An unbreakable mobile phone screen

British scientists have developed an unbreakable touchscreen for smartphones, potentially saving users thousands of pounds in repairs each year.
And at a fifth of the cost of current touchscreens, the new technology – which could be rolled out on mobiles as early as 2018 – could send the prices of phones, TVs and tablets tumbling.
Currently electrodes (electrical conductors) in touchscreens are made from indium tin oxide (ITO), a rare and expensive metal.
