Nonlinear nonconservative behavior and modeling of piezoelectric energy harvesters including proof mass effects (2012, background): “While the study by Nayfeh and Mook (1979), among many others, details procedures for doing so, a good stability analysis and discussion in the context of a nonlinear harvester can be found in a recent article by Daqaq et al. (2009).”
On the Role of Nonlinearities in Vibratory Energy Harvesting: A Critical Review and Discussion (2014, background): “[65] showed that the region of parametric instability wherein energy can be harvested shrinks as the coupling coefficient, j, of the harvester increases and that there exists an optimal coupling coefficient beyond which the peak power decreases.”
Modeling and analysis of piezoaeroelastic energy harvesters (2012, background): “Energy harvesting through conversion of ambient vibrations to electrical power has been the subject of many studies over the past two decades [1–6].”
Global nonlinear distributed-parameter model of parametrically excited piezoelectric energy harvesters (2012, methodology): “[21] studied energy harvesting using a parametric excitation.”
