The way they work is ingenious. Layers of silicone are sandwiched between two lengths of silver-plated conductive fabric forming — by some approximation — a capacitance sensor.

A capacitance proximity sensor most often used for industrial automation is mounted in the wooden base. He just calls it “an NPN capacitive sensor” without mentioning part number but these are ...

The 16-bit AD7142 capacitance-to-digital converter (CDC) relies on a capacitance-sensor core to provide error-free performance in low-power mobile applications. With 14 inputs paired with adaptive ...
