No, this is not some new device. It’s just a plain, old, graphite pencil, being used in a new way.
"By drawing a rectangle on a piece of paper with an ordinary pencil, researchers in China have made a strong, highly sensitive sensor that can measure how much it bends.
“The graphite rectangle drawn on the paper conducts electricity, but has quite a high resistance. As it bends, the resistance either increases or decreases, depending on which way it is distorted. By measuring that resistance, the precise angle of bend can be detected.”
