Kyocera’s new EOS folding concept phone has a cool flexible OLED screen, changing its form factor from a clamshell into something like wallet or clutch-purse. There is a soft, semi-rigid polymer skin surrounds a flexible OLED display. Not like solar charged cellphones from LG or Samsung, this phone does not need a battery…. -:)
The device feeds off of our physical interaction with it, translating kinetic energy into an electric charge via an array of nano-scale piezoelectric generators. The more we interact with Eos, the more energy it creates – without using batteries.
