Analytical Modeling of a novel energy harvesting system withsimultaneous use as an electrical actuator system

This paper introduces a novel harvester to store the electrical power, which comes from the power ofexternal applied electrical voltage. The coupled magneto-electro-mechanical (MeM) governingdifferential equations of the MEE energy harvesting system are derived for a harmonic external appliedelectrical voltage in the transversal direction based on Euler-Bernoulli theory, Gaussian law, and Faradaylaw. The results show that the single-layer unimorph configuration is the best choice for storing moreoverall power. Furthermore, the most optimal parameters of the energy-harvesting circuit for extractingthe maximum energy from the various configurations have been determined.
