| description | This study investigates the performance of asymmetric bistable energy harvesters with nonlinear piezoelectric coupling, focusing on the impact of parametric variability on system reliability. Global sensitivity analysis using Sobol indices identifies critical parameters influencing harvested power, providing insights for the robust design of nonlinear harvesters. To address uncertainties in system parameters, we employ a probabilistic framework incorporating Polynomial Chaos Expansion (PCE) and probabilistic maps. This approach, leveraging the maximum entropy principle, models and propagates uncertainties to visualize their effects on power output. Results show that excitation frequency, amplitude, asymmetric terms, and piezoelectric coupling properties are critical factors, with their importance varying across dynamic stability regimes. Our findings highlight the need to account for joint parameter variability to enhance energy harvesting system efficiency and reliability. |
