On the efficiency of piezoelectric energy harvesters (2017, unknown): “To broaden the frequency bandwidth, researchers have introduced nonlinear vibration into energy harvesting systems [15,43,64,65] It is unclear whether the phase difference of these nonlinear systems will match the linear ones.”
Rotational energy harvesting using bi-stability and frequency up-conversion for low-power sensing applications: Theoretical modelling and experimental validation (2019, background): “Double potential wells are normally introduced in these devices using pre-loaded forces [24], magnetic levitation [25] or even residual stress generated by the fabrication process [26].”
Nonlinear nonconservative behavior and modeling of piezoelectric energy harvesters including proof mass effects (2012, methodology): “Following Masana and Daqaq (2011), we order the coupling parameter u in the mechanical dynamics to appear at higher-order perturbation corrections but to an order of zero in the electrical network.”
On the Role of Nonlinearities in Vibratory Energy Harvesting: A Critical Review and Discussion (2014, methodology): “In another demonstration, Masana and Daqaq [86] noticed theoretically and experimentally that the superharmonic frequency bands can activate large-amplitude motions at much lower excitation amplitudes if the VEH has a bistable potential well.”
Piezoelectric energy harvesting from vortex-induced vibrations of circular cylinder (2013, background): “To date, most of energy harvesting from mechanical vibrations has concentrated on exploiting base excitations [12–16].”
Design and performance of variable-shaped piezoelectric energy harvesters (2014, background): “Masana and Daqaq (2011) proposed an axially loaded piezoelectric clamped–clamped beam in order to tune the natural frequency to the dominant excitation frequency.”
A Hybrid Nonlinear Vibration Energy Harvester (2017, methodology): “To increase the bandwidth, several methods introduced nonlinearities into the energy harvesting system [2] such as using stoppers to realize a spring hardening effect [3–5] and using axial static preload to stiffen or soften the structure [6,7].”
