Click and recharge: scientists have invented a new source of energy

Engineers from the University of California have created a device that converts the touch of a finger into a source of energy.

The device is a thin flexible tape that is worn on the fingertip. It is able to produce energy even when the user is sleeping or sitting quietly – the device gets most of the energy from sweat, which is formed on the fingertips. Typing, correspondence, and playing the piano can also be a source of energy.

About 400 MJ of energy accumulates in 10 hours of sleep. This will be enough to power the smartwatch for 24 hours. And in one hour of typing and clicking the mouse accumulated about 30 mJ. Ideal for travel or for a walk. The chip still looks scary, but the idea is cool. Would you wear such a device?
