leading the team working on the thermoelectric (TE) generator, said the tech minimises thermal energy loss but maximises power output.
