Self-healing surfaces are theoretically the perfect solutions to easily worn-out gadgets, but our dreams come crashing down as soon as deliberate contact is involved; as existing materials don't conduct electricity, they can't be used in capacitive touchscreens and other very logical places. If Stanford University's research into a new plastic polymer bears fruit, though, our scratched-up phones and tablets are more likely to become distant memories. The material can heal within minutes of cuts through fast-forming hydrogen bonds, rivaling some of its peers, but also includes nanoscopic nickel particles that keep a current flowing and even respond to flexing or pressure.
