Nokia Phones to Recharge Automatically, Soon!

Soon, your Nokia cell phone will never run out of battery, while you are on the go.
New Scientist figured out that Nokia has filed for a US Patent for a phone that recharges as the phone user moves.
Some watches already use similar pattern for generating energy – they use circular frames on back end of dial, that keeps moving to generate energy.
Nokia thinks that there can a phone in which the heavier components, such as the radio transmitter circuit and battery, are supported on a sturdy frame. This frame can move along two sets of rails, one allows it travel up and down, the other side to side.
Strips of piezoelectric crystals sit at the end of each rail and generate a current when compressed by the frame. So as the user walks, or otherwise moves the phone, the motion generates electricity. This charges a capacitor which in turn trickles charge into the battery, keeping it topped up.
