Quantum Trick for Pressure-Sensitive Mobile Devices

Hand-held devices could soon have pressure-sensitive touch-screens and keys, thanks to a UK firm’s material that exploits a quantum physics trick. The technology allows, for example, scrolling down a long list or webpage faster as more pressure is applied. A division of Samsung that distributes mobile phone components to several handset manufacturers has now licensed the Quantum Tunnelling Composite. The approach could find use in devices from phones to games to GPS handsets
