FINNISH PHONE MAKER Nokia has registered a patent application to power batteries through piezoelectric kinetic energy.
Nokia has sensibly called its device, designed to harvest piezoelectric kinetic energy, a piezoelectric kinetic energy harvester. The patent application filed at the US Patent and Trademark Office shows that Nokia wants to harness the kinetic energy generated by movements caused to mobile hardware carrying the batteries:
It reads, "In a device according to at least some embodiments, kinetic energy resulting from acceleration of a battery powered device is harvested using piezoelectric elements that are positioned to receive forces along multiple different axes."
Kinetic energy powered watches have been around for a long time. But Nokia is going a step further by trying to harvest every movement that the batteries are subject to. Nokia intends to do this using a force-transferring assembly:
"So as to increase the amount of forces on those piezoelectric elements, the mass inducing such forces is increased by locating heavier device components within an assembly that transfers forces to the piezoelectric elements in response to device translation and/or rotation." µ
