A simple body-integrated self-powered system (BISS) can convert mechanical motions of the human body into electrical energy by exploiting the triboelectric effect. The device works without the need for complicated structures or high-cost production and maintenance thanks to research by a team in China, led by Zhou Li and Zhong Lin Wang at Beijing Institute of Nanoenergy and Nanosystems.

In the paper published in ACS Nano, they show how the BISS can power wearable and implantable devices. Flexibility in the choice of material, size and dimension offers a plethora of possible applications. Among them, the BISS could be integrated into wearable electronic devices, such as smart glasses or wristbands or implanted devices like cardiac pacemakers.
