Nonlinear piezoelectricity in electroelastic energy harvesters: Modeling and experimental identification

Stanton, SC; Erturk, A; Mann, BP; Inman, DJ (Journal of Applied Physics, 2010-10-01)

We propose and experimentally validate a first-principles based model for the nonlinear piezoelectric response of an electroelastic energy harvester. The analysis herein highlights the importance of modeling inherent ...
Resonant manifestation of intrinsic nonlinearity within electroelastic micropower generators

Stanton, SC; Erturk, A; Mann, BP; Inman, DJ (Applied Physics Letters, 2010-12-20)

This letter investigates the nonlinear response of a bimorph energy harvester comprised of lead zirconate titanate (PZT-5A) laminates. For near resonant excitations, we demonstrate significant intrinsic nonlinear behavior ...
