Electrostatic coupling

Electrostatic coupling is the transfer or influence of electrical energy between conductive parts through electric fields, without direct contact. It occurs when two components are close enough that the electric field generated by one affects the other, causing unintended interference or signal transfer. This phenomenon is common in electronic devices and circuits, where it can lead to noise or signal crosstalk, and designers often incorporate shielding or spacing to minimize its effects. Essentially, electrostatic coupling is the way static electrical influences can pass through space, affecting nearby components even without physical connection.
