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*_hg*_h∼ 10⁻¹⁰ Pa⁻¹, and electromechanical coupling factor k*_h ≈ 0.7.
