Abstract
The 2-2-0 single-domain 0.67Pb(Mg1/3Nb2/3)O3-0.33PbTiO3 crystal/porous polyurethane composite is studied in which the orientation of the spontaneous polarisation vector Ps of crystal, its volume fraction and the volume fraction and shape of pores in polymer are varied to attain maxima (minima) of effective hydrostatic piezoelectric coefficients dhâ and ghâ, squared figure of merit dhâghâ and electromechanical coupling factor khâ. This paper describes an effect of the Ps orientation and the shape of pores on the hydrostatic piezoelectric response of this composite. Advantages caused by large values of dhâ, ghâ, dhâghâ, and khâ of the studied composite are discussed.
