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.
