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 ...

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 ...

Capacitive touch technology has made tremendous inroads into a wide range of applications since its introduction to the market. Touch technology began with resistive touch screens used in the first ...

There is a basic method for measuring high-frequency power using a power meter and power sensor (Fig. 1). The power sensor converts high-frequency power to a dc or low-frequency signal that the power ...
