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 ...
Using metamaterials, light-driven additive manufacturing, and other techniques, researchers have created innovative pressure ...
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 ...
In Part I of this series, we explored the differences between user interfaces based on mechanical buttons and those utilizing capacitive touch sensors. In Step 1 we discussed the look and feel of a ...
The global capacitive sensors market is witnessing significant expansion, driven by the increasing adoption of multi-touch capacitive sensing technology in consumer electronics, automotive, and ...
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?
The capacitance-based pressure sensor line by Alpha Instruments measures from 0.1-100 inches of water column (wc). All models have a bidirectional version, making them well suited for applications ...
There are few things more frustrating than being in the middle of working on a project and realizing that you are missing some crucial component that ties the whole thing together. According to Murphy ...
