Magnetoelectric effects analysis of a hybrid piezoelectric cantilever

Abstract

This paper presents a hybrid energy harvester to harvest dual piezoelectricity and piezomagnetism using piezoelectromagnetic transduction. Multilayered configuration is used to design the proposed harvester, i.e., the cantilever. Silicon, Lead Zirconate Titanate (PZT-5H) and Stainless Steel 405 Annealed are used to configure the cantilever for 2 different cases. For both cases, the geometry is set to (10×1×0.3) mm3 device size. Several Eigenfrequencies are applied to evaluate the deformations of the cantilever. In addition, the influence of Eigenfrequencies on total cantilever displacements and elastic strain energy density are observed. From the findings, it is evident that, vertical displacement of the cantilever can be as high as 3 mm for both cases. However, case 1 and 2 has significant disagreement in elastic strain energy density which are approximately 0.2 and 2.5 J/m3 respectively. Hence, multilayered configuration is more beneficial in terms of energy penetration and significantly distinguished.
