Abstract

This paper considers effective electromechanical properties of the relaxor-ferroelectric crystal/polymer composite with 2-2 connectivity. A single-domain 0.67Pb(Mg1/3Nb2/3)O30.33PbTiO3 crystal/polymer composite is proposed in which the polarisation vectors of components are tailored to optimise the electromechanical coupling factors k*3j and k*h. A strong correlation between the hydrostatic electromechanical coupling factor k*h and the hydrostatic piezoelectric coefficient d*h is observed near min k*h and max k*h. Examples of the condition k*31=k*32 are also considered. The specific advantages and potential of the 2-2 composite in terms of its considerable d*h and k*h values are discussed in connection with the studied orientation effect.
