The analytical formula of the magnetoelectric coefficient of the three-phase composite was given by the Green’s function method, and the magneto-electric coefficient of terfenol D PZT PVDF three-phase particle composite was calculated. The calculation result is given The relationship between the magnetic and electrical properties of composite materials and the microstructure of the materials, including the magnetic and electrical properties of the three-phase composite materials with components, the aspect ratio of the particles, the polarization direction of PZT particles and the changing trend of the external magnetic field may be Experimental design to provide reference and guidance through the rational design of the performance of three-phase magnetoelectric composite can reach hundreds of mV A. As a new magnetoelectric composite, three-phase particulate composite is expected to become a new type of high performance and easy preparation Magnetic material
