Abstract :
We analyze the behavior of a model piezoelectric power harvester near resonance. Nonlinear effects of large deformations due to resonance are considered using a cubic theory of the displacement gradient. Results on the output current and power are presented, which exhibit multivaluedness and jump phenomena.
