Numerical Modeling of a Novel Mesoscale EM Energy Harvesting System Based on Halbach Array

We propose in this paper a numerical modeling based on Finite Element Analysis (FEA) followed by a data post-processing of an EM energy harvester based on Halbach array. The proposed numerical approach was validated with experimental and simulation results from existing work in the bibliography. A parametric study was accomplished to optimize the system and we were able to increase generated voltage from 2 to ~3 V. Thereafter, we investigated the effect of the Halbach array, and we proposed a novel EM system in which we improved the ratio of the active volume to the total volume and obtained an induced voltage of ~10V.
