This wearable is capable of turning your body into a battery | Digital Trends Spanish



Tired of carrying your charger everywhere? Don’t worry, it is possible that, in the future, your own body works like a battery.

At least that’s how researchers at the University of Colorado at Boulder have thought, who have developed a new portable (or wearable) device that turns a human body into a biological battery.

The innovative device, presented in the journal Science Advances, is elastic enough to be used as a ring, a bracelet or any other accessory that is in contact with the skin.

Thus, it takes advantage of a person’s natural heat, through thermoelectric generators, to convert the internal temperature of the body into electricity.

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

At the moment, this device can generate about one volt of energy for each square centimeter of skin, that is, less voltage per area than that provided by most of the batteries that exist.

Still, according to the researchers, it’s enough to power electronic gadgets like watches or fitness trackers.

“Every time you use a battery, you are draining it and, at some point, you will have to replace it. The nice thing about our thermoelectric device is that you can wear it and it provides you with constant power, ”adds Xiao.

Finally, the scientist estimates that his novel invention should take between five and ten years to be available on the market.
