  2. Touch switch - Wikipedia

    en.wikipedia.org/wiki/Touch_switch

    Touch switch. A touch switch is a type of switch that only has to be touched by an object to operate. It is used in many lamps and wall switches that have a metal exterior as well as on public computer terminals. A touchscreen includes an array of touch switches on a display. A touch switch is the simplest kind of tactile sensor.

  3. Tactile sensor - Wikipedia

    en.wikipedia.org/wiki/Tactile_sensor

    A PPS tactile sensor system (TactileHead []) designed to quantify the pressure distribution over the face and head. Useful to optimise the ergonomic design of headgear and eyewear. The SynTouch BioTac, [2] a multimodal tactile sensor modeled after the human fingertip. A tactile sensor is a device that measures information arising from physical ...

  4. Touch-sensitive lamp - Wikipedia

    en.wikipedia.org/wiki/Touch-sensitive_lamp

    A touch-sensitive lamp is a combination of a lamp and a touch switch. They act on the principle of body capacitance, activated by human touch rather than a flip, push-button, or other mechanical switch. They are popular as desk and nightstand lamps. Touch-sensitive lamp switches may be dimmable, allowing the brightness of the lamp to be ...

  5. Capacitive sensing - Wikipedia

    en.wikipedia.org/wiki/Capacitive_sensing

    Capacitive sensing. In electrical engineering, capacitive sensing (sometimes capacitance sensing) is a technology, based on capacitive coupling, that can detect and measure anything that is conductive or has a dielectric constant different from air. Many types of sensors use capacitive sensing, including sensors to detect and measure proximity ...

  6. Proximity sensor - Wikipedia

    en.wikipedia.org/wiki/Proximity_sensor

    Proximity sensors are also used in machine vibration monitoring to measure the variation in distance between a shaft and its support bearing. This is common in large steam turbines, compressors, and motors that use sleeve-type bearings. A proximity sensor adjusted to a very short range is often used as a touch switch.

  8. Inductive sensor - Wikipedia

    en.wikipedia.org/wiki/Inductive_sensor

    An inductive proximity sensor is a non-contact electronic proximity sensor. It is used for positioning and detection of metal objects. The sensing range of an inductive switch is dependent on the type of metal being detected. Ferrous metals, such as iron and steel, allow for a longer sensing range, while nonferrous metals, such as aluminum and ...

  9. Piezoelectric sensor - Wikipedia

    en.wikipedia.org/wiki/Piezoelectric_sensor

    Piezoelectric sensor. A piezoelectric disk generates a voltage when deformed (change in shape is greatly exaggerated) A piezoelectric sensor is a device that uses the piezoelectric effect to measure changes in pressure, acceleration, temperature, strain, or force by converting them to an electrical charge. The prefix piezo- is Greek for 'press ...
