Nonlinear Modelling of T-shaped Piezoelectric Device for Structural Health Monitoring and Fluid Energy Harvesting

Abstract

This contribution focuses on modeling the dynamic behavior of T-shaped piezoelectric energy harvester devices. Nonlinearities arising from different aspects, such as material and geometrical effects, are taken into account. Classical reduced-order modeling approaches have been enhanced by including effects of large deformations, yielding to effective circuit representations that allows for an intuitive insight in the energy transduction processes characterizing the considered class of devices.
