Capacitive sensing offers an intuitive and robustinterface that increases product reliabilityby eliminating mechanical parts in manyappliances, or white goods, and instruments.Because of their ...

Capacitive sensors work by detecting the change of capacitance introduced by the finger touching near the electrode. Such change is so small that detecting it unambiguously is challenging, and has ...

This PLL-based circuit implements a touch-switch circuit using the PC board or small metal pads as sensors; it is radiometric and thus insensitive to changes in temperature and supply voltage.

Capacitive sensing is a contactless-sensing technique with numerous applications, ranging from proximity sensing (Fig. 1), gesture recognition, automotive rain sensors, and remote liquid-level sensing ...

Capacitive-commutation techniques now replace optical and Hall-effect circuitry in brushless-dc motors. • Capacitive sensing offers low operating currents, broad programmability, excellent temperature ...
