RUNNING out of battery and charging your smartphone every night could soon be a thing of the past.
Brit scientists have developed a pioneering ‘smart glass’ material to replace the screens on phones, smartwatches and tablets which uses no power.
The discovery is significant as illuminating the display on a device currently drains around 90 per cent of its battery.
Oxford University engineer Dr Peiman Hosseini, 32, told a
Sunday newspaper: “You have to charge smartwatches every night.
But if you had a smartwatch or smart glass that didn’t need much power, you could recharge it just once a week.”
With the growing popularity of smartwatches, gadget firms are desperate to solve the age-old problem of limited battery life.
