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.
