Nokia has applied for a patent for a technology that would allow future cell phones to charge themselves up - without the need for a power socket.
This invention is based on the ability of the charger to convert kinetic energy into electrical energy, and thus, this charger will benefit from the human movement and converts this movement into electrical energy which can recharge cell phone self.
The new charge includes two separate frames rubbing against one another within the phone. The smaller case would contain a battery that would store the charge generated from the movement of the piezoelectric elements. This structure would possible increase the size of the device, not to mention the possibility of feeling constant movement of loose panels inside the appliance housing.
