Modeling and analysis of piezoelectric vibrating generator of cantilever

摘要：

In order to improve greatly power capacity of cantilever beam piezoelectric generator, output voltage, electric charge and energy of unimorph, bimorph series connection and parallel connection is analyzed by theory models. It can be seen from analytic results that the larger output voltage and electric energy would be obtained if length is increased and width is decreased under the exterior stimulation circumstances. At the same time, bimorph series connection piezoelectric beam should be chosen preferentially.
