Abstract
An electric field detecting system is provided that comprises a first metal plate, a second metal plate, a sensor and a detector. The sensor has a first metal layer, a second metal layer and a non-linear permittivity dielectric material disposed between the first metal layer and the second metal layer. The first metal layer is electrically connected to the first metal plate, whereas the second metal layer is electrically connected to the second metal plate. The detector can detect a voltage between the first metal layer and the second metal layer and can determine a magnitude of the electric field based on the detected voltage and a priori information related to a variable capacitance of the non-linear permittivity dielectric material.
