    What is capacitive sensing and how does it work?
    Capacitive sensing is a technology based on capacitive coupling that takes the capacitance produced by the human body as the input. It allows a more reliable solution for applications to measure liquid levels, material composition, mechanical buttons, and human-to-machine interfaces.

    What is a capacitive sensor?
    What is a capacitive sensor? A capacitive sensor is an electronic device that can detect solid or liquid targets without physical contact. To detect these targets, capacitive sensors emit an electrical field from the sensing end of the sensor. Any target that can disrupt this electrical field can be detected by a capacitive sensor.

    What do you know about capacitive voltage sensors?
    Capacitive sensors are usually tolerant of temporary over-pressure conditions. They have low hysteresis with good repeatability and are not very sensitive to temperature changes. On the other hand, capacitive sensors have non-linear output, although this can be reduced in touch-mode devices. However, this may come at the cost of greater hysteresis.

      • I don't think that is entirely true. Objects can be equipped with conductive material that then can act as a conductor when the user touches that object. This is shown for example in the paper "SmartSkin: an infrastructure for freehand manipulation on interactive surfaces" where the term "capacitance tags" is coined. But I don't know right now how ...
