An electronic ink that can be printed on a laser and then conducts electricity has been developed by scientists.

The graphene-based ink was used to make a small plastic keyboard by researchers at the University of Cambridge, who found the one atom-thick material could be used to make cheap, printed electronics.

It could be used in the future for people who need heart monitors, as they could be embed onto clothes, or for tracking luggage in an airport to ensure it is loaded on to the correct plane.

The graphene-based ink has a number of interesting properties, including flexibility, optical transparency, and electrical conductivity.
