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 ...

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 ...

In the last Sensor Sense we looked at capacitive touch switches used for on/off control. But these switches are also found in capacitive touch sliders that can control various levels, such as volume ...

• Trapped acoustic resonance is most simply described with an analogy: the ringing of a bell. • Microprocessors control the frequency of the mechanical resonance and monitors its decay. • A thicker ...

Capacitive touch-sensing user interfaces are replacing mechanical buttons in products across consumer, medical and industrial segments. However, with the advent of touch-sensing user interfaces, ...
