Could tomorrow's smartphone screens be self-healing?

In the future, there may be no need to replace your cell phone's cracked screen, as it might be able to repair itself. — Relaxnews

Researchers in Canada are currently working on developing self-healing polymers for cell phone screens. The aim is to automatically heal scratches or cracks, in turn increasing the lifespan of smartphones.

The team of researchers at Concordia University in Montreal, Canada, led by doctoral student Twinkal Patel, has developed self-healing polymer networks that are already producing good results at room temperature, which is a real challenge.
