Scientists Created the World's Toughest Self-Healing Material, and It Repairs Screens in a Second. - Interesting Engineering

You are not alone, and the researchers at the Indian Institute of Science Education and Research (IISER), Kolkata might have just found the perfect material to make a smartphone screen: A transparent material that is hard and self-heals when cracked.

The researchers used a piezoelectric organic material, which converts mechanical energy to electrical energy and vice versa, to make needle-shaped crystals that aren't more than 2 mm long or 0.2 mm wide, according to the experimental results which were published in the journal Science.

“I can imagine applications for an everyday device,” said Bhanu Bhushan Khatua, a member of the team from IIT Kharagpur." Such materials could be used for mobile phone screens that will repair themselves if they fall and develop cracks.".
