Liquid-level sensing is used in consumer electronics appliances like washing machines to detect the detergent level. The sensor technolo­gy has progressed to such an extent that refrigerators can now ...

The following guide provides a review of the types of proximity sensors for prolonged detection, followed by a look at capacitive sensing design specifically for occupancy-type solutions. A variety of ...

Depending upon the distance between the surface of a capacitance probe and a target source, the electrical capacitance that is formed between these two objects will vary. In an effort to improve ...

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 ...

This paper describes the design and characterisation of a long-range capacitive displacement sensor, NanoSensor® model NXE2. Special emphasis is placed on the design features and metrological ...

One of the main strengths of capacitive tactile sensing technology is its ability to help people access information that would otherwise be impossible to capture. Consider, for example, a ...

3M Touch Systems announces the commercial availability of a new polyester-based projected capacitive touch screen solution. MicroTouch Flex Capacitive Touch Sensors from 3M are ideal for high-volume ...

There are generally two types of accelerometers currently available—capacitor-based and thermal versions—and both are microelectromechanical devices (MEMS). So what’s the difference between the two?
