Transform your body into a biological battery with a new wearable gadget

A modern, low-cost wearable technology has been created by researchers at CU Boulder that turns the human body into a biological battery.

The gadget is stretchy enough that you can wear it like a ring, a bracelet or some other accessory that touches your skin, as defined in the journal Science Advances. It also taps into the natural heat of a human, using thermoelectric generators to turn the internal temperature of the body into electricity.

“In the future, we want to be able to power your wearable electronics without having to include a battery,” said Jianliang Xiao, senior author of the new paper and an associate professor in the Paul M. Rady Department of Mechanical Engineering at CU Boulder.

This is just the first in creating a technology of any use to the average consumer but this could at some point pave the way for companies such as Apple, Samsung or Google to create a wearable such as a smart watch that doesn’t need to be taken off to charge. Imagine using your Apple Watch to track all your vitals and the heat your body generates could also be charging your watch, that would mean you could track your sleep, your exercise and your BP 24 hours a day.
