Capacitive Sensing Circuit

Capacitive sensing circuit

Capacitive Sensing

A capacitor is simply two conductors with an insulator in between. This allows for a charge to be stored and then discharged. This also lets changes in its capacitance be sensed, such as a finger coming into contact with a copper pad. The capacitive sensing circuit also means the touch circuits, similar like a touch screen, but not used as the surface components. There you also can assembly the thicker plastic plate/glass upon the sensing circuit. The capacitive sensing circuit can have a very long life-time and also good a good transmittance.22
