Finite Element Modeling of a Cantilever Beam Bonded By Piezoelectric Material with Additional Single Degree of Freedom Elastic System at Fixed End for Energy Harvesting Application

Vibration based energy harvesting has received growing attention over the last decade. The research motivation in this field is due to the reduced power requirement of small electronic devices, such as the wireless sensor networks used in passive and active monitoring applications. The ultimate goal in this research field is to supply power to such small electronic devices by using the vibrational energy available in their environment. Because of their electromechanical coupling characteristics, piezoelectric material can also be used for vibration control. The paper aims “to complete finite element analysis of a cantilever beam having PZT5A patch with SDOF system for constant input amplitude�. This paper highlights on the energy harvesting of piezoelectric material (PZT5A) by using single degree of freedom system to cantilever beam.
