  2. Capacitive sensing - Wikipedia

    en.wikipedia.org/wiki/Capacitive_sensing

    Capacitive sensors are constructed from many different media, such as copper, indium tin oxide (ITO) and printed ink. Copper capacitive sensors can be implemented on standard FR4 PCBs as well as on flexible material. ITO allows the capacitive sensor to be up to 90% transparent (for one layer solutions, such as touch phone screens).

  3. Capacitive displacement sensor - Wikipedia

    en.wikipedia.org/wiki/Capacitive_displacement_sensor

    Capacitive displacement sensors can be used to measure the position of objects down to the nanometer level. This type of precise positioning is used in the semiconductor industry where silicon wafers need to be positioned for exposure. Capacitive sensors are also used to pre-focus the electron microscopes used in testing and examining the wafers.

  4. Capacitor discharge ignition - Wikipedia

    en.wikipedia.org/wiki/Capacitor_discharge_ignition

    Capacitor discharge ignition (CDI) or thyristor ignition is a type of automotive electronic ignition system which is widely used in outboard motors, motorcycles, lawn mowers, chainsaws, small engines, gas turbine-powered aircraft, and some cars.

  5. Capacitance probe - Wikipedia

    en.wikipedia.org/wiki/Capacitance_probe

    Each capacitor sensor consists of two metal rings mounted on the circuit board at some distance from the top of the access tube. These rings are a pair of electrodes, which form the plates of the capacitor with the soil acting as the dielectric in between. The plates are connected to an oscillator, consisting of an inductor and a capacitor. The ...

  6. Bubble sensor - Wikipedia

    en.wikipedia.org/wiki/Bubble_sensor

    Liquids have a higher dielectric constant than gas; when an air bubble is in a fluid-filled tube the capacitance is reduced and the output voltage rises. [3] The size of the bubble is inversely related to the measured capacitance. Table 1 shows an example of the characteristics of a particular capacitive sensor being researched. [4]

  7. Force-sensing capacitor - Wikipedia

    en.wikipedia.org/wiki/Force-sensing_capacitor

    SingleTact makes force-sensitive capacitors using moulded silicon between two layers of polyimide to construct a 0.35 mm thick sensor, with force ranges from 1 N to 450 N. [3] The 8mm SingleTact has a nominal capacitance of 75 pF, which increases by 2.2 pF when the rated force is applied. [3]

  9. Three-dimensional electrical capacitance tomography - Wikipedia

    en.wikipedia.org/wiki/Three-dimensional...

    These long wavelengths allow the technology to operate under the quasi-electrostatic regime. As long as the diameter of the sensor is much smaller than the length of the wave, these assumptions hold valid. For instance, when exciting with 2 MHz AC signal, the wavelength is 149.9 meters. Sensor diameters are typically designed well below this limit.
