Nokia files patent for piezoelectric powered cell phone battery
The Finnish giant has filed a patent for a “Piezoelectric Kinetic Energy Harvester” – which is actually a cell phone battery that’s “contained within a first frame that is coupled to a second frame by one or more piezoelectric elements.”
Said battery should be included into a phone with the help of other piezoelectric elements. A power controller would gather electrical energy resulted from the phone’s everyday use (rotation, “acceleration in numerous directions” etc) – and Nokia plans to use this energy “to at least partially recharge the device battery”.
Of course, this is just a patent application for now, and it might take quite a few years until we’ll see a Nokia phone that actually users piezoelectricity and kinetic energy.
It would be really nice if Nokia manages to make a phone that doesn’t need a standard battery (like the one seen above) at all, and can run only with the kinetic energy resulted in the way described in the patent application – which can be seen here.
