| An autonomous system of energy supplier to low power devices or wireless sensors is one of the most important motivations for energy harvesting based on ambient mechanical vibrations. In traditional approach, harvesters were based on a linear mechanical resonator combined with an electro-mechanical transducer working in the resonance region, i.e. in a relatively small range of frequencies. Here, we study a frequency broadband nonlinear resonator with impact characteristics with the aim of increasing the range of operativity of the system. The excitations are modeled by kinematic forcing possessing periodic and stochastic components, motivated by realistic ambient conditions. We show how the noise component of the excitation influences the stability of the solution. |
