Rotating machinery is widely used in the industrial plant, for example, power plant, chemical plant, mass-production plant and so on. In order to ensure safety operation of the rotating machinery, vibration condition monitoring of the machinery can play a crucial role. In this study, the vibration energy harvester of the piezoelectric bimorph cantilever type was proposed for vibration condition monitoring applications of rotating machinery. Proposed energy harvester consisted of Macro-Fiber Composite (MFC) actuator which is flexible and durable piezocomposite type actuator. This study evaluates the power generation performance of proposed energy harvester via both numerical simulation and experiment when subjected to sinusoidal mechanical vibration.
