Piezoelectric Energy Harvesting

open access: yes, 2016
This chapter reports on the modeling of electromechanically coupled beams with uniform and varying cross-sectional areas for energy harvesting. The governing equations are formulated by using the Rayleigh-Ritz method and Euler-Bernoulli assumptions. A resistive electrical load is considered in the electrical domain.
