Exploring the behavior of a bistable energy harvester via global sensitivity analysis

Résumé

A bistable energy harvester presents a rich and complex dynamic behavior due to high sensitivity to the input parameters. The uncertainties arising from the environmental and manufacturing process can significantly affect the energy generation process and, ultimately, the harvester's performance. Understanding how uncertain parameters and excitation variability affect the harvester response is a nontrivial task and can be a preliminary step for uncertainty quantification and optimization problems. In this sense, this study evaluates, via a variance-based global sensitivity analysis technique known as Sobol' indices. These system parameters influence the power recovered from a bistable vibratory energy harvester, such as which parameter most affects the system response.
