Because most piezoelectric devices have interfaces with fluid in engineering, it is valuable to study the coupled field between fluid and piezoelectric media. As the fundamental problem, the three-dimensional Green’s functions for two point forces and a point charge in the interior of fluid and piezoelectric two-phase materials are derived in this paper. Based on the three-dimensional general solutions which are expressed in harmonic functions, the suitable harmonic functions with undetermined constants are constructed. Then, all the components in the fluid and piezoelectric two-phase materials can be obtained by substituting these harmonic functions into the general solutions. The undetermined constants can be determined by the conditions of compatibility, boundary and equilibrium. Numerical results are presented to shown the characteristics of the electromechanical coupled fields.
