The new concept phone design from Kyocera makes solar phones look archaic. The EOS phone is a flexible, folding phone with a large OLED display. Even more interesting is that the phone is powered by kinetic energy.
When being used for calls, the phone remains folded up like a small wallet, but it can unfold to reveal the OLED screen and QWERTY keyboard. The flexibility is achieved through using a soft, semi-rigid polymer skin. The keyboard itself is flexible and has shape memory so that the keys pop up for use, but blend into the surface when not being used.
The coolest feature is that using the phone also powers it. Small piezoelectric generators derive an electric charge from its use. The more you fiddle with the phone, the more energy is generated.
This phone is still in the early design stages, but features of this phone could end up in upcoming versions of Kyocera phones. Continue reading for Kyocera's full description of the EOS.
