A new research paper from Carnegie Mellon University could have the answer: scientists have developed a technique to power the next generation of wearable tech via skin contact.

Researchers at Future Interfaces Group have found a way to deliver power to wearable devices through the human body. The method is called Power-over-Skin, and it could be the gateway to a future where the best smartwatches no longer need a built-in battery.
