“…Figure 5 highlights the frequency shift through the different damage stages. It was evident that higher frequencies within the frequency range used were more sensitive to detecting increasing damage than lower frequencies [37]. Even though peak numbers P2 to P5 clearly showed a higher resonance frequency for the pristine stage, damage stage 1 to damage stage 5 showed equal resonance frequency values, regardless of the increasing damage.…”

Lead zirconium titanate (PZT) has recently emerged as a low-cost material for non-destructive monitoring for civil structures. Despite the numerous studies employing PZT transducers for structural health monitoring, no studies have assessed the effects of both damage and repair on the electromechanical impedance response in cementitious materials. To this end, this study was conducted to assess the effects of the damage and repair of mortar samples on the electromechanical response of a surface-mounted PZT transducer. When damage was introduced to the specimen in stages, the resonance frequencies of the admittance signature were shifted to lower frequencies as the damage increased, and an increase in the peak amplitude was detected, indicating an increase in the damping and a reduction in the material stiffness properties. Also, increasing the damage in the material has been shown to decrease the sensitivity of the PZT to further damage. During the repair process, a noticeable difference between the after-damage and the after-repair admittance signatures was noted. The root-mean-square deviation (RMSD) showed a decreasing trend during the repair process, when compared to the before repair RMSD response which indicated a partial recovery for the material properties by decreasing the damping property in the material.

“…The piezoelectric properties of piezoelectric materials are mainly controlled by element doping. The development of an inorganic piezoelectric material system has gone through two stages: single component (such as BaTiO 3 [ 31 ] and PbTiO 3 [ 32 ]) and morphotropic phase boundary (such as lead zirconate titanate (PZT) [ 33 , 34 ], (1-x)Pb(Mg 1/3 Nb 2/3 )O 3 -xPbTiO 3 (PMN-PT) [ 35 ], and Ba(Zr 0.2 Ti 0.8 )O 3 -x(Ba 0.7 Ca 0.3 )TiO 3 (BCT-BZT) [ 36 ]). With the development of material systems, the properties of inorganic piezoelectric materials have been greatly improved.…”

Structural health monitoring technology can assess the status and integrity of structures in real time by advanced sensors, evaluate the remaining life of structure, and make the maintenance decisions on the structures. Piezoelectric materials, which can yield electrical output in response to mechanical strain/stress, are at the heart of structural health monitoring. Here, we present an overview of the recent progress in piezoelectric materials and sensors for structural health monitoring. The article commences with a brief introduction of the fundamental physical science of piezoelectric effect. Emphases are placed on the piezoelectric materials engineered by various strategies and the applications of piezoelectric sensors for structural health monitoring. Finally, challenges along with opportunities for future research and development of high-performance piezoelectric materials and sensors for structural health monitoring are highlighted.

“…While some systems have low k 2 values, the predicted values of HQReO 4 of 0.75 and [Hdabco]ReO 4 of 0.79 exceed those of PZT-5H (a commercial PZT composition), AlN, and PVDF-TrFE with values 0.76, 0.23, and 0.45, respectively. 16,102,103 The large piezoelectric figures of merit for some of the plastic ionic molecular crystals can be explained by their small dielectric constants and large mechanical compliance. PZT-5H has a d 33 of 593 pC/N and a relative permittivity of 3400, 7 while all of the plastic crystals studied in this work have dielectric constants below 5.…”

Plastic ionic molecular crystals are a novel class of materials that have attracted recent interest due to the discovery of ferroelectric and piezoelectric properties together with an orientationally disordered mesophase with high plasticity. Despite the growing interest, little is known about the mechanisms that underpin their piezoelectric properties. To address this knowledge gap, we use density functional theory calculations with van der Waals density functionals to study the dielectric, piezoelectric, and elastic properties of 11 plastic ionic molecular crystals. The piezoelectric coefficients were found to reach values comparable to inorganic piezoelectrics. Further, some plastic crystals have strikingly large piezoelectric anisotropies. For HQReO4 (quinuclidinium perrhenate) an anisotropy of |d 16/d 33| = 118 was found, 11 times that of LiNbO3, a phase pure inorganic noted for its anisotropy. Our study links the anisotropy to the rotational motion of the constituent molecules in response to shear stress. The large shear piezoelectric coefficients, yet modest dielectric permittivity, results in coupling coefficientsa measure of its suitability for energy harvestingwith values up to 0.79. Our study points to the engineering of the rotational response of plastic ionic crystals as key to realizing the outstanding functional properties of these compounds.
