SCS Researchers Develop Method To Transmit Power Through the Body #WearableWednesday

Researchers at Carnegie Mellon are trying to “free wearables.” The devices aren’t battery free so much as the battery doesn’t need to be connected, with wires. That’s because the current flows through the wearers skin! Via Carnegie Mellon School of Computer Science:

Still in its early stages, Power-Over-Skin allows researchers to design and implement new methods of transmitting power frequencies through the human body. In the study, researchers powered small objects like LED lights, but they envision powering smart glasses or other wearables in the future.

…The CMU researchers used a single battery-powered transmitter that’s worn on the body to send power to receivers — objects like a Bluetooth joystick embedded into a ring and a light-up earring. While study participants wore these devices in locations ranging from the wrist to the ankle, researchers noted a correlation between the power the devices received and their distance from the transmitter. The closer the transmitter, the more power a receiver got.
