Energy Harvesting from Highly Unsteady Fluid Flows using Piezoelectric Materials (2010, methodology): “1In case of a piezoelectric generator, an accurate modeling of coupling of electrical and mechanical domains is required to calculate the correct values of power output as suggested by Erturk and Inman (2008a).”
Piezoelectric Energy Harvesting Solutions (2014, background): “Inertial generators can be described as a second order mass-spring-damper system [29,43–45], along with a piezoelectric element connected parallel to the damper [28] (Figure 6).”
An electromechanical finite element model for piezoelectric energy harvester plates (2009, background): “Recently, certain issues observed in some of these lumped parameter and distributed parameter piezoelectric energy harvester models have been clarified in the literature [23].”
Impedance Modeling and Analysis for Piezoelectric Energy Harvesting Systems (2012, methodology): “The dynamics of a PEH system with real harvesting interface circuits, e.g., SEH, P-SSHI, or S-SSHI would be more complicated than what was presented in Williams and Yates’s model, and might also be different from what Erturk and Inman have shown with the RSD equivalence for the PEH system.”
Toward Broadband Vibration-based Energy Harvesting (2010, background): “For a piezoelectric generator, the damping caused by piezoelectricity cannot be modeled as a viscous damper (Erturk and Inman, 2008b) and Eqn.”
Array of piezoelectric energy harvesting by the equivalent impedance approach (2012, background): “Vibration-based piezoelectric energy harvesting has received significant attention recently due to the potential of high energy density capable of powering remote sensor nodes [3, 5–7, 16, 34, 42].”
An experimentally validated bimorph cantilever model for piezoelectric energy harvesting from base excitations (2009, background): “Thus, highly different modeling approaches have appeared in the literature during the past five years and some of them might be misleading due to weak mathematical assumptions involved [26].”
Frequency Self-tuning Scheme for Broadband Vibration Energy Harvesting (2010, methodology): “…by a rough but effective electromechanically coupled single degree of freedom (SDOF) model such as a spring-mass-damper system (Badel et al., 2007; Erturk and Inman, 2008): M €uþ C _uþ KEu ¼ 1Ma V I ¼ _u C0 _V ð3Þ where u, a, V, and I refer to the beam deflection, base acceleration, piezoelectric…”
Piezoaeroelastic Modeling and Analysis of a Generator Wing with Continuous and Segmented Electrodes (2010, methodology): “More recently, analytical distributed parameter solutions for unimorph and bimorph piezoelectric energy harvester configurations with closedform expressions have been presented (Erturk and Inman, 2008b, 2009).”
An application of stochastic resonance for energy harvesting in a bistable vibrating system (2014, background): “One of the most important factors that can generally affect harvesting efficiency is the damping ratio of the system [46,47].”
A coupled piezoelectric–electromagnetic energy harvesting technique for achieving increased power output through damping matching (2009, background): “A simple single degree-of-freedom (lumped parameter) model is chosen here for simplicity (the limitations of such an approach for piezoelectric energy harvesting has recently been discussed in the literature [27, 28]).”
Energy harvesting performance of piezoelectric electrospun polymer fibers and polymer/ceramic composites (2013, background): “On the other hand, the electromechanical system can be modeled by a coupled spring-mass-damper system, [34] and in the case of the BaTiO3/P(VDF-TrFE) the ceramic nanoparticles acts as a defect for the fibers (figure 4), contributing for the increase of the damping of the composite fibers and consequ”
An energy harvester using piezoelectric cantilever beams undergoing coupled bending–torsion vibrations (2011, background): “Researchers have proposed various mathematical models for beam energy harvesters [4, 7–10, 13]: lumped-parameter and distributed-parameter models.”
