Pressure Sensitive Touchscreens to Hit Phones

Peratech QTC
Peratech already caught everyone’s attention a few weeks ago when it announced its pressure-sensitive touchscreen technology. We were excited about the promise of quantum tunneling, but assumed it would take some time before it managed to hit the market. Peratech, however, has already laid plans for its product to hit phones.

Peratech has created a 5-directional input device using QTC called Navikeys, and Samsung Electro-Mechanics appears to have developed a keen interest in it. Samsung EM is a major provider for cell phone components, so this means Navikeys could replace traditional input on many phones.

It also doesn’t seem like this will be too distant, as Peratech has already announced “Navikey using QTC from Samsung EM is already being used in a Tier 1 mobile phone”. Let’s hope applications of this might be expanded to netbooks and tablets in the near future as well.

Next Generation of Touchscreens Ready For Pressure

QTC
One of the greatest effects of the widespread success of the iPhone was the introduction of the capacitive touchscreen to the masses.  Capacitive screens gave us a more natural experience as opposed to the resistive interfaces from the past.  Now, there is much effort being spent towards the creation of pressure sensitive screens.  While there are many approaches towards this problem, one seems to claim that it is the end-all solution.

This comes from a specialized company called Peratech.  It is placing all of its money on a technology called quantum tunneling composite.  The way it works is by utilizing the fact that two conductors close to each other but separated by an insulating layer, will still cause electrons to jump back and forth. The special part is that they are using an polymer which reacts to the changes by pressure by changing its resistance.

Peratech has already signed on with a major screen maker and its products could hit the market by April of this year.  We will have to wait to see how they change the way we use touch interfaces till then.
