It is now possible to charge a cell phone without needing a plug-in point to connect your charger.
This is made possible by Nokia. It created a cell phone which is capable of recharging its battery as it can draw energy from the movements and the motion of the one using it!!
This self-charging cell phone can function with heavier machinery supported with a powerful frame like the radio transmitter circuit and battery.This frame is equipped with "rail mechanism" and it permits moving of the set side wise as well as horizontally up and down.The rails, towards the end have strips of piezoelectric crystals which when compressed by the frame helps to produce electricity by phone's or the user's movement.
The energy thus produced is stored for further use in a capacitor.
