Abstract

Behaviour of the effective hydrostatic piezoelectric coefficients dh* and gh*, squared figure of merit (Qh*)2 and electromechanical coupling factor kh* has been analysed for the 1-3-type relaxor-ferroelectric single crystal/auxetic polymer composites on changing microgeometry and properties of the porous matrix. A correlation between max Xh*/ Xh(1) and a ratio of elastic compliances of the porous matrix s(33)2/s(11)2 has been stated for a composite based on the single crystal poled along [001] of the perovskite unit cell, where denotes the hydrostatic parameter of the single crystal. Advantages of the novel 1-3-type composites are discussed.
