Abstract

An electric field sensor comprises an insulating substrate, a plurality of non-contacting electrodes disposed on the substrate, and a plurality of conductors coupled to the electrodes, and extending transversely through the substrate. The electrodes comprise a first electrode portion, and a second electrode portion interlaced with the first electrode portion. The conductors comprise a first conductor portion and a second conductor portion. The first portion of the conductors are coupled to the first electrode portion. The second portion of the conductors are coupled to the second electrode portion.
