Resonant manifestation of intrinsic nonlinearity within electroelastic micropower generators
Abstract
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 despite geometrically linear motion. Fourth
order elastic and electroelastic tensor values for PZT-5A are identified following
methods recently published concerning a PZT-5H bimorph. A response trend indicative
of a nonlinear dissipative mechanism is discussed as well as the inadequacy of linear
modeling. The PZT-5A bimorph exhibits an increased softening frequency response in
comparison to PZT-5H. The results contained herein are also applicable to electroelastic
sensor and actuator technologies. © 2010 American Institute of Physics.
