In electronics, capacitive coupling is the transfer of energy from one circuit to another by means of the mutual capacitance between the circuits. This can be an intentional or accidental effect. It only works well enough to be of practical use in relatively short ranges, such as some RFID applications. Two digital voltmeters The field of electronics is the study and use of electronic devices that operate by controlling the flow of electrons or other electrically charged particles in devices such as thermionic valves and semiconductors. ...

Capacitive coupling favors transfer of the higher frequency components of a signal, whereas inductive coupling favors lower frequency components, and conductive coupling favors neither higher nor lower frequency components. Sine waves of various frequencies; the lower waves have higher frequencies than those above. ... Signaling, or a signal, may mean: Look up signal in Wiktionary, the free dictionary Scientific concepts In information theory, a signal is a flow of information that can be represented as a mathematical function. ... In electronics, inductive coupling refers to the transfer of energy from one circuit component to another through a shared magnetic field. ... Conductive coupling: Energy transfer achieved by means of physical contact, coupling other than inductive or capacitive coupling. ...

"Gimmick" is the name of a very simple kind of capacitive coupling. All it is is a piece of wire that is attached to another one, not connected, but the insulation of both is in-between, providing a capacitive coupling between the two circuits, just a very few Picofarads in value. Maybe there are several turns of wire, as required. The picofarad (pronounced or ) is the smallest measurable unit of electrical capacitance. ...
