In addition to adding pressure sensitivity to screens, the company claims that the technology, called Quantum Tunneling Composite (QTC) Clear, could make touch screens thinner, more rugged, and more energy-efficient.
Peratech aims to bridge the gap between the two main touch-screen technologies: capacitive and resistive, says joint CEO Philip Taysom. Capacitive touch screens are found in mobile phones and tablets. They respond quickly to multiple fingers at a time, but rely on a grid of electrodes that constantly draw power when a screen is switched on; the bigger the screen, the more power the capacitive sensors gobble up.

A British firm named Peratech is developing a new type of touchscreen that using a clear composite material that bridges the gap between resistive and capacitive touchscreens. The company's Quantum Tunneling Composite (QTC) Clear could make touchscreens thinner, more rugged, and more energy-efficient, while also being able to register pressure. The first product based on QTC Clear is expected to be available by year-end. More details at MIT Technology Review.
