According to a patent published Aug. 16, Motorola is working on self-healing phone screens. The idea is to use what is called “shape memory polymer” over an LCD or LED screen that uses thermal cycling (rapidly altering the temperature) to recover its original shape after becoming altered. The phone would be able to detect cracks in its screen and then begin to heal it simply by applying heat. Additionally users would be able to help the process along with their own body heat.

Unfortunately the polymer doesn’t have the same smooth appearance as a glass screen, which may deter some users. However, this tech would be ideal for users who have trouble keeping their screen intact. And a capacitive touch sensor can also be layered in, so it would work with touchscreen phones too.
