Tick tracer. Glow meter. Sniffer. They go by many names, but capacitive voltage sensors are all designed to do one thing: detect the presence of voltage in a wire or piece of equipment without ...

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 ...

Mobile devices such as tablets and cellphones generally require proximity sensors for Specific Absorption Ratio (SAR) qualification and on-ear detection. Capacitive sensing may be used to meet both of ...

Many billions of mechanical buttons in cell phones, cars audio systems, notebooks, PCs, white goods, and industrial applications have been replaced with capacitive sensing buttons. The use of ...

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 ...
