Ever heard of quantum tunneling? It's the basis for the latest approach to gather steam in the never-ending quest to endue touchscreens with force recognition, and its promises are as lofty as you'd expect. Developed by UK researchers Peratech, this new methodology revolves around a 75-micrometer (less than a hundredth of a milimeter) quantum tunneling composite, which display makers can add to their screens relatively cheaply and painlessly. The pressure-sensing layer consumes no power when it isn't depressed and requires a miniscule two micrometers of movement to register a touch. Japanese display maker Nissha (who counts
