“…The progress and research topics on vibration energy harvesting are summarized in several comprehensive review papers, such as vibration energy harvesting from human motion and machine operation in [4,5], nonlinear mechanisms for broadband energy harvesting in [6,7] and functional materials for energy conversion in [8]. However, as another type of kinetic energy, rotational energy is less investigated and harnessed for power supply, but has unique dynamics that would be beneficial to some applications, including tire pressure sensing [9,10], condition monitoring of rotating machines [11,12] and fluid flow energy harvesting using miniature turbines [13].…”

“…Among these energy resources, wind energy is clean, renewable and can be easily turned into mechanical vibrations that can be used to generate electrical energy via vibration-to-electrical energy conversion mechanisms using electromagnetic, electrostatic and piezoelectric transducers. 4,5 Of these transducers, piezoelectric materials have received the most attention because of their higher conversion efficiency. 6,7 Flutter is an aerodynamic phenomenon that occurs when a structure is subjected to flow loads, and this motion can be used to harvest wind energy in many applications using a piezoelectric cantilever.…”

A utility piezoelectric energy harvester with low frequency and high-output voltage: Theoretical model, experimental verification and energy storage AIP Advances 6, 095208 (2016); https://doi.org/10.1063/1.4962979 Piezoelectric energy harvesting: State-of-the-art and challenges Applied Physics Reviews 1, 031104 (2014); https://doi.org/10.1063/1.4896166 AIP ADVANCES 6, 055002 (2016) Performance of pre-deformed flexible piezoelectric cantilever in energy harvesting This paper proposes a novel structure for pre-rolled flexible piezoelectric cantilevers that use wind energy to power a submunition electrical device. Owing to the particular installation position and working environment, the submunition piezoelectric cantilever should be rolled when not working, but this pre-rolled state can alter the energy harvesting performance. Herein, a working principle and installation method for piezoelectric cantilevers used in submunitions are introduced. To study the influence of the pre-rolled state, pre-rolled piezoelectric cantilevers of different sizes were fabricated and their performances were studied using finite element analysis simulations and experiments. The simulation results show that the resonance frequency and stiffness of the pre-rolled structure is higher than that of a flat structure. Results show that, (1) for both the pre-rolled and flat cantilever, the peak voltage will increase with the wind speed. (2) The pre-rolled cantilever has a higher critical wind speed than the flat cantilever. (3) For identical wind speeds and cantilever sizes, the peak voltage of the flat cantilever (45 V) is less than that of the pre-rolled cantilever (56 V). (4) Using a full-bridge rectifier, the output of the pre-rolled cantilever can sufficiently supply a 10 µF capacitor, whose output voltage may be up to 23 V after 10 s. These results demonstrate that the pre-rolled piezoelectric cantilever and its installation position used in this work are more suitable for submunition, and its output sufficiently meets submunition requirements.

“…In [29], a piezofiber energy harvester was developed and mounted inside the tire to provide 34.5 μJ for one wheel cycle. Wang et al [30][31][32] developed pendulum-based energy harvesters for harvesting the kinetic energy from a rotating wheel. The generated power ranged from 300 to 400 μW at wheel speeds between 300 and 500 rpm.…”

Abstract:The objective of this study is to develop and analyze a nonlinear suspended energy harvester (NSEH) that can be mounted on a rotating wheel. The device comprises a permanent magnet as a mass in the kinetic system, two springs, and two coil sets. The mass vibrates along the transverse direction because of the variations in gravitational force. This research establishes nonlinear vibration equations based on the resonance frequency variation of the energy harvester; these equations are used for analyzing the power generation and vibration of the harvester. The kinetic behaviors can be determined according to the stiffness in the two directions of the two suspended springs. Electromagnetic damping is examined to estimate the power output and effect of the kinematic behaviors on NSEH. The power output of the NSEH with a 52 Ω resistor connected in series ranged from approximately 30 to 4200 μW at wheel speeds that ranged from nearly 200 to 900 rpm.
