Abstract: This paper studies a two degree of freedom electromagnetic vibration energy harvesting system with a magnet arrangement of the Halbach array. A theoretical analysis and computational simulation of the system were established through frequency response analysis and time domain integration of the system motion equations using the Matlab Simulink software. The results of the theoretical analysis and simulation models were compared with the results of a series of experiments, verifying the analysis approach.

Keywords: electromagnetic; Halbach array; two degrees of freedom; 2DOF; vibration energy harvesting; coil profile; magnetic field intensity; electro-mechanical coupling; power output.
