Nokia wants patent on self-regenerating phone batteries, piezoelectrics and much magic involved

In Nokia's own words, what we're looking at is a "piezoelectric kinetic energy harvester." Working along the same principles as kinetic wristwatches have done for a long time already, Nokia's idea is to capture the energy generated by the phone's movements and to refashion it into beautiful, clean-as-a-whistle electric power. By allowing the heavier internal components to move on rails within the phone as part of a "force-transferring assembly," the Espoo think tank has figured out a way to capitalize on all the small forces of acceleration and rotation that we subject our phones to on a daily basis. It would seem overly ambitious to expect this to replace the trusty old charger, but we give credit to Nokia for even thinking about it. Check out some schematics of how this would work after the break.
