Peratech is a small company progressing a unique and patented piece of science which is proving to have high commercial value. ‘Quantum Tunnel Composites’ (QTCs) are pressuresensitive materials that are capable of increasing the functionality of many types of touch sensitive device, ranging from textile switches to touch-pads and touch-screens (one version of the material is an extremely sensitive substance with a resistance range of more than one trillion ohms under fingertip pressures). The use of QTC can significantly reduce the component count in such devices, and hence their build-costs. Peratech develops and makes bespoke forms of QTCs to meet customers’ requirements and then sells licences for their use. The company holds the worldwide patents for QTCs and is the only supplier. One form of QTC is a screen printing ink which allows the active component of unique types of switches, keypads, sensors and touch-screens to be printed. However, at the moment not all factors affecting the performance of the material in ink form are understood. Additionally, there are many devices where the ability to use other types of printing (e.g. flexography, lithography etc.) would open up even more applications. This project concerns the use of Peratech’s innovative Quantum Tunnelling (QT) Ink in the manufacture of touch screens. The project will develop a range of inks based upon this material, enabling Peratech to introduce the x-y-z touch responsiveness of their QT ink to a far wider range of markets. In addition, the project work will increase the understanding of the properties of QTC ink systems and hence improve their application technology and robustness. The work will be carried out by Peratech and a subcontractor: the PETEC facility of the Centre for Process Innovation, part of the High Value Manufacturing Technology Innovation Centre.

British firm Peratech today unveiled a new transparent version of its quantum tunnelling composite (QTC) material, which the company claims could replace current touchscreen technology used in smartphones and tablets. The technology – proposed last year for smartphones and switches – has now grown up to create tablet-sized touchscreens. These will use less power than alternatives, and will allow better interaction, since they can respond to how hard a user presses, as well as to where their finger is. QTC technology works by quantum tunnelling between conductive nano-particles, embedded in an insulating elastomeric binder. When pressure is put on the material, the nano-particles – which are spikey like medieval maces – get closer together, allowing electrons to ‘tunnel’ between them. This turns the pressure into an electrical signal. The technology can be used to create force-sensitive touchscreens that conduct better when they are pressed harder. For example, a user could increase the speed of scrolling through a list of contacts by exerting more pressure on the screen. Peratech claims that QTC could completely replace current resistive touchscreen technologies, and also enhance capacitive ones. “Both resistive and capacitive touchscreen technologies have their drawbacks,” explained Philip Taysom, Peratech’s joint CEO. “Resistive is not very accurate and can’t do multi-touch so it is becoming less popular than capacitive, but the latter uses a lot of power, constraining it to smaller screen sizes. “Our new, QTC Clear touchscreen design offers the best of both technologies without their drawbacks. It can be made in any size and provides multi-touch, high sensitivity with great accuracy, ultra low power consumption and additional intuitive features with the third dimension of pressure to more easily manipulate and control information on the screen.” When built into touchscreens, QTC acts like the jam in a jam sandwich – where the butter is a thin layer of Indium Tin Oxide (ITO) and the bread is the glass. The QTC Clear layer is only 6-8 microns thick. Peratech has been building its QTC into touchscreen devices for over a year, but the new QTC Clear technology will help to improve accuracy, because the ‘jam’ covers the whole screen rather than just the edges (or the ‘crusts’) of the device. This not only makes the device more sensitive to touch commands – because it is able to sense exactly where the pressure is being exerted rather than approximating – but also enables multi-touch. Unlike capacitive touchscreens, which use a lot of energy because they have a current running through them constantly, QTC draws virtually no current unless a force is applied. This means it is suitable for much larger screens. The company claims that capacitive touchscreen manufacturers that build QTC Clear into their devices will be able to provide additional features from the force sensitivity, such as 3D menus, variable line widths, and more intuitive gaming interaction. They can also reduce the power use of the screens, by using the QTC Clear screen to selectively activate parts of the capacitive matrix, eliminating the need for a constant current. “This is a very interesting new technology that could revolutionise the whole touchscreen industry from automotive to computers,” said Paul O’Donovan, principal analyst at Gartner’s semiconductor division. The news follows a report last month that a Cambridge University-backed company has developed an acoustic processing technology, in the form of a software-only upgrade, that could one day offer another alternative to the touchscreens currently used in smartphones and other devices. The technology, called TouchDevice relies on the acoustic signal produced by the user swiping or tapping on the display to effectively simulate a touchscreen. The technology isn’t limited to the display screen, as users can tap or swipe on the entirety of the handset case, the company said. Touchscreens have increased dramatically in popularity over the last year, thanks largely to the success of Apple’s iPhone and iPad, which use capacitive touchscreen displays. There are just over 20 million tablets in use today, with a market potential of over 180 million sales by 2014, according to RBC. “People are so much more comfortable now,”  said Mike Stinson, Motion’s vice president of marketing, speaking to eWEEK Europe in January. “Touching the display has become acceptable.”

The idea of a 3-D tablet or touchscreen is great, except that current hardware limits us to exploring that three-dimensional world in two dimensions. Peratech’s QTC (“Quantum Tunnelling Composite”) Clear is a force-sensitive touchscreen that would change that. Philip Taysom, Peratech’s Joint CEO, says that the third dimension of pressure will let users “more easily manipulate and control information on the screen.” That means artists could better create digital masterpieces on touchscreens, musicians could play their iPad tunes with greater finesse, and gamers could have additional actions and controls in their favorite titles. Applying varied levels of force could determine how deep you penetrate through a 3-D user interface. QTC Clear (sandwiched between glass plates) could entirely replace a resistive touchscreen, or be used to enhance a capacitive one. It’s 6-8 microns thick, and can sense multitouch gestures and pressure changes of only a few microns. Almost no current is drawn by the screen when it’s not in use, making it less of a battery-hog than the capacitive touchscreens we’re using in devices now. Previously, QTC technology was opaque, so its applications were limited. But QTC Clear, which, like its name suggests, is transparent, already has its footing in the industry: It’s already been licensed to an undisclosed “leading touch screen manufacturer.” I can see the iPad 3 rumors lining up now.
