    • 摘要: Piezoelectric(PZ)energy has been paid attention to as conventional renewable energy sources including solar,wind,and geothermal power.To address the dilemma of climatic conditions affecting the energy harvesting using Lead Zirconate Titanate(PZT)in pavement,wafer-boxes were used with embedded PZT sensors,since wafer-boxes have the ability to be embedded in the pavement where sensors are protected from any kind of physical damage.This research project was designed to identify which shaped wafer-box produced the most electric voltage and power.Various forms of wafer-box were developed to identify if there was any potential difference in voltage generation due to the structural shapes of the box.Seven different shapes of prototype wafer-boxes were designed utilizing both a 3D printer and 3D Computer Aided Design(CAD).These wafer-boxes were coupled with embedded PZT sensors which were tested in asphalt pavement analyzer(APA)machine under certain load to produce electric voltage.Collected voltage data from the APA wheel load test(WLT)were analyzed using various statistical methods.The statistical analyses results indicated that out of the seven different shaped wafer-boxes,the right-angled triangular shaped box produced the highest average voltage values where’s square shaped wafer-box produced the lowest amount of voltage.Structural properties of a wafer-box in terms of section modulus,area moment of inertia,extreme points,and radius of gyration were also analyzed,and a regression analysis was conducted to identify the reasons of different amounts of voltage produced.These voltage values could be used to calculate the power using power formulas showing relationship between power and voltage values.The outcome helped to identify which shape is most effective to power generation under certain circumstances.The regression analysis results indicated that out of four properties the section modulus is the most influential structural property affecting voltage production.

    • 摘要: The theoretical possibility of the temperature-activation process of the temperature dependence of the dielectric constant of sam-ples of ferroelectric ceramics lead zirconate titanate(PZT)at temperatures below the Curie point is considered.The model takes into account the 180°motion of the domain wall,which is located in the potential well.The values of activation energies(~0.01,0.1,1 eV)were obtained from the experimental dependences of the logarithm of the dielectric constant on the reciprocal tempera-ture.This is associated with three processes:initial vibrations of domain walls;separation of domain walls(DWs)from oxygen vacancies;the motion of DWs as a result of the motion of oxygen vacancies.

    • 摘要: Pb(Zr_(1-x)Ti_(x))O_(3)(PZT)由于具有优异的综合性能而成为应用最广泛的压电陶瓷。之前研究工作证明了与直流极化(DCP)和交流极化(ACP)相比,采用交流极化和直流极化相结合的方法能进一步提高弛豫铁电单晶材料的压电性能。本工作报道了直流极化、交流极化和交流极化+直流极化后PZT-4压电陶瓷的介电性能和压电性能,探究了直流极化、交流极化和交流极化+直流极化的最佳极化条件。在最佳交流极化+直流极化条件下,PZT-4压电陶瓷的压电常数(d_(33))为350 pC/N,相比直流极化(305 pC/N)、交流极化(320 pC/N)分别提高了15%和9%。交流极化后的PZT-4陶瓷样品的应变值(0.08%)高于进行直流极化样品的(应变值0.05%),表明交流极化可以有效提高PZT-4陶瓷的应变值,但是交流极化后应变曲线的滞后增大不利于器件应用,交流极化对硬性压电陶瓷的影响还需要进一步探讨。

    • 摘要: Pb_(0.96)Sr_(0.04)(Zr,Ti)_(0.7)(Zn_(1/3)Nb_(2/3))_(0.3)O_(3)(PZN-PZT)piezoceramics with various Zr/Ti ratios and Li_(2)CO_(3)sintering aid were sintered at 900°C by the solid-state reaction route.The samples with different Zr/Ti ratios were compared according to microstructure,phase structure,piezoelectricity,ferroelectricity,and dielectric relaxation.The Zr/Ti ratio in the PZN-PZT ceramics greatly affects the electrical properties.The Zr/Ti ratio affects the proportion between the rhombohedral and tetragonal phases and also affects the grain size.The PZN-PZT ceramics with the Zr/Ti ratio of 53:47 have the largest grain size and have optimized piezoelectric prop-erties(k_(p)=0.58,d_(33)=540 pC/N,and T_(C)=250°C).The larger the grain size,the lesser the grain boundary,the easier the domain wall motion,and the better the piezoelectric properties.The PZT ceramic with Zr/Ti ratio of 53:47 locates the morphotropic phase boundary(MPB)region which is one of the key factors for the high piezoelectric properties of the PZT.

    • 摘要: 锆钛酸铅(PZT)基压电陶瓷是一类应用非常广泛的功能材料,可应用于水声换能器、压电马达、医疗超声换能器以及声表面波滤波器等.通过改性提高PZT基压电陶瓷的压电性能一直是该领域的研究热点.本工作采用传统固相反应法制备了准同型相界(Morphotropic Phase Boundary,MPB)组分的Sm-0.25PMN-0.75PZT压电陶瓷,并对其微观结构以及宏观性能进行了系统研究.研究结果表明:引入Sm3+可以增强压电陶瓷的局域结构异质性,提升介电响应从而提高压电性能.当Sm3+引入过多时,铁电极化的长程连续性被大面积打断,压电性能下降.本实验中得到的最优组分压电陶瓷性能为:高压电系数d33~824 pC/N,高压电电压常数g33~27.1×10-3 m2/C和相对较高居里温度TC~178°C,电致应变在室温至150°C范围内低于5%,有较好的温度稳定性,是极具应用前景的高性能压电材料.
