We have seen some incredible breakthroughs in technology lately but one issue that still needs to be solved is that of battery trouble. No matter how fancy a gadget gets, it is almost always limited by its battery life. The next big thing the world of tech requires is never-ending batteries, and looks like MIT is paying attention.

A group of researchers at the university are working on self-charging batteries, which in turn means never-ending battery life. The idea is to produce electrical energy out of the mechanical energy of locomotion. The mechanical energy produced as a result of walking can be used to charge electronic devices.

The procedure involves two thin [...]
