Wanting to save space and weight on his project build [Florin] set out to find a way to add Ethernet connectivity without the magnetics. His ill-advised first try involved directly coupling two swi… ...

It works by using capacitive coupling between the signal you wish to sample and a high impedance output. The latter can then safely be connected to an oscilloscope or spectrum analyzer for monitoring.

If you think carefully about capacitive coupling, the answer is obvious. The hot and neutral conductors are lying side by side for the complete distance from the outlet back to the panel.

Comparison of position displacement efficiency in electromagnetic induction and capacitive coupling (DC input – DC output) Methods of wireless charging based on components available on the market ...

RF coupling is one of the most important and tricky issues that RFIC designers always must confront while developing wireless SoCs.

Teradyne (Munich, Germany) has announced FrameScan FX, a vectorless test tool for detecting open pins on components and connectors assembled onto PCBs. The test tool uses in-circuit capacitive ...

An especially helpful feature is the Klein meter's LoZ, or low impedance, setting. Ordinary meters can indicate a voltage when none is present due to a phenomenon known as capacitive coupling.

Capacitive and inductive coupling stimulation therapies are noninvasive. With capacitive coupling stimulation, two small electrode pads are placed on the skin over the region of desired bone fusion.
