Abstract
In various embodiments, an apparatus for detecting electric fields is disclosed that includes an array of non-linear elements configured into an oscillator with each coupled to one or more electric-field sensing plates. In various embodiments, an output of the array produces a frequency that varies as a function of an electric field sensed by the one or more electric-field sensing plates.
