“…Figure 15 compares the performances of different VEHs in diverse frequency ranges. 55,56 Comparisons of EM, PE, ES, MS, pyroelectric, RF, and photovoltaic effects have been performed, and combinations of these energy sources have proved encouraging; however, miniaturisation and segmented microgenerators are needed. Overall, the hybrid arrangement performs better over a broad frequency range and in a multi-energy context.…”

Summary Energy harvesting technologies are growing rapidly in recent years because of limitation by energy storage and wired power supply. Vibration energy is abundant in the atmosphere and has the potential to be harvested by different mechanisms, mainly through piezoelectric and electromagnetic means. Various architectural structures were also designed for several operating conditions, namely, resonance frequency and range thereof, acceleration, and energy extraction from several motions. The advantages and disadvantages were elaborated on, and improvements on ideas from current research were discussed in this review.

“…10 Most researchers focus on the scavenging of linear vibration energy which is ubiquitous in the ambient environment. [11][12][13][14] In contrast, rotational energy has been less studied and used as the power source. Nevertheless, energy harvester to collect energy from rotary motion can be very useful for many practical applications, such as the condition monitoring of rotating machine, 15 tire pressure monitoring, 16 and wind energy harvesting.…”

An integrated multi-source energy harvester based on vibration and magnetic field energy AIP Advances 8, 056623 (2018) This paper proposes a rotational energy harvester using a piezoelectric bistable buckled beam to harvest low-speed rotational energy. The proposed harvester consists of a piezoelectric buckled beam with a center magnet, and a rotary magnet pair with opposite magnetic poles mounted on a revolving host. The magnetic plucking is used to harvest the angular kinetic energy of the host. The nonlinear snap-through mechanism is utilized to improve the vibration displacement and output voltage of the piezoelectric layer over a wide rotation frequency range. Theoretical simulation and experimental results show that the proposed energy harvester can yield a stable average output power ranging between 6.91-48.01 µW over a rotation frequency range of 1-14 Hz across a resistance load of 110 kΩ. Furthermore, dual attraction magnets were employed to overcome the suppression phenomenon at higher frequencies, which yields a broadband and flat frequency response over 6-14 Hz with the output power reaching 42.

“…Two major principles are used to broaden frequency response range of the piezoelectric energy harvester, that is, nonlinear operation principle and multifrequency principle. Nonlinear behavior of piezoelectric energy harvester can be achieved by several active and passive techniques like stiffness tuning, axial preload, and magnetic coupling operation [12][13][14][15].…”

This paper focuses on numerical and experimental investigations of a novel design piezoelectric energy harvester. Investigated harvester is based on polygon-shaped cantilever array and employs multifrequency operating principle. It consists of eight cantilevers with irregular design of cross-sectional area. Cantilevers are connected to each other by specific angle to form polygonshaped structure. Moreover, seven seismic masses with additional lever arms are added in order to create additional rotation moment. Numerical investigation showed that piezoelectric polygon-shaped energy harvester has five natural frequencies in the frequency range from 10 Hz to 240 Hz, where the first and the second bending modes of the cantilevers are dominating. Maximum output voltage density and energy density equal to 50.03 mV/mm 3 and 604 J/mm 3 , respectively, were obtained during numerical simulation. Prototype of piezoelectric harvester was made and experimental investigation was performed. Experimental measurements of the electrical characteristics showed that maximum output voltage density, energy density, and output power are 37.5 mV/mm 3 , 815.16 J/mm 3 , and 65.24 W, respectively.
