2. Capacitive sensing - Wikipedia

   en.wikipedia.org/wiki/Capacitive_sensing

   Self-capacitance sensors can have the same X-Y grid as mutual capacitance sensors, but the columns and rows operate independently. With self-capacitance, current senses the capacitive load of a finger on each column or row.

3. Capacitive displacement sensor - Wikipedia

   en.wikipedia.org/wiki/Capacitive_displacement_sensor

   Capacitive displacement sensors share many similarities to eddy current (or inductive) displacement sensors; however capacitive sensors use an electric field as opposed to the magnetic field used by eddy current sensors [10] [11] This leads to a variety of differences between the two sensing technologies, with the most notable differences being ...

5. Transimpedance amplifier - Wikipedia

   en.wikipedia.org/wiki/Transimpedance_amplifier

   The sensors which transimpedance amplifiers are used with usually have more capacitance than an op-amp can handle. The sensor can be modeled as a current source and a capacitor C i. [4] This capacitance across the input terminals of the op-amp, which includes the internal capacitance of the op-amp, introduces a low-pass filter in the feedback path.

6. Current sensing - Wikipedia

   en.wikipedia.org/wiki/Current_sensing

   The design of the saturable inductor current sensor is similar to that of a closed-loop Hall-effect current sensor; the only difference is that this method uses the saturable inductor instead of the Hall-effect sensor in the air gap. Saturable inductor current sensor is based on the detection of an inductance change. The saturable inductor is ...

7. Capacitance probe - Wikipedia

   en.wikipedia.org/wiki/Capacitance_probe

   Capacitance sensors (or Dielectric sensors) use capacitance to measure the dielectric permittivity of a surrounding medium. The configuration is like the neutron probe where an access tube made of PVC is installed in the soil ; probes can also be modular (comb-like) and connected to a logger.
