Investigation on the factors influencing the performance of piezoelectric energy harvester

In this study, the authors devised a promising method to harvest the clean power from vehicle vibrations. The authors tested the electrical response of stacked piezoelectric units at different temperatures and loadings by using indoor laboratory tests. It is also discovered that ambient temperature has a great influence on the piezoelectric power generation. The generated electric energy of piezoelectric unit increased with increase in the loading and their relationship follow the cubic polynomial. It is demonstrated that there is a linear correlation between the open-circuit voltage and the amount of charge generated of the piezoelectric unit. The output energy increases with an increase in the frequency and the load.
