In an era that highly advocates for renewable and sustainable energy, vibration energy harvesting has taken attention of many due to the potential in contributing to so many shortcomings of miscellany applications and devices. The availability of vibration from natural and man-made resources have elevated it to the peak of interest of many studies over the years. Over these years of study and research, various identifications and implementations of methods were done. However, there are still many scopes of improvement in the area. And as the world now progresses more towards sustainable energy ever than before, piezoelectric energy harvesting system among the vibration energy harvesting systems secures a permanent interest to shape up the idea of energy harvesting for application and devices that require small fraction of power. The purpose of the research study is to configure a cantilever beam with a tip mass on top of it to deal with the current shortcoming of piezoelectric energy harvester outputs, which is a narrow resonance frequency. The goal is to identify the factors that may contribute to the enhancement of the outcome bandwidth. The focus of the study is not to aim for a higher magnitude of peak values, instead a wider bandwidth of frequency with stable values is the desired outcome of the study. COMSOL Multiphysics would be used to simulate the cantilever beam upon changing the configuration of the system, e.g., size, shape, and the material of the tip mass. Upon conclusive discussion on the enhancement of the system, a nonlinear approach would be taken by introducing magnets into the system. Upon inspecting and achieving the results produced by a magnetic spectrum in the system, a design and simulation would be performed to identify the results achieved by a broadband harvesting system.
