Finite Element Modeling of Magnetoelectric Energy Transducers with Interdigitated Electrodes
Résumé
This paper proposes a 2D FEM multiphysics modeling to investigate the behaviour of a magnetoelectric material with interdigitated electrodes (IDE) as an energy transducer. A direct approximation is used to combine the IDE with an array of push-pull piezoelectric elements in which the longitudinal mode is imposed. The internal impedance is determined using a numerical method thought the coupling of the field and circuit equations. The simulation results allow estimating the optimal configuration that maximizes the deliverable output power.
