“…The synthesis of phase PZT powder was prepared by means of a conventional solid-state reaction method 13 in which stoichiometric mixtures of metallic oxides were used, according to Equation ( 16), with commercially available PbO, ZrO 2 and TiO 2 , all of them having the Aldrich mark of high purity (> 99%). In the grinding process, the mixture was placed inside the polyacetal reactors, whose approximate volume is 221.69 cm 3 , containing approximately 98 g of zirconia beads per 10 g of reagents. In this process, the elimination of aggregates and/or reduction of particle size needs activation energy, so that the energy required in the reaction of the phase synthesis in the calcination process is lower.…”

In this study, the Pb(Zr0.65Ti0.35)O3 (PZT) structure was produced by the solid state reaction method, and a new polarization geometry was used to obtain the radial and thickness modes in cylindrical samples with more efficiency. The polarization procedure was investigated by varying the temperature from 30°C to 80°C. The experimental excitation of radial and thickness modes was observed, and a comparative study was performed with numerical simulations. The comparative analysis of the acoustic response of the cylindrical PZT samples under theoretical and experimental conditions was validated by COMSOL Multiphysics® software. The new polarization geometry technique was used to generate radial thickness and acoustic mixed modes with more efficiency. The results show that the resonance frequency and antiresonance, as well as the impedance mode and phase angle are well adjusted, showing the validation of the technique presented between the theoretical and experimental measurements.

“…[10][11][12] Several other studies have focused on improving the performance of piezoelectric material through compositional modifications, such as porosity, morphotropic phase boundary design, and doping ionic pairs have been reported in the literature. Qiao et al 13 increased the electromechanical coupling factor by 70% and the longitudinal piezoelectric coefficient (d 33 ) to 380pC/N of KNN-based ceramics by adding Bi 0.5 Na 0.5 Zr 0.15 Hf 0.75 O 3 (BNZH) compositions.

The present study proposes a 3-dimensional approach for enhancing the effective piezoelectric properties by poling orientation. The governing parameters for actuation and sensing applications are d 31 and d 31 ∕ 33 , respectively. The effective magnitudes of these parameters, i.e., d eff 31 and d eff 31 ∕ eff 33 , change with poling angles (roll and pitch angles). The combination of poling angles corresponding to the maximum magnitude of d eff 31 and d eff 31 ∕ eff 33 is called the optimum poling angle for piezoelectric materials. BaTiO 3 and KNN piezoelectric materials with tetragonal symmetry show an enhancement in d eff 31 ∕ eff 33 and d eff 31 at an optimized poling angle (roll angle). The piezoelectric material, 0.67Pb(Mg 1/3 Nb 2/3 )O 3 -0.33PbTiO 3 (PMN-0.33PT) with rhombohedral symmetry, shows a maximum improvement of 575% in d eff 31 ∕ eff 33at an optimum roll angle of 29° and a pitch angle of 60°. On the other hand, PMN-0.33PT shows an enhancement of 2034.44% in the d eff 31 coefficient at optimum roll and pitch angles of 50° and 60°. The effect of poling orientation on different piezoelectric materials with tetragonal and rhombohedral symmetry has been studied for actuation and sensing applications. The experimental approach to achieve inclination of dipoles through the placement of electrodes for different piezoelectric materials is also discussed.

It is desired to obtain a piezoceramic with a high piezoelectric coefficient and low dielectric loss simultaneously for energy harvester application. Herein, it is reported that the 0.025Pb(Mn1/3Nb2/3)O3‐0.525Pb(Ni1/3Nb2/3)O3‐0.135PbZrO3‐0.315PbTiO3 (PMNN‐PZT) ceramic exhibits superior piezoelectric charge parameter e33 of 37.74 pC m−2 and low dielectric loss tanδ of 0.45%. Furthermore, a PMNN‐PZT ceramic‐based magneto‐mechano‐electric coupled energy harvester (MMEC‐EH) with a varying‐stiffness cantilever is designed and fabricated, which shows the strong self‐resonance effect in response to a random, transient impulse vibration or magnetic field stimulus. The investigations show that under a 0.6 s pulse vibration stimulus, the MMEC‐EH can tune itself into self‐resonance damping oscillation lasting for six seconds at its resonance frequency of 16 Hz, and the produced maximum power is 1.96 mWRMS. Under both weak magnetic field and force‐field dual‐stimulus (Hac = 0.5 Oe and a = 0.05 g), the generated power density is about 60 mWRMS Oe−2g−2cm−3, which is one to two orders of magnitude higher than those previously reported MMEC‐EHs. Finally, the MMEC‐EH is successfully demonstrated to power temperature/humidity sensors, indicating its potential for harvesting both weak vibration and magnetic field energy from environments for self‐powered sensor application.
