“…(1), the voltages V 1 and V 2 have been solved, and the relationship between the two resonant frequencies has already been determined. (25) The parameters affecting the performance of the proposed PMEH include the coupling strength of the first and second piezoelectric elements, the mass ratio m 1 /m 2 , the stiffness ratio k 1 /k 2 , and the damping Table 1. The resonant frequency of the designed PMEH was simulated by ANSYS software.…”

“…The measured resonant frequency gradually decreases with increasing vibration acceleration, which is caused by the nonlinear change in the Young's modulus of PZT. (25) The maximum open-circuit output voltage increases with the vibration acceleration. When the vibration acceleration increases from 0.5 to 2.0 g, the maximum peak-peak voltage under the open-circuit condition is determined to be 7.6, 13, 18, and 23.6 V at the above-mentioned four vibration accelerations, respectively.…”

Keywords: piezoelectric energy harvester, two-degree-of-freedom, MEMS, bulk PZT film In this paper, we propose a low-frequency (<100 Hz) piezoelectric MEMS energy harvester (PMEH) with a two-degree-of-freedom (2DOF) structure to work in two vibration modes for broadband operation. The PMEH is fabricated by bonding a piezoelectric ceramic lead zirconate titanate Pb(Zr,Ti)O 3 (PZT) to phosphor bronze, which can work in a high-acceleration ambient with good durability. The maximum open-circuit voltage and output power of the PMEH are 23.6 V and 64.69 μW at the first resonant frequency of 27.4 Hz when the input vibration acceleration is 2 g (9.8 m/s 2 ), while they are 14 V and 56.75 μW at the second resonant frequency of 93.4 Hz when the input vibration acceleration is 8 g, respectively. The fabricated PMEH scavenged the vibration energy of a vacuum compression pump and an ultrasonic cleaner and generated maximum output powers of 10.45 and 16.59 μW, respectively. The experimental results show that the device has good environmental adaptability.

“…The testing was done on two different stages; a dry testing in the lab using a ball screw mechanism to drive the buoy, and a wet testing in a wave tank. Typical PTOs work well with high velocity mechanisms and low forces, like piezoelectric elements that are used to harvest energy from environmental vibration [99,100]. These piezoelectric PTOs have been proposed before for wave energy harvesting [101], but the implementation and efficiency are very questionable given that they work for very high frequencies, a magnitude or two higher than the ocean waves frequencies.…”

Even though ocean waves around the world are known to contain high and dense amounts of energy, wave energy harvesters are still not as mature as other forms of renewable energy harvesting devices, especially when it comes to commercialization, mass production, and grid integration, but with the recent studies and optimizations, the point absorber wave energy harvester might be a potential candidate to stand out as the best solution to harvest energy from highly energetic locations around the world’s oceans. This paper presents an extensive literature review on point absorber wave energy harvesters and covers their recent theoretical and experimental development. The paper focuses on three main parts: One-body point absorbers, two-body point absorbers, and power take-offs. This review showcases the high amount of work being done to push point absorbers towards technological maturity to eventually kick off commercialization and mass production. It should also provide a good background on the recent status of point absorber development for researchers in the field.

“…Numerous implementations of multi-frequency energy harvesters are proposed till now. For example multi-frequency energy harvesters with double mass (Qu and et al 2011),fractal-inspired (Castagnetti, 2016), two degree of freedom (2-DOF) (Wu and et al 2012) or multiple degree of DOF (Xiao and et al 2016), zigzag shaped (Lee and et al 2018;Zhou and et al 2017b) and etc. Extensive investigations and reported results shows that multi-frequency energy harvesters have huge potential.…”
