OLED Fold Phone

The possible future of mobile phone technology, Kyocera recently unveiled a kinetic energy phone that is capable of folding up like a wallet. Designed by industrial designer Susan McKinney, the EOS phone consists of a soft, semi-rigid polymer skin and a flexible low-energy OLED screen. Shape memory allows the phone’s keys to pop up when in use and blend in with the surface when not in use.

The more you use the phone, the more kinetic energy is turned into an electric charge through an loads of tiny piezoelectric generators. I haven't a clue what those are!
