Chemistry

Self-Healing Polymers for Flexible Electronic Skin Applications

Quick fact

Some self-healing polymers can recover up to 100% of their original mechanical strength and electrical conductivity after being completely severed, thanks to reversible chemical bonds that reform on their own.

Why this is interesting

Imagine your phone screen repairing its own crack overnight, or a robotic fingertip that heals after a cut. How can a material that is meant to conduct electricity also be able to knit itself back together?
