Description
Summary:Piezoelectric material is used as an active material to convert vibration energy into electrical output and so called piezoelectric energy harvesting. The harvester's dynamic model depends on several parameters such as physical dimensions, geometrical structure, mechanical and electrical properties of the piezoelectric material. The development of theoretical model for analysis and simulation is a complex task whereas complete information about these parameters is not available from the manufacturer's datasheet. In this paper, the dynamic model parameters are identified experimentally to reduce the modeling effort and to develop easily the equivalent circuit for the energy harvester (Volture, V21BL). The validation is achieved by comparing the estimated power outputs using simulation model with the real time measured values. The obtained results affirmed the potential of the adopted approach for modeling and simulation.
