Performance evaluation of electro-mechanical impedance based state of health estimation of sacrificial anodes in reinforced concrete structures

This study demonstrates that electro-mechanical impedance (EMI) sensing with PZT transducers can sensitively track the state-of-health of sacrificial anodes embedded in concrete. The RMSD of conductance spectra offers a non-destructive, real-time metric for monitoring anode degradation.

Monitoring Corrosion in Sacrificial Anodes With Pulsed Eddy Current and Electromechanical Impedance: A Comparative Analysis

A head-to-head comparison of pulsed eddy current (PEC) and electro-mechanical impedance (EMI) techniques for quantifying corrosion of zinc sacrificial anodes. Experiments and FEM show EMI is highly sensitive to incipient corrosion while PEC provides linear tracking over anode lifetime — suggesting a combined sensing strategy.

Vibration-based inverse graphical technique for thickness estimation of bulk acoustic wave (BAW) resonators: application for corrosion monitoring of sacrificial anodes

This paper proposes a calibration-free graphical method to estimate zinc and zinc-oxide layer thicknesses on sacrificial anodes from bulk acoustic wave resonances. Validated with finite element analysis and accelerated corrosion experiments, the approach offers a simple and reliable tool for real-time anode health monitoring.
