Abstract
Vibration-based energy harvesting had been extensively investigated
by several researchers over the last decade. The use of piezoelectricity is known for its
mechanical vibration-to-electricity conversion. The piezoelectric energy harvesters
(PEHs) efficiency is dependent on the cantilever geomtry and the vibration source
frequency. In this paper, cantilevered beams with piezoelectric layers of PZT-5A
material are employed as piezoelectric energy harvesters. Three kinds of PEH
cantilever beams were constructed which are the unimorph, bimorph and bimorph
without load. The simulation of these three beams were made on ANSYS software.
This was meant for the study of the performance for each of the PEH cantilever beams
and they had proven distinctions among them. Modal analysis and Harmonic Response
analysis were setup and run for the three types of beams and the results were validated.
The outcome of the simulation analysis was generated and interpreted graphically
which shows the model deformation, voltage and the frequency response for all the
beams with same weight of load and dimensions.
