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 ...

Most proximity sensors use an electromagnetic field to sense the presence of a target metal. But there are times when it's necessary to sense nonmetallic materials such as plastics, liquids, or ...

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 touch sensors are based on the electrical capacitance of the human body. When, for example, a finger comes close to the sensor, it creates a capacitance to Earth with a value of 30 to 100 ...

EBE sensors + motion is expanding its portfolio of capacitive input systems for industrial control concepts with the TCRC.

From Disney World to the smartphone in your pocket, fingerprint scanners have become commonplace these days. Even budget phones sport the tech, sometimes alongside other biometric unlocking options ...
