'Flexible' phones to banish breakages
Costly smartphone screen breakages could soon be a thing of the past after British scientists invented a cheap flexible touchscreen made of silver and graphene.
Current screens are so brittle because they are made of indium tin oxide and covered with glass.
Not only is indium tin oxide fragile, it is also difficult to extract from the ground, making touchscreens expensive to repair.
Scientists at the University of Sussex combined graphene - made from a layer of carbon atoms - with silver nanowires, to create a film matching the performance of regular screens, but at a fraction of the cost.
The material is also super flexible, meaning the top layer of the screen could be made of something far more bendy and less breakable.
Dr Matthew Large, lead researcher, said: "This paves the way towards one day developing completely flexible devices."
