Variable capacitors may be useful, but the air gap that provides their capacitance is their greatest weakness. Rather than deal with the poor dielectric properties of air, some high-end variable ...

Philips’ researchers have micromachined electrically variable RF capacitors. The devices, which are the microscopic equivalent of air-spaced variable and switchable capacitors, can be integrated into ...

Capacitive displacement sensor’s touch-free nature makes it ideal for fragile surfaces and high-speed machinery.

The first British commercially available high-vacuum variable capacitors have been announced by the English Electric Valve Co. So 64 years ago, started a story in Electronics Weekly’s edition of March ...
