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 ...
Designing with high-fidelity capacitive proximity sensors requires careful consideration of mechanical design, sensor placement/design, and end-application operating environments. Careful evaluation ...
Proximity detection adds many smart features to the devices we use.For example, when making a call with a phone held to your ear, face detection using proximity sensing can disable the touchscreen and ...
