Scientists have developed a ‘self-healing’ material that could be ready to fix broken smartphone screens within the next three years. Duncan Wass and his team at the University of Bristol patented a carbon-based healing agent that, when a crack appears on a surface, exudes a liquid to fill up the gap. Wass’s novel invention could be also used to ‘self-repair’ damaged aeroplane wings in mid-flight. Metro spoke to Wass on his revolutionizing product and how he was inspired by the way the human body ‘self-heals’.
Q: A ‘self-healing’ carbon material – sounds very sci-fi. Where did you get the idea for it?
