Development of a Novel Corrosion Sensor Based on Electromechnical Impedance Instrumented Piezoelectric-Metal Transducer
Publication: Earth and Space 2021
ABSTRACT
Corrosion of metallic materials accounts for most of the structural failures across multiple industries. In this paper, a novel corrosion sensor was proposed based on the piezoelectric-metal transducer using electromechanical impedance (EMI). The corrosion sensor consisted of a metal plate with a lead-zirconate-titanate (PZT) patch of the same cross section attached to it. Due to the electromechanical coupling effect, under the alternating electric field excitation, the in-plate contraction and extension of the PZT patch induces bending vibration of the piezoelectric-metal transducer. Corrosion-induced thickness loss of the piezoelectric-metal transducer reduces its bending rigidity and thus the bending resonant frequencies, which are measured by the electromechanical impedance technique. Finite-element simulation and experimental investigation were performed to validate the proposed corrosion sensor. Results showed that the proposed corrosion sensor is able to determine the corrosion-induced thickness loss quantitatively, which shows promising application potential.
