In the past, capacitive sensors for automotive electronics were rarely used, as they were deemed to be hard to control, difficult to read out, sensitive to aging, and temperature dependent. On the ...

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 ...

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 ...

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 ...

Capacitive sensing offers developers a new way to interact with users that overcome the traditional problems associated with mechanical levels or push button switches that engage a solenoid controlled ...

The review briefly introduces the principle, material selection criteria, and development of the thermal drawing process. Based on different stimuli, the review comprehensively summarizes the latest ...
