The device can easily fold up to look something like a wallet. Its industrial designer is Susan McKinney.
The futuristic phone is made of soft, semi-rigid polymer skin that covers a flexible OLED display. Incorporating a shape memory, makes it possible for keys to pop-up from the device's surface when it's unfolded and fade away when it's not used.
Kyocera's EOS phone has a compact shape when folded and you can make simple phone calls, but when unfolded, the phone unveils a pretty large screen. The device feeds off its energy from physical interaction.
It transforms kinetic energy into an electric charge through an array of small nano-scale-piezoelectric generators. Thus the more you interact with the gadget the more energy it generates and the less battery power it requires.
Currently EOS concept phone is just in designing stage, but the company's staff in San Diego and Bangalore is studying different ways of integrating some of the phone's concept ideas in the devices that will be produced in the near future.
