In recent years, vibration energy harvesting is receiving a considerable amount of interest among the researchers. With the global concern on energy issues, this lead to an increase in the study of vibration based energy harvesting and use it as an alternative source of energy. This paper presents an idea on harvesting energy using the mass spring absorber system attached with a transducer. The aim is to investigate the effect of damping, mass, stiffness and bandwidth towards energy harvesting system performance. The stiffness, mass, damping and bandwidth will be the parameter to be studied. This will enable author to investigate the behavior of each parameter towards the system and how its effect the power output. Simple mechanical absorber system will be modeled based on the undamped, damped and forced vibration second degree of freedom equation of motion. Based on the mathematical equation derived, the stiffness, mass, damping and bandwidth is simulated and how its affect the system is observed. The results shows that amplitude will increase as damping is decreases, while amplitude will be decrease as damping higher. The optimum mass ratio (M2/M1) of the system is between 5%-10%. The acceptable range of bandwidth ratio is from 5% to 30%, as higher ratio will lead to less power output from the system.
