Technology has been advancing day by day and one such instance we can witness is research which was conducted by UC San Diego Jacobs School of Engineering, as they have developed an extremely thin and flexible wearable strip that can stick to your fingertip and generate small amounts of electricity.

And astonishingly, it can be used as a source of power for small electronics.

As per the sources, the electricity is generated when your finger sweats and can be worn even when sleeping. The device can also generate extra power when you press on it. So you can continue typing on your computer, texting, or even play the piano.

Lu Yin, a nanoengineering PhD student said, “Unlike other sweat-powered wearables, this one requires no exercise, no physical input from the wearer to be useful. This work is a step forward to making wearables more practical, convenient and accessible for the everyday person.”
