It’s the stuff of science fiction: using your own body to power your electronics. And yet it is finally here.
Researchers at CU Boulder have developed a new, low-cost wearable device that is stretchy enough that you can wear it like a ring, a bracelet, or any other accessory and it transforms the human body into a battery.
“In the future, we want to be able to power your wearable electronics without having to include a battery,” said in a statement Jianliang Xiao, senior author of the new paper and an associate professor in the Paul M. Rady Department of Mechanical Engineering at CU Boulder.
His new devices can generate about one volt of energy for every 0.155 sq in (1 sq cm) of skin space, enough to power electronics such as watches. The wearables tap into a person’s natural body heat, using thermoelectric generators to convert the body’s internal temperature into electricity. Even better, the device can heal itself…
