Scientists from the United States have developed a mini-wearable device technology that is capable of charging up using heat from the human body.
The low-cost wearable device, developed by a team at the University of Colorado Boulder, is stretchy enough and can be worn as a ring or a bracelet. It features generators to convert the body’s internal temperature into electricity. According to research published in the journal Science Advances, the new device is able to treat the human body as a biological battery, taking its required power only from the body heat.
The wearable device employs thermoelectric generators to convert the body’s internal temperature into electricity. Jianliang Xiao, a professor of mechanical engineering at the university who came up with the idea, believes it could be on the market within five to 10 years
