Zusammenfassung:	The magnetoelectric behavior of a dual-phase dimensionally graded magnetostrictive-piezoelectric composite is modeled in this article. The cantilever is formed by piezoelectric macro-fiber composite bonded to a Ni cantilever. Theoretical estimates show a large magnetoelectric voltage coefficient of 100V/(cmOe) at electromechanical resonance frequency. An additive effect was realized when an acceleration and magnetic field was applied to the structure simultaneously. Applied magnetic field of 10Oe and shaker acceleration of 0.02g induce the approximately equal output voltage of 20–35V.
