British scientists have created a material that replaces the screen glass for phones, tablets and smartwatches, but uses no power – meaning they could be charged weekly.

Technology firms have focused on improving battery life. But the British experts say tackling the main drain on a gadget’s power may give better results.
Oxford University engineer Dr Peiman Hosseini, who invented the material, told the Sunday Telegraph: ‘You have to charge smartwatches every night. But if you had smart glass, you could recharge it just once a week.’
