CAPACITIVE-RESISTIVE IMAGING SYSTEM

Abstract: a capacitive-resistive imaging system for imaging an environment can include a plurality of conductive electrodes supported on a substrate, and have a side directed away from the substrate, wherein the conductive electrodes are, in use, galvanically isolated from the environment to be imaged, and capacitively couple thereto, and have a dielectric coating on at least the side directed away from the substrate. the dielectric coating advantageously can be higher than 6, and more advantageously is much greater than 6. this encourages an electric field induced into the environment from the electrodes to penetrate further into the environment, and reduces coupling to the substrate. the disclosed subject matter has application in down-hole imaging, monitoring of constructions, foundations, and elsewhere.
