“…The main reasons are as follows. The previous works have proved that the damage indexes RMSD, MAPD, and CCD can be used to evaluate the structure damage [16,30,63]. However, the calculation of these damage indexes is highly dependent on the correct selection of the frequency range, and the frequency range needs to include dominant peaks and dominant valleys to include more information about the dynamics of the structure.…”

“…Over the past few decades, electromechanical impedance (EMI) technique based on piezoelectric ceramic materials has been widely studied in various applications [14,15], such as pressure vessel internal rupture disc working condition monitoring [16], real-time monitoring of concrete modulus and internal friction [17], loose bolt identification [18,19], concrete crack identification and monitoring [20,21], carbon fiber reinforced polymer panel damage monitoring [22], corrosion damage monitoring of reinforced concrete beams [23], evaluation of soft soil strength development during freezethaw process [24], monitoring of corrosion-induced thickness loss for stainless steel plates [25], assessment of radiation from structural damage [26]. The EMI technique is based on both positive and inverse piezoelectric effects.…”

Rod-type metal corrosion probes based on electromechanical impedance (EMI) technique can quantitatively assess the amount of corrosion, which have a promising application in pipeline corrosion monitoring and have received more and more attention. In the design of piezoelectric smart devices, electrical series and parallel connections are very important and effective adjust method to improve the device performance, but it is yet to be used in the probe design. In this work, a kind of novel metal corrosion probe with two piezoelectric elements in series and parallel connections was proposed, and its performance was investigated comprehensively by combining theoretical analysis with experiment research. Theoretical models of the proposed probe in the longitudinal vibration mode for both series and parallel connections were established, and verified by the experimental results. Influences of the thicknesses of piezoelectric layer and ceramic layer on the probe performance were analyzed. Artificial quantitative corrosion tests and accelerated corrosion tests were designed to evaluate the quantitative corrosion monitoring capacity. Temperature sensitivity tests were conducted to study the temperature dependence. The wireless impedance measurement was performed to confirm the online monitoring ability. Comparisons for the probe performance between the series and parallel connections were also presented. This work provided a comprehensive understanding for this kind of novel probe, which is beneficial to develop low-cost, high-precision, high-stability pipeline corrosion real-time monitoring technology.

“…Ai et al used this method to compensate the temperature effect in damage monitoring of concrete tunnelsegment structure, and good compensation effect has been achieved [76]. Chen et al investigated the influences of temperature variation on EMI signals in rupture disc monitoring, and proposed that this method is effective for the temperature compensation [77]. Baral et al employed this method in condition monitoring of metallic structures, and experimentally validated its capacity in determining the actual condition of the structure by compensating the vertical and horizontal shift in admittance signatures of piezo sensors at different temperatures [78].…”

Cracks will inevitably occur in concrete structures or members during the construction process and service life due to aging, environmental factors, external loads, etc. To improve the strength and stability of the cracked concrete structures, many methods have been proposed to repair the cracks. However, the monitoring of the repairing process and repair quality has not been fully studied. The previous studies have proved that the SSAs based on the electromechanical impedance (EMI) technique have outperformed the traditional SAs based on the EMI technique in structural health monitoring of civil structures, however, SSAs have not been applied to the monitoring of the concrete crack repair. In this work, the monitoring of the concrete crack repair using the SSAs based on the EMI technique was explored. A total of 8 valid concrete specimens were prepared, and cracks in the concrete specimens were simulated by manually cutting under laboratory conditions. According to the principle of grouting method, two repair agents including cement paste and cement mortar were used to repair the cracks. The impedance signals of 28 days were measured, and three quantitative indicators root mean square deviation (RMSD), mean absolute percentage deviation (MAPD), and correlation coefficient deviation (CCD) were used to evaluate the quality of the concrete repair effect. The results indicate that the SSAs show excellent sensitivity and stability over the traditional SAs. In addition, the normalization values of the quantitative indicators were analyzed to distinguish the types of repair agents. A mathematical expression of exponential function was also proposed by fitting the experimental data to quantitatively evaluate and predict the repair effect of concrete cracks.
