The study was published in Science by a team of researchers led by Professor Takuzo Aida from the University of Tokyo. Titled "Mechanically robust, readily repairable polymers via tailored noncovalent cross-linking," the research promises a unique hard glass-like polymer called "polyether-thioureas" that can heal itself with only hand pressure. This makes it different than other materials that need high heat to heal up from a break.

"High mechanical robustness and healing ability tend to be mutually exclusive," said researchers. "In most cases, heating to high temperatures, on the order of 120 degrees Celsius or more, to reorganize their cross-linked networks is necessary for the fractured portions to repair."

According to The Guardian, the special glass polymer was discovered by mistake by a graduate student, Yu Yanagisawa, who thought the material would become a type of glue. He found that cut edges of the polymer would stick to each other, and formed a strong sheet after being compressed by hand at 21 degrees Celsius. This isn't the first time we've seen self-repairing phone tech, of course, with screen protectors that heal themselves and a Motorola patent for a self-repairing screen. However, new breakthroughs like this may help make broken screens and costly repairs a thing of the past.
