Non-critical touchscreens using graphene

Professor Alan Dalton and his team have developed a new way to make smartphone touch screens that are cheaper, less brittle, and more environmentally friendly. The breakthrough from physicists at the University of Sussex has been to combine silver nanowires with graphene – a two-dimensional carbon material. The new hybrid material matches the performance of the existing technologies that use indium tin oxide, which is currently used to make smartphone screens, is brittle and expensive. The primary constituent, indium, is also a rare metal and is ecologically damaging to extract.
