Abstract
The research presents an optimization procedure for the thickness of the active element in a piezoelec-tric energy harvester for the fixed second eigenfrequency to enhance electrical output. The cantilever beam is modelled as a two degree of freedom Bernoulli-Euler element. The optimal design cantilever achieves a 70% efficiency of generated strain compared to the uniform cantilever, with experimental results confirming the mathematical model.
