Cellular phone giant Nokia has filed for a patent �for a self-regenerating phone battery, or in their own words, a “piezoelectric kinetic energy harvester”. �The patent essentially involves a battery that�s �contained within a first frame that is coupled to a second frame by one or more piezoelectric elements.�
Similar to the�concept�of kinetic powered watches, which use motion to charge their batteries, Nokia’s technology proposes generating energy by kinetic movement. �Nokia plans to use this energy �to at least partially recharge the device battery�.
Nokia envisions a phone in which its heavier components, say, the battery and radio transmitter circuits, travel along a pair of rails perpendicular to one another, and finally coming into contact with the�capacitor, which charges the battery.
