A lot of consumer gadgets use touch sensors now. It is a cheap and reliable way to replace a variety of knobs and switches on everything from headphones to automobiles. However, creating a custom ...

A cost-effective capacitive sensor system, SEN0193, was ruggedised, calibrated, and evaluated in both laboratory and field settings to assess sensor-to-sensor variability resulting from sensor ...

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 ...

Flexible capacitive pressure sensors have gained widespread application in health monitoring, robotics, and structural diagnostics. However, conventional designs that rely on flat or micropatterned ...

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 displacement sensors turn tiny gaps into actionable signals. By measuring changes in capacitance as target moves, these devices deliver precise, non-contact readings of position and motion.

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 ...
