This work deals with the dynamics of a nonlinear piezoelectric energy harvesting device, intending to map configuration of parameters able to provide chaotic and non-chaotic response behavior. The dynamics in explored changing forcing amplitude and excitation frequency. Bifurcation diagrams and basins of attraction are computed, and their analysis allow to identify regions of chaotic and regular dynamics.
