Boffins come up with self-repairing smartphone screens

A team of researchers has come up with a new material that could pave the way for self-repairing smartphones, robots and other electronic devices.

The boffins from the American Chemical Society claim that the material, which can stretch up to 50 times its usual size, is able to heal itself “like nothing has happened” even when cut in two.

The material is flexible, transparent and is similar to human skin. When exposed to electrical signals, a current is generated that creates a chemical bonding reaction between molecules.

The most obvious applications for electronics devices seem to be self-healing displays, although lead researcher Dr Chao Wang is also exploring the possibility of a self-healing lithium-ion battery.

The technology is similar to the hydrogen-infused rear cover found on the LG G Flex, which allows for small scratches to be healed. However this material can “automatically stitch itself back together” within one day of being sliced into pieces. The team will present its research at a Tuesday meeting of the American Chemical Society.
