This article analyzes the performance of a piezoelectric drum transducer in the flexural mode for scavenging ambient vibration energy. We have derived an analytical solution from the governing equations of piezoelectricity that shows the role of each of the physical parameters in determining the performance of the piezoelectric energy harvester, measured by the output power density and the power efficiency. Numerical results indicate the considerably enhanced performances by adjusting the physical and geometrical parameters of the scavenging structure.
