Nokia, the mobile phone maker has developed a self-charging phone. The devise is designed to use the kinetic energy created when a person moves around. The patent application was filed with the USPTO. The new device could power a phone; however this technology could be used in any portable electronic device like a music player, medical equipment or games console etc., leading to a world devoid of batteries and chargers altogether.
The proposed machine would use piezoelectric crystals which create an electric current when bent or compressed. In Nokia’s design the radio aerial and battery, the phone’s heavier machinery are supported on a strong frame that can move alongside two sets of rails. Strips of piezoelectric crystals at the end of each rail would create an electric current when hit and compressed by the frame. So a person would create electricity when he gets up or walks or moves the phone and this energy would charge up a capacitor that would charge up a battery.
Such a self-charging mobile would indeed be a great asset for this electricity-dependent world.
