University of Melbourne researchers are probably going to save a lot of people a lot of money, by developing a self healing gel that could prevent phone screens from permanent damage.

Melbourne School of Engineering researcher Dr Luke Connal said:

After printing, these objects can heal a crack or even a cut and regain their original strength. This could enable custom printing of coatings that can heal after breakages, potentially as coatings for mobile phones.

The materials we developed can also change shape when triggered by being swollen in a solvent, such as water. This enables printed objects to change shape once printed, which is known as 4D printing.
