What is Capacitive Touch Technology?
The most prominent capacitive interface is on a mobile device such as a tablet or mobile phone. When we swipe, pinch or otherwise touch the screen with our finger the internal electric field structure is changed. Instead of interpreting mouse clicks and keyboard strokes, the locations of these field changes are relayed to the device’s processor, which interprets the movement to perform a function.
Due to the large investment in tooling, custom capacitive interfaces have predominantly been used for high volume consumer products. However, enhanced driver devices and simpler implementation allows capacitive touch to be considered for lower volume industrial applications with display or as discrete switches. As well as providing a clean and flexible interface, user familiarity from consumer goods aides customer acceptance in the field.
