Nokia has filed a patent with the US patents office for a cell phone that re-charges it self. The phone will convert energy from the owner's motion top charge itself. The phone's radio transmitter circuit and battery will sit on a sturdy frame. The frame can move along sides and in up and down direction with the help of rails fitted inside the phone. The rails will have piezoelectric crystals that would generate current when compressed and the motion generates electricity. Indeed a very innovative patent from Nokia but need to see in how much time this phone reaches the market. If it does, I am sure its going to cost a bomb..at least during its initial period of launch.

Abstract from US Patent Site - "A battery for an electronic device is contained within a first frame that is coupled to a second frame by one or more piezoelectric elements. The second frame is coupled to a device chassis by one or more additional piezoelectric elements. In response to translation and/or rotation of the electronic device, portions of forces induced by the battery mass are transferred to the piezoelectric elements. Electrical energy output by these piezoelectric elements is received in a power controller and can be applied to the battery. Additional device components can also be contained within the first frame so as to increase the total mass that induces forces applied to the piezoelectric elements."
