The soft cells are made of hydrogel and salt, and they form the first potentially biocompatible artificial electric device that generates more than 100 volts. It generates a steady buzz of electricity at high voltage but low current, a bit like an extremely low-volume but high-pressure jet of water.
While the technology is preliminary, the researchers believe it may one day be useful for powering implantable or wearable devices without the toxicity, bulk or frequent recharging that come with batteries. Further down the road, it could even lead to bioelectric systems that could generate electricity from naturally occurring processes inside the body.
This project is led by Max Shtein, a professor of materials science and Engineering at the University of Michigan.
