Self Charging Phones from Nokia - Never needs to be charged!!

Now Nokia made it possible to charge a cell phone without needing a plug-in point to connect your charger. Nokia people have come with a cellphone that can recharge its own battery by harvesting energy from the user's motion - they called it as self charging.
Microsoft had already launched wireless smart charger which i had posted early but it is working with the induction method; and it needs electricty to work, but Nokia is looking forward with a new technology. Nokia R&D started experiments a long while, their technology is based on converting movements into electricity.

Nokia envisages a phone in which the heavier components such as the radio transmitter circuit and battery, are supported on a sturdy frame. Strips of piezoelectric crystals sit at the end of each rail and generates electricty when compressed by the frame such that motion, by the user or the movement of the phone, generates electricity. That in turn charged a capacitor and subsequently the battery, boosting the charge.
