Quantum trick for pressure-sensitive mobile devices – BBC News

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”.

Besides control for scrolling, the pressure-sensitivity could lead to a “third dimension” in touchscreens. For instance, instead of many “2-D” pages of applications, they could be grouped by type on a single page – using the press of a finger to dive into each type and select the desired app.
