Broadband tristable energy harvester: Modeling and experiment verification (2014, background): “As a result, the intensive investigation of vibration energy harvesters with monostable [15–19] and bistable [20–29] nonlinear characteristics has been carried out to improve the energy conversion efficiency over a wide range of operating frequencies.”
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.”
M-shaped asymmetric nonlinear oscillator for broadband vibration energy harvesting: Harmonic balance analysis and experimental validation (2014, methodology): “Random excitation of monostable Duffing oscillators was theoretically investigated by Daqaq [28] and Green et al.”
The benefits of Duffing-type nonlinearities and electrical optimisation of a mono-stable energy harvester under white Gaussian excitations (2012, methodology): “This led to a significant body of work which focused on analysising the response of energy harvesters to random excitations ([7, 8, 9, 10, 11]) something which will also be the focus of this paper.”
Improving functionality of vibration energy harvesters using magnets (2012, background): “Daqaq (2010) claimed that under white or colored Gaussian excitation environment, the hardening-type nonlinearity failed to improve and even reduced the output power as compared to the typical linear harvesters.”
