“…The piezoelectric charge coefficient d and the permittivity at constant stress ò T describe the response of piezoceramics to the applied electric field. A number of extensive studies have already been focused on the nonlinear behavior of piezoceramic materials at high electric fields and are summarized in [15], whereas nonlinear constitutive relations for piezoceramic materials can be found in [16]. Wang et al measured the nonlinear behavior of PZT 3203 HD from Motorola, classified as soft PZT ceramic, up to an electric field of 0.15 kV mm −1 by measuring the tip deflection and blocking force of cantilever beams using an optical fiber displacement sensor and a force load cell, respectively [17].…”

In this paper, we compare the performance of 8 PZT ceramics and one PMN-PT material for typical bending actuator applications. This includes the measurement of nonlinear transverse charge coefficient at high electric field strength and related quantities such as the Young's modulus, relative permittivity, coercive field and their temperature dependencies, and the Curie temperature. Most materials show much higher strains than what is expected from the datasheet values. We further study the operating region for fields against the polarization direction in different operating cycles and demonstrate a long-term stable quick re-poling method which increases the operating range of negative-only cycles from 50% of E c to 66% of E c .

“…From the heating curves in Fig. 11, it is known that the dielectric coefficients [28] and heating characteristics of the two are different when a hybrid susceptor is used. In addition, it can be found from reactions (1) and ( 2) that there is competition between AC and SiC for O2, which leads to a slow heating rate and a lack of reducing atmosphere, and this series of reasons makes the process of the iron oxide reduction reaction slower and instead promotes the reaction of generating the ceramic phase.…”

This study provides a novel method to prepare metal-ceramic composites from magnetically selected iron ore using microwave heating. By introducing three different microwave susceptors (Activated Carbon, SiC, and a mixture of Activated Carbon and SiC) during the microwave process, effective control of the ratio of metallic and ceramic phases has been achieved easily. The effects of the three susceptors on the microstructure of the metal-ceramics and the related reaction mechanisms were also investigated in detail. The results show that the metal phase (Fe) and ceramic phase (Fe2SiO4, FeAl2O4) can be maintained, but the metal phase to ceramic phase changed significantly. In particular, the microstructures appeared as well-distributed nanosheet structures with diameters of ~400 nm and thicknesses of ~20 nm when SiC was used as the microwave susceptor.

“…The piezoelectric effect was first discovered by Pierre Curie and Jacques in the 1880s [ 1 ]. This effect describes the conversion of mechanical energy into electrical energy and vice versa [ 2 , 3 ]. Piezoelectric materials are available in natural form and can also be artificially synthesized.…”

“…Quartz, Rochelle salt, and tourmaline are examples of natural piezoelectric materials. Some piezoelectric materials, such as Lead Zirconium Titanate (PZT), Lead Lanthanum Zirconate Titanate (PLZT), Aluminum Nitride (ALN), Zinc Oxide (ZnO), and Polyvinylidene Fluoride (PVDF) are artificially synthesized [ 3 , 4 ]. The piezoelectric property is related to the material’s non-centrosymmetric crystal structure [ 5 ].…”

Polyvinylidene Fluoride (PVDF) is becoming a widely used piezoelectric material because of its flexibility, low cost, light weight, and biocompatibility. Its electronic properties, such as its permittivity, can be affected by material crystal structure variations, which also greatly impact the material’s application. It is known that external stress and electrical fields can alter the crystal structure of piezoelectric material. In this research, we aim to investigate the relationship between the external electrical field and the permittivity property of PVDF material. The basic standard equations, finite element analysis, and experimental measurement are included in this paper. By using sweeping voltages from −25 V to +25 V using an Agilent Technologies B1500A Semiconductor Device Analyzer, an increase in the permittivity of the PVDF material is observed. In this work, the study of the permittivity change under the application of different electrical fields at room temperature is presented, and the application of the electrical field under different temperatures is also studied and presented.
