On the Role of Nonlinearities in Vibratory Energy Harvesting: A Critical Review and Discussion (2014, background): “As will be seen later in this manuscript, for a resistive load, even when j(2) is nonnegligible, its effect on the dynamics of the oscillator can be captured by a shift in the oscillation frequency and additional linear damping [32,40].”
A Hybrid Nonlinear Vibration Energy Harvester (2017, methodology): “Combining piezoelectric and electromagnetic energy harvesting mechanisms, a hybrid nonlinear system was studied by Karami and Inman [24] who introduced a unified model to predict the system behavior.”
Piezoelectric energy harvesting from concurrent vortex-induced vibrations and base excitations (2014, methodology): “For the same purpose, different techniques have been employed, such as beam geometry [10,11], multimodal systems [12,13], magnetic coupling [14–16], and bistable configurations [17–19].”
