Simulated results of the piezoelectric device by using COMSOL Multiphysics®: (a) Comparative of simulation and electrical characterization of the maximum open-circuit voltage that can be generated by the piezoelectric generator submitted to a frequency sweep with an acceleration of 0.5 G; (b) A comparison of the maximum power generated in relation to the depth of the piezoelectric material and the load impedance.
