Though we saw another paper phone not to long ago, but the latest paper phone we’re seeing is much more high tech. Like the Kindle, it uses an E-Ink display and works by bending the phone into different positions to make calls, use apps, and listen to music.
Created by research teams at Queen’s University in Canada and Arizona State University, the 9.5-centimeter (diagonal) screen is actually a lightweight flexible display. It’s said to feel similar to a bendable piece of plastic.
Its thin body resembles that of a paper document, but, according to the video below, underneath the screen is a “flexible printed circuit with resistive bend circuits,” which are used to identify the bending of the display screen. The user actually chooses the shape for each function. For example, you can choose to bend the upper-right corner to make a call, or bend the lower left to listen to music. These shapes are then recorded into the software, and when repeated, they send the appropriate action to the device.
