The Sticker Phone concept is designed by Liu Hsiang-Ling. Since most of us place our phone near windows for better signal reception, Liu put on a solar panel to the back of the phone and giving it a slight arch so that it can stick (via suction) to the window glass to absorb sunshine for power. The Sticker phone is made with polysiloxane (silicone) and can be made feasible. More pictures after the jump.
