Improvement in operating characteristics of piezoelectric materials, one of the most extensively used dielectric materials, is a major focus of research among materials scientists. Present work puts forward, a novel approach for achieving enhanced piezoelectricity in ferroelectric materials by manipulating electrode placement during poling. Three unique poling configurations, abbreviated as PC1, PC2, and PC3 are developed for exploiting the dependence of effective piezoelectric properties on spatially varying poling direction. Finite element method based numerical simulations are performed to evaluate the electric field distribution, poling direction, and their effect on effective piezoelectric coupling coefficients of PMN–0.35PT (Pb(Mg_1/3Nb_2/3)O₃–0.35PbTiO₃) piezoelectric ceramic. A two-phase solution process is developed to evaluate the local orientation of dipoles for each poling configuration and subsequently computing effective piezoelectric properties of the material in an average sense. Parametric studies are carried out to analyze the effect of aspect ratio R of sample and electrode to sample length ratio, r on effective piezoelectric properties. PC1 yields an increase of up to 135% in the magnitude of the transverse coupling coefficient \(({e}_{31}^{eff})\) and an 8% increase in effective longitudinal coupling coefficient \(({e}_{33}^{eff})\) while PC2 is observed to exhibit a maximum enhancement of 164% in the magnitude of \({e}_{31}^{eff}\) and 11.2% in the magnitude of \({e}_{33}^{eff}\). PC3, presented as a special case, yields zero values of piezoelectric coefficients in an average sense but can result in a highly elevated net output for bending applications, owing to favorable spatial variation in stresses and associated piezoelectric coefficients.

压电材料（使用最广泛的介电材料之一）的工作特性的改善是材料科学家研究的主要重点。当前工作提出了一种新颖的方法，该方法通过操纵极化过程中的电极放置来实现铁电材料中增强的压电性。开发了三种独特的极化配置，分别缩写为PC1，PC2和PC3，以利用有效压电特性对空间变化极化方向的依赖性。进行了基于有限元方法的数值模拟，以评估电场分布，极化方向及其对PMN–0.35PT（Pb（Mg _1/3 Nb _2/3）O ₃ –0.35PbTiO的有效压电耦合系数的影响₃）压电陶瓷。开发了一种两相溶液法，以评估每种极化配置的偶极子的局部取向，并随后以平均意义计算材料的有效压电性能。进行了参数研究，以分析样品的纵横比R和电极与样品的长度比r对有效压电性能的影响。PC1的横向耦合系数\（（{e} _ {31} ^ {eff}）\）的幅度最多增加135％，有效纵向耦合系数\（（{e} _ {33} ^ {eff}）\），而观察到PC2的\（{e} _ {31} ^ {eff} \）幅度最大增强了164％和\（{e} _ {33} ^ {eff} \）大小的11.2％。作为一种特殊情况，PC3在平均意义上产生零个压电系数值，但由于应力和相关压电系数的有利空间变化，在弯曲应用中可导致很高的净输出。
