On Energy Harvesting Characteristics of Cymbal Transducer

Abstract:

The energy-generating capability of a cymbal transducer was studied in order to supply the power of low-consumption electric products. An analytical model of the cymbal transducer was established by the hydrostatic piezoelectric constant method. The relation between the material of metal cap as well as the structure of transducer and energy generation were analyzed by numerical simulation. The simulation validation was done by the element software ANSYS. The results of the study show that, in the same force, the materials of metal cap, the radius of cavity bottom, and the thickness of metal cap have bigger influence on the voltage outputted, the radius of cavity top have less influence on the voltage outputted.
