With the introduction of iPad and many Touch devices its clear that Touch is the future. We at present have the Resistive and capacitive touchscreens. The resistive screens are way more accurate, but needs pressure to be applied and are generally less responsive. On the other side the capacitive screens require only slight touch to register a click, allow multi-touch gestures by default, but lack accuracy and cannot be used with gloves, styluses or if you have long nails.To bridge the gap we now have the next touchscreen technology that will have a go at conquering the mobile world. Pressure-sensitive touchscreens can tell the difference between a slight touch and a really hard poke. That would allow a whole new user experience, with gestures based on the amount of pressure applied, along with ones currently available. The new technology is based on quantum tunneling and is developed by the Peratech researchers (stationed in UK). It uses an electrically conductive material named a quantum tunneling composite. But we won’t go any deeper in the physics side of things.

The important thing to note is that Peratech make pressure sensors from this material, which are incredibly thin and can be slipped under any touchscreens. They don’t draw any power when idle so you shouldn’t worry about battery life either. Some of the supposed new gestures will allow you to drag and zoom pictures simultaneously or determine the scroll speed based on your pressure force.
