Abstract

Magnetoelectric materials made from magnetostrictive and piezoelectric constituents are best suited for selfsensing actuators. The relationship between applied magnetic field (force), tip displacement (deflection) and current output (sensing signal) is necessary for the development of self-sensing actuator systems. The dynamic behavior of the constituent magnetostrictive materials and piezoelectric materials independent of each other are well-understood. The coupled dynamic force-strain-sensing behavior of magnetoelectric materials as selfsensing actuators is largely unexplored and provides the motivation for our work in this area. This paper presents theoretical and experimental analysis of the dynamic behavior of a Metglas/PVDF magnetoelectric laminate composite. Experimental results for the mechanical and electrical behavior of a 15mm × 30mm × 75μm Metglas/PVDF cantilever beam across the frequency spectrum are compared to those predicted by an equation of motion developed using the principle of virtual work and Hamiltonian principle. The theoretically developed model predicts the observed displacement and sensing current within 35% and 20% respectively. A parametric analysis is presented to determine the optimum design parameters of the composite for self-sensing actuation.
