Capacitive proximity sensor block diagram Capacitive proximity sensors use two metal electrodes or plates to generate a high-frequency electrostatic field.

Capacitive sensors use a cantilevered beam with moving parts. They are inherently wideband transducers (>5 kHz), with a mechanical resonant frequency near 2 kHz for low-g devices used to detect ...

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 ...

For context, Queensgate’s NanoSensor product portfolio comprises an established family of non-contact position measuring systems (the NX series) based on the principle of capacitance micrometry. Two ...

The superior capacitive sensors can't go under your screen yet, and ultrasonic technology is still relatively new and expensive. Thus the optical scanner saw a resurgence in popularity.
