Since Wednesday, Motorola filed a new patent for a smartphone screen that can “heal” after it was cracked. Those screens would be made from a “shape memory polymer”.
We are not talking about a healing treatment in a shop or done by workers but by the phone itself. After the screen is cracked in the phone, you can open an app or press the repair button. Some processors will be turned on by this and will heat up the screen. This is the stimulus it needs to be healed. There can be other stimuli as well but heat is the most common.
The patent tells us that: “Shape memory polymers are stimuli-responsive materials in that a corrective response can be applied as a result to a stimulus,"
If we talk about scratches or dents it can be healed fully and fractures can be healed for the most part.
Not only smartphones would be the application. In aircraft and the spaceship industry this material could become of great use. It is important to notify that even when they have the patent now, they will not produce it soon. But it shows that smartphone makers are constantly searching after new and better materials.
