Carnegie Mellon University has developed a breakthrough technology called Power-Over-Skin, which can transmit electric current through human skin to power various wearable devices. This technology is expected to completely change the way wearable devices are powered, getting rid of the constraints of batteries and achieving truly wireless power supply. This innovative technology is currently in its early stages, and researchers have successfully used it to power low-power electronic products such as LED earrings. In the future, it is expected to be used in medical devices such as blood glucose monitors and pacemakers, as well as smart glasses, Consumer wearable devices such as fitness trackers.

This technology is expected to revolutionize the way wearable devices are powered, making battery-free devices a reality. The researchers noted that the technology is still in its "early stages." Currently, they are demonstrating technology that supports low-power electronics, such as the LED earrings pictured above.
"It's similar to how radios use air as the medium between the transmitting station and the car stereo," said Andy Kong, a researcher at Carnegie Mellon University who said they are using body tissue as a transmission medium to transfer energy to these devices.
The emergence of Power-Over-Skin technology heralds a new direction for the future development of wearable devices. This technology will not only simplify device design and extend service life, but more importantly, it will revolutionize medical care and personal health monitoring. Although this technology is still in the research and development stage, its broad application prospects are already exciting.
