Designers have devised a device that gathers perspiration from the tip of your finger to generate electricity
Designers have devised a device that gathers perspiration from the tip of your finger to generate electricity, and it requires no effort on your part. To be honest, it can work as you watch or even sleep.
The flexible, thin strip, which folds over the tip of a finger like a Band-Aid, turns synthetic chemicals found in human sweat into small amounts of electrical energy. Fingers sweat constantly, allowing the device to function without the wearer having to move.
“This technology provides a net gain in energy with no effort from the user by using sweat on the fingertip — which flows out naturally regardless of where you are or what you’re doing,” said Joseph Wang, a professor of nanoengineering at UC San Diego and co-creator of a paper depicting the item, published Tuesday in the journal Joule.
