Abstract
Effective electromechanical properties, figures of merit andrelated parameters are firstly studied within the framework of proposedmodels of piezoactive composites `ferroelectric ceramic-polymer'(connectivity 1-1) and `ferroelectric ceramic-porous polymer'(connectivity 1-0-1). The effect of the shape of the pores on the piezoelectriccoefficients, their anisotropy, electromechanical coupling factors, figures of merit,etc in 1-0-1 composites is analysed. The calculatedconcentration dependences of the piezoelectric coefficients and otherparameters as well as the piezoelectric anisotropy of 1-1 and 1-0-1composites have no analogy to known data on two- and three-componentcomposites on the basis of ferroelectric ceramics.
