Abstract
The work deals with nonlinear piezoelectric energy harvesting device dynamics, intending to map configuration of parameters able to provide chaotic and non-chaotic response behaviour. 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.
