Abstract: A pipeline breach monitor includes an electric field sensor and a signal processing unit in communication with the electric field sensor. The electric field sensor includes an upper substrate, and a plurality of electrodes embedded in the upper substrate. The electrodes are substantially parallel to each other in the upper substrate and comprise at least one sense electrode and a plurality of elongate sensor electrodes disposed around the at least one sense electrode. The signal processing unit is configured to (i) apply a voltage signal to the sensor electrodes, (ii) receive at least one measurement set comprising a measurement of a phase and a magnitude of a current generated in the at least one sense electrode and the sensor electrodes, and (iii) generate an assessment of accumulation of a substance proximate the electric field sensor from the at least one measurement set and at least one predetermined substance accumulation profile.
