Analysis of Output Performance for Piezoelectric Double Mode Energy Harvester

Abstract:

The output performance of piezoelectric double mode energy harvester is studied, which is provided with a dynamic magnifier consisting of a spring-mass system placed between the piezoelectric element and the moving base. The theory governing the operation of the energy harvester with dynamic magnifier is developed using the Lagrangian dynamic approach, Numerical examples are presented to illustrate the output performance of the energy harvester in comparison with the conventional energy harvester, the results show that with proper selection of the design parameters of the magnifier, the harvested power can be dramatically enhanced and the effective bandwidth of the harvester can be improved.
