Purpose: In this article, the energy harvesting characteristics of functionally graded magneto-electro-elastic (FGMEE) cantilever beam under transverse vibration have been discussed using an analytical method. Methods: The coupled governing differential equations are derived using the integration of lumped parameter single degree of freedom model (SDOF), Gauss's law, Newton's law and Faraday's law. Based on the modified power law, two forms of functional gradation such as 'B' rich bottom and 'F' rich bottom are incorporated into the material property equations and considered for evaluation. The proposed energy harvester (EH) system consists of the FGMEE layer mounted on the isotropic substrate layer. An electrode circuit at one end of the beam is used to extract the electric voltage produced, while a coil at the other end of the beam is used to harvest the magnetic potential produced. Results: The numerical examples are presented to analyse the effect of main parameters such as gradient index, functionally graded pattern, number of turns, and resistance on the system's output response. Also, the effect of coupling associated with energy harvesting capabilities is discussed. The results of this study reveal that both material and system parameters play a predominant role in harvesting the energy from the vibrations induced. © 2022, Krishtel eMaging Solutions Private Limited.
