Simple, low cost and low consumption devices are required in medical applications. In Dr. Luis Moreno-Hagelsieb's laboratory, aluminum oxide interdigitated capacitors have been developed and ...

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 touch screen technology underpins many modern interactive devices by utilising the inherent ability of certain materials to store and transfer electrical charges. The operation of these ...

Capacitive sensors are typically cost-effective and deliver low-power performance features aligned with today’s trends for consumer and industrial applications. Capacitive sensors are cost effective ...

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 ...

Capacitive sensors supply high accuracy at a relatively low cost. But system designers attempting to use them have been forced to first convert the capacitance to a voltage, then convert the voltage ...
