An application of the global sensitivity analysis on a bistable energy harvester

Résumé

Piezoelectric energy harvesting technologies are being explored by many researchers, due to their high potential to provide clean energy for low consumption devices. It consists of an electromechanical system capable of converting mechanical energy, dissipated in the environment, into electrical energy. Currently, one of the main challenges is to optimize the power harvesting over a wide frequency range and, according to [1], an alternative is the inclusion of non-linearities. Nonlinear systems require rigorous studies and analysis, as they can present chaotic behavior. This work presents an application of a global sensitivity analysis based on the Sobol indices, defined by [2], which consists of a decomposition of the total variation of the model’s output, quantifying the individual and joint effect of each model’s input variability.
