Nokia is testing a revolutionary phone concept that is not based on the looks, design and features but on battery life and, especially, recharging. Research is under way to create the world’s first self charging phone.

The principle on which the handset may function is rather simplistic. The phone is capable of converting kinetic energy into electricity. Following a technique named “Piezoelectric Kinetic Energy Harvester”, every time a user is shaking the phone, it will generate electricity, thus recharging the handset.

The generator uses piezoelectric crystals which respond to pressure or phisical force by generating a small electrical charge, informs PocketPicks. The same is used for wristwatches, however, Nokia’s intervention may result in the first practical method of generating enough energy to power a smartphone.

According to PocketPicks, the phone’s battery “will be suspended on weightened inner frame that allows slight movement against the piezoelectric material”, meaning that if the user just carries the handset in the pocket, it will generate enough power to make the device completely usable.

At the moment, however, the entire project is at the planning stages and there is no assurance that Nokia will release a self-charging handset in the near future.
