You can’t have a touch sensitive switch without a way to detect the presence of a finger! A touch sensor, especially a capacitive touch sensor, has some surprisingly sophisticated electronics to ...

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 ...

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 ...

As discussed in the first part of the article, the accuracy with which sensor capacitance can be measured using absolute capacitance measurement has a significant dependency on the accuracy of the ...

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 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 ...

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 ...
