In this paper, a refined, yet simple, model is considered with the aim of providing fast and insightful solutions to the multi-physics problem of piezoelectric energy harvesting by means of laminate cantilevers. The main objective is to retain a simple structural model (Euler-Bernoulli beam), with the inclusion of effects connected to the actual three-dimensional shape of the device. The obtained results are validated by the comparison with 3D analysis carried out with a commercial code, and the procedure is finally applied to the case of a realistic MEMS harvester.

Abstract
In this paper, a refined, yet simple, model is considered with the aim of providing fast and insightful solutions to the multi-physics problem of piezoelectric energy harvesting by means of laminate cantilevers. The main objective is to retain a simple structural model (Euler-Bernoulli beam), with the inclusion of effects connected to the actual three-dimensional shape of the device. The obtained results are validated by the comparison with 3D analysis carried out with a commercial code, and the procedure is finally applied to the case of a realistic MEMS harvester.File in questo prodotto:
