Researchers from Carnegie Mellon University have presented an innovative technology called Power-Over-Skin. It is capable of turning the human body into a conductor for electricity.

In their experiments, the scientists used a battery-powered transmitter that successfully transferred power to small devices such as a Bluetooth joystick in a ring and a glowing earring.

Power-Over-Skin technology has the potential to free devices from bulky batteries. In the long run, it could make medical devices such as glucometers and pacemakers more miniaturized and self-contained. The devices could be integrated into accessories - such as earrings or bracelets - that would be invisible to users.

At the moment, the technology can only power low-power devices such as LEDs. However, the team of scientists plans to increase the development power by 10 times to power more sophisticated devices, including wireless headphones
