Abstract

The active electromagnetic spring (AES) is a novel architecture for vibration energy harvesting (VEH). This paper proposes the design and simulation of an AES using POISSON/SUPERFISH software. The mechanism consists of a single primary coil and secondary coils wound around a dielectric tube. A hollow ferromagnetic cylinder (HFC) moves freely inside the tube, positioned in the air gap between the coils, perpendicular to the HFC's movement. The simulation results are used to analyze the effects of coil ratio on the performance of the AES through electromagnetic field analysis, demonstrating efficient energy harvesting capabilities around the equilibrium point.
