The QTC technology detects pressure touch inputs opening up the possibility of 3D interfaces and improved handwriting recognition
As QTC is compressed the metal filler particles are brought closer together allowing electrical conduction
The spikes on the metal filler particles cause localized high electric fields at their tips
Touchscreens found in most mobile devices today use capacitance or resistance technology - fine for detecting input from a finger, but not so great when it comes to detecting how much pressure that finger is applying. However, this limitation could be about to change with news that Japanese touch screen manufacturer, Nissha, has licensed new technology that allows a touchscreen to detect pressure, even from a finger. This adds a third dimension to touchscreen interaction and opens up a raft of potential applications.
