We examine an energy harvesting system of two magnetopiezoelastic oscillators coupled by electric circuit and driven by harmonic excitation.We focus on the effects of synchronization and escape from a single potential well.In the system with relative mistuning in the stiffness of the harvesting oscillators,we show the dependence of the voltage output for different excitation frequencies.
