Researchers have developed a transparent smartphone screen material that can repair its own scratches.
The material shares many properties with human skin. It is flexible and transparent, and can be stretched up to 50-times its usual size.
When exposed to an electric current, a chemical bonding reaction is created between molecules – allowing the material to heal itself.
Researchers said the material has potential uses in smartphone manufacturing, allowing devices to automatically repair screen scratches or heal cracks.
“A self-healing material, when carved into two parts, can go back together like nothing has happened, just like our human skin,” said researcher Chao Wang.
The research will be presented at a meeting of the American Chemical Society this week.
