Automatically charge your electronic gadgets for free while on move

Hand-held mobile computing devices are getting more advanced each year. With this, their power requirements have also grown considerably.

Even high-end power-banks and heavy-duty batteries are not able to fulfill the power requirements of many mobile computing devices.

Recently, Purdue Research filed a patent that reveals an energy harvester, which converts kinetic energy into electrical energy to power electronic devices.

The energy harvester includes an inner ring-shaped cylindrical levitating magnet that sits inside a larger fixed ring magnet. Further, the harvester includes levitating coils that are arranged such that any relative movement between the levitating magnet and the ring magnet induces voltages in the levitating coils.

The energy harvester can produce electric current by converting the vibrations from a machine, a building, or even human movement. This technology could be a game changer for the wearable devices industry.
