On the Role of Nonlinearities in Vibratory Energy Harvesting: A Critical Review and Discussion
TL;DR: In this article, the authors highlight the role of nonlinearities in the transduction of energy harvesters under different types of excitations and investigate the conditions, in terms of excitation nature and potential shape, under which such non-linearities can be beneficial for energy harvesting.

Increasing the power of piezoelectric energy harvesters by magnetic stiffening
TL;DR: In this paper, the attraction force between two permanent magnets is used to add stiffness to the system, which counters the effect of the tip mass on the efficient operation frequency, and five set-ups incorporating piezoelectric bimorph cantilevers of the same type in different mechanical configurations are compared theoretically and experimentally to investigate the feasibility of this principle.

Energy harvesting from the nonlinear oscillations of magnetic levitation
Brian P. Mann,Neil D. Sims +1 more
TL;DR: In this article, the authors investigated the design and analysis of a novel energy harvesting device that uses magnetic levitation to produce an oscillator with a tunable resonance and derived the governing equations for the mechanical and electrical domains to show the designed system reduces to the form of a Duffing oscillator under both static and dynamic loads.

On energy harvesting from ambient vibration
TL;DR: In this article, an elastically mounted magnetic seismic mass moving past a coil, considered previously by several authors, is analyzed in detail. And the overall damping coefficient (part of which is mechanical) is associated with the harvesting and dissipation of energy and also the transfer of energy from the vibrating base into the system.

Energy Scavenging for Wireless Sensor Networks: with Special Focus on Vibrations
TL;DR: In this paper, the authors present an analytical model of a piezoelectric generator with an inplane gap closing converter for V2E power conversion, which is based on the basic dynamic model of the generator's bimorph mounted as a cantilever.
