Ever wondered how a touch-sensitive screen works? The answer is capacitive sensing, which can detect the presence of your finger through the protective glass sheet and doesn't require any pressure.

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 ...

Liquid-level sensing based on capacitive sensors comes with its own challenges. It’s like absolute capacitance sensing. Unlike touch detection, the absolute value of the liquid level needs to be ...

Capacitive sensors work by using the human body as one of the capacitive plates of an electrical circuit. A leader in low power capacitance touch sensors, NXP offers a range of auto calibrating ...

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 ...

The DS-2100 and the DS-2100 WiFi displays from Loadstar Sensors Inc. are load indicators designed to work seamlessly with the company's patented capacitive load sensors. The DS-2100 and the DS-2100 ...

Apple is examining a shift from a force sensor in AirPods to a capacitive touch system to make a set easier to control, and provide new options. The latest in Apple's surprisingly long history of ...

If you’ve got a smart home, or you just want to know how soaked your garden is getting in the winter, you might want to measure rainfall. There are a bunch of ways to go about it, and this capacitive ...
