Abstract: According to embodiments, an electric field sensor having a sensor electrode is constructed of an electrically conductive material and having one or more outwardly protruding pillars. A screen electrode overlies the sensor electrode and has one or more openings which register with the one or more pillars on the sensor electrode. At least one piezoelectric actuator is connected to the screen electrode so that, when excited by a voltage signal, the piezoelectric actuator modulates the screen electrode toward and away from the sensor electrode at the frequency of the periodic voltage signal. An output circuit configured to detect a voltage, a current output, or both, between the sensor electrode and the screen electrode which is proportional in magnitude to the strength of the electric field.

Abstract: An electric field sensor having at least a first and second electrically conductive generally planar electrodes that are spaced apart from each other. A circuit is electrically connected to the electrodes which is configured to generate an output signal proportional to a time derivative of a varying electric field surrounding the electrodes. Optionally, three sets of spaced apart electrodes which are arranged perpendicularly relative to each other are used for three-dimensional measurements of the electric field.
