Wrist strap that converts body heat into electricity    Beijing:Experts have developed a wrist strap that can currently illuminate an LED from body heat. The wrist strap generates electricity using the Thermo Electric Generator (TEG) principle. In the future, the same technology will power smartwatches and wearable devices, and the need for batteries may be eliminated. It was invented by Professor Chian Zheng and his colleagues at the Harbin Institute of Technology in China. Chian says the invention will help solve battery and power problems. It should be noted that Qian Zheng has been working on TEG technology for 15 consecutive years. Although TEGs are very hard and solid, Chian says he made a strip of magnesium and bismuth from polyurethane and made all the electrodes flexible.
