摘要：

In this paper a line of proprietary porous piezoelectric ceramics with 3-0 / 3-3 connectivity types manufactured by Ultrashape Ltd. were systematically studied. Complex sets of elastic, dielectric and piezoelectric coefficients of the porous piezoelectric ceramics were measured by ultrasonic and impedance spectroscopy methods using Piezoelectric Resonance Analysis (PRAP) software. Finite element modeling of effective constants of the porous piezoelectric ceramics was performed using ANSYS software package. Critical comparison of numerical FEM calculations with the results of various approximated formulas, unit cell models and experimental data for different porous piezoelectric ceramics was carried out.
