Improvements in energy harvesting capabilities of beams: based on displacement PZT and beam shape

The aim of this study is to prove the effect of the displacement PZT and the beam shape on the first ten eigen frequency modes. In this regards, two different beam shapes and three different displacement PZT are considered to investigate the electric potential voltageoutput of the beam. The proposed model is created based on the linear mechanical electrical constitutive law of thepiezoelectric material. It should be noted that the electric potential voltage output is an important component in theenergy harvester system. Thus, the finite element analysis software (ABAQUS) is applied to determine electric potential voltage output. The presented PZT is modeled as a three-dimensional solid adhering to the beam. Another aims of this study is to survey the timedependent analysis. The results show that, the displacement PZT hugely affects on electrical potential output of piezoelectric. In addition, the displacement PZT dosent has high effect on the natural frequencys
