Design of Piezoelectric Energy Harvesting Systems: A Topology Optimization Approach Based on Multilayer Plates and Shells (2009, background): “The first problem is a cantilever beam harvester (Erturk and Inman, 2008b, c, 2009; Erturk et al., 2009) and the second problem a piezoelectric circular plate (Kim et al., 2005a, b).”
Placement and dimension optimization of shunted piezoelectric patches for vibration reduction (2012, background): “This is especially the case for modes 2 and 3, for which, qualitatively speaking, the optimization process maximizes the slope difference at the patch’s ends as well as avoids the presence of an inflection point on the patch coverage length, which would reduce the coupling factor by a charge cancela”
Power extraction from aeroelastic limit cycle oscillations (2011, background): “A relevant discussion of this issue can be found in Erturk et al. (2009).”
Beam Shape Optimization for Power Harvesting (2010, background): “In other work (Erturk et al., 2009b), researchers have looked into alternative electrode geometries that can operate in higher modes without electrical cancellation.”
An experimentally validated bimorph cantilever model for piezoelectric energy harvesting from base excitations (2009, background): “(22) The forward coupling term κr has important consequences as discussed by Erturk et al [27, 32] extensively.”
Piezoaeroelastic Modeling and Analysis of a Generator Wing with Continuous and Segmented Electrodes (2010, background): “In practice, one might need to use diodes to avoid such cancellations (Erturk et al., 2009b).”
Underwater thrust and power generation using flexible piezoelectric composites: an experimental investigation toward self-powered swimmer-sensor platforms (2011, background): “7 Hz) has a strain node near the root [44], resulting in significant reduction of the power output around the second mode due to continuous electrodes.”
