Numerical Analysis and Optimization on Piezoelectric Properties of 0–3 Type Piezoelectric Cement-Based Materials with Interdigitated Electrodes

Abstract

Abstract:The health conditions of complicated concrete structures require intrinsic cement-based sensors with a fast sensing response and high accuracy. In this paper, static, modal, harmonic, and transient dynamic analyses for the 0-3 type piezoelectric cement-based material with interdigitated electrodes (IEPCM) wafer were investigated using the ANSYS finite element numerical approach. Optimal design of the IEPCM was further implemented with electrode distance (P), electrode width (W), and wafer density (H) as the main parameters. Analysis results show that the maximum stress and strain in the x-polarization direction of the IEPCM are 2.6 and 3.19 times higher than that in the y-direction, respectively; there exists no repetition frequency phenomenon for the IEPCM. These indicate 0-3 type IEPCM possesses good orthotropic features, and lateral driving capacity notwithstanding, a hysteresis effect exists. Allowing for the wafer width (W p ) of 1 mm, the optimal design of the IEPCM wafer arrives at the best physical values of H, W and P are 6.2, 0.73 and 1.02 mm respectively, whereas the corresponding optimal volume is 10.9 mm 3 .

Electromechanical impact analysis of 2–2 cement-based piezoelectric sensor considering resistor

“…Liao et al discussed the mechanical performances of 2–2 cement-based piezoelectric sensor under instantaneous force without electrical components (Zhang et al, 2018). Lou et al (2017) studied the electromechanical capacities of 0–3 type cement-based piezoelectric sensor under static and dynamic response by numerical method. Wang et al compared the effect of electrical connection on piezoelectric cylindrical transducer under sinusoidal load, and the electromechanical characteristics of the sensor are verified in their later researches (Wang and Shi, 2014; Wang et al, 2019; Wang et al, 2018).…”

Intrinsic Sensing Properties of Chrysotile Fiber Reinforced Piezoelectric Cement-Based Composites

“…Li et al first introduced a cement admixture into pure PZT to fabricate a piezoelectric cement-based composite (PCM) to compensate for these disadvantages in 2002 [ 30 ]. Dong et al [ 31 , 32 ], Lan et al [ 33 ], Huang et al [ 34 ], Chaipanich et al [ 35 , 36 , 37 ], Gong et al [ 38 , 39 ], Pan et al [ 40 , 41 ], Luo et al [ 42 ], and Zhang et al [ 43 ] reported that, compared with 1–3, 2–2 type PCM sensor [ 31 , 33 ], the 0–3 type PCM sensor had more stable piezoelectric self-sensing behaviors with age and temperature treatment, superior compatibility and impedance-matching with concrete, where PZT granules were directly but randomly distributed in three dimension cement matrix without extra cutting and embedding processes [ 31 , 41 ]. Moreover, PZT powder in nanoscale can be facile pressed and sintered into PCM-based sensor or actuator for SHM with accurate stoichiometric composition, uniform morphology, and proper microstructure to ensure good interface compatibility and enhanced piezoelectric sensitivity [ 38 ].…”
