New Wearable Microgrid Turns Your Sweat Into Energy! Human Movements Can Now Power Small Devices

Engineers successfully developed a new wearable microgrid that could transform a human's sweat into energy. This means that you can create energy by running, walking, jogging, or any physical movement if you use this.

The engineers showed that the energy generated by the new wearable tech was enough to power an LCD wristwatch or a small electrochromic display, which is a device that changes color in response to an applied voltage.

"We're applying the concept of the microgrid to create wearable systems that are powered sustainably, reliably, and independently," said Lu Yin, the co-first author of the study and a nanoengineering Ph.D. student at the UC San Diego Jacobs School of Engineering, via E&T Magazine.

"Just like a city microgrid integrates a variety of local, renewable power sources like wind and solar, a wearable microgrid integrates devices that locally harvest energy from different parts of the body, like sweat and movement, while containing energy storage," added the engineer.

Where will you put it?

The new wearable microgrid is specifically designed to harvest your sweat. This means that its biofuel cells need to be put inside the user's shirt, specifically at the chest part. On the other hand, its triboelectric generators are placed outside the shirt on the torso's forearms and sides near the waist. If you want to know more details, just click here.
