Quick show of hands: how many of you have a scratch or crack on the screen of your smartphone?
There’s only three options for what to do when that happens, isn’t there? Live with it, if it’s not too big or not affecting your phone’s performance too much; get it replaced, if it can be; or replace the phone completely. Makes you wonder why more of those screens aren’t created to handle a drop now and then.
Well, another option looks to be right around the corner – self-healing screens. Chemists at the University of California at Riverside have developed an incredible material that has the ability to heal itself from cuts and scratches. They even tore the super-stretchy material apart and it still stitched itself back together in under 24 hours! While a similar material is already used on the back covers of some smartphones, this is the first electrically conductive self-healing material to be created, a necessity for touch screens. And the best news is that the chemist leading the research, Chao Wang, predicts that this new material will start being used in both smartphone screens and batteries by 2020!
