1. An electric field sensor comprising:
an insulating substrate;
a plurality of electrodes disposed parallel to one another on the substrate;
an insulator disposed over the plurality of electrodes;
a plurality vias coupled to the plurality of electrodes and extending through the substrate
at a right angle to the plurality of electrodes; and
a ground ring disposed around the plurality of electrodes and the plurality of vias and configured to attenuate a sensitivity of the sensor to electric fields outwards of the ground ring;
wherein the insulator is configured to be mounted substantially flush with a surface of an aircraft engine.
