Self-charging cellphone battery is a Nokia patenting
Posted By admin on March 9, 2010
Cellphone giant Nokia has filed for a patent in the US for a self-charging cellphone battery. Officially dubbed Piezoelectric Kinetic Energy Harvester, the idea involves a battery that’s mounted in a larger frame and isolated from it by piezoelectric elements. Thus, kinetic energy is used to produce electricity to “at least partially recharge the device battery.”
Phones themselves could have integrated piezoelectric elements to provide further energy for the dell battery . The idea is similar in theory, if not execution, to kinetic powered watches, which use motion to charge their batteries GK479 , FK890 , Inspiron 1720 battery . According to the Nokia patent, larger components inside the phone, such as the radio transmitter and battery travel along two sets of rails, one that travels horizontally and one that travels vertically, before hitting a capacitor that charges the battery
