Nokia planned to develop self-charging mobile phones by harvesting piezoelectric kinetic energy from the movement of the phones. To protect its technology from being stolen, Nokia had filed a patent application with the U.S. Patent and Trademark Office back in 2008. The patent application may be viewed here. In the past few years, we had seen solar-powered mobile phones, such as Samsung Blue Earth, with little success. Nokia’s new self-charging technology through movement, and Toshiba’s fuel cells technology might be the answer for energy-hungry smartphones.
