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 ...

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 ...

With the introduction of the first smartphones in 2012 with in-cell touch displays, a battle is emerging between the traditional supply chain of ITO-based touch sensors that are externally combined ...

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 ...

In many soft sensor systems, external wires for connecting the sensors to control circuits have posed practical problems, in terms of compact form factors and physical robustness. This study proposes ...

Non-contact displacement measurements can be made rapidly and with high precision using capacitive sensors over a modest range. The main features are: Capacitive sensing is a non-contact measurement ...

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.

Inductive sensors are non-contact proximity sensors that detect ferrous targets, ideally ones made of mild steel thicker than one millimeter. They consist of four major components: a ferrite core with ...
