What is capacitive touch and what can it be used for

Conventional mechanical buttons or potentiometers with moving parts have a certain lifetime. Sooner or later they are worn out and do not work reliable anymore. Due to the lack of moving parts, capacitive touch is much more durable. However for highly stressed elements, the surface resp. overlay cover material of the touch electrode has to be considered. Glass or acryl may be better suited as plastics. For single, isolated buttons, even metal can be used, not for complete front covers however as the sensor pads must be isolated from each other. One positive aspect of the moving parts in conventional push buttons or switches is the tactile feedback to the user. By touching a surface, the user does not “feel” if the push button was triggered. This can be compensated by using optical, acoustical or, a bit more complex, vibration feedback.
