Power-Over-Skin technology paves the way for wearables without batteries

Carnegie Mellon researchers have developed "Power-Over-Skin," a technology enabling electricity to travel through the body to power wearables, potentially eliminating the need for traditional batteries. The system uses a single battery-powered transmitter worn on the body to power multiple receivers. Tests successfully powered small objects like LED lights and a Bluetooth joystick ring. Researchers aim to increase power output to potentially power more energy-intensive devices like smart glasses and earbuds in the future.
