ABSTRACT This is the first study of the significant influence of the 0–3 ceramic / polymer layer on the hydrostatic piezoelectric parameters of novel 2–0–2 relaxor-ferroelectric single crystal / ferroelectric ceramic / polymer composites. Examples of the performance of two 2–0–2 composites based on domain-engineered single crystals are analysed by taking into account the elastic anisotropy of the 0–3 ceramic/polymer layers with changes in the volume fraction of ceramic inclusions and their aspect ratio. The unique feature of the hydrostatic properties of the studied 2–0–2 composites consists in their large values of piezoelectric coefficients $d*h$ ≈ 1 nC/N and $e*h$ ≈ 20 C/m2, squared figure of merit $d*h$$g*h$∼ 10−10 Pa−1, and electromechanical coupling factor $k*h$ ≈ 0.7.

新型 2-0-2 复合材料的显着静水压电响应

摘要 这是首次研究了 0-3 陶瓷/聚合物层对新型 2-0-2 弛豫-铁电单晶/铁电陶瓷/聚合物复合材料的静压压电参数的显着影响。通过考虑 0-3 陶瓷/聚合物层的弹性各向异性以及陶瓷夹杂物的体积分数及其纵横比的变化，分析了基于域工程单晶的两种 2-0-2 复合材料的性能示例. 所研究的 2-0-2 复合材料的流体静力学特性的独特之处在于它们的大压电系数值 $d*h$ ≈ 1 nC/N 和 $e*h$ ≈ 20 C/m2，平方品质因数$d*h$$g*h$∼ 10−10 Pa−1，机电耦合系数 $k*h$ ≈ 0.7。
