Development of a Cantilever Beam Generator Employing Vibration Energy Harvestin

This paper details the development of a generator based upon a cantilever beam inertial mass system which harvests energy from ambient environmental vibrations. The paper compares the predicted results from Finite Element Analysis (FEA) of the mechanical behaviour and magnetic field simulations and experimental results from a generator. Several design changes were implemented to maximise the conversion of magnetic energy into generated power and a maximum power output of 17.8?W was achieved at a resonant frequency of 56.6Hz and an applied acceleration of 60mg (g = 9.81ms-2).
