Nokia Developing Self-Charging Phone

Nokia is developing a phone that harvests its own energy through a combination of kinetic and piezoelectric technologies. With a patent secured last week, Nokia’s envisions a phone that can either charge itself or at least temper the energy costs, particularly useful in less-developed countries where access to energy for mobile devices is limited.

New Scientist explains below:

Strips of piezoelectric crystals sit at the end of each rail and generate a current when compressed by the frame. So as the user walks, or otherwise moves the phone, the motion generates electricity. This charges a capacitor which in turn trickles charge into the battery, keeping it topped up.
