Nowadays, a large number of sensors are employed in the oceans to collect data for further analysis, which leads to a large number of demands for battery elimination in electronics due to the size reduction, environmental issues, and its laborious, pricy, and time-consuming recharge or replacement. Numerous methods for direct energy harvesting have been developed to power these low-power consumption sensors. Among all the developed harvesters, piezoelectric energy harvesters offer the most promise for eliminating batteries from future devices. These devices do not require maintenance, and they have compact and simple structures that can be attached to low-power devices to directly generate high-density power. In the present study, an atlas of 85 designs of piezoelectric energy harvesters in oceanic applications that have recently been reported in the state-of-the-art is provided. The atlas categorizes these designs based on their configurations, including cantilever beam, diaphragm, stacked, and cymbal configurations, and provides insightful information on their material, coupling modes, location, and power range. A set of unified schematics are drawn to show their working principles in this atlas. Moreover, all the concepts in the atlas are critically discussed in the body of this review. Different aspects of oceanic piezoelectric energy harvesters are also discussed in detail to address the challenges in the field and identify the research gaps.

“…Harvesting energy from ambient vibrations, such as winding, human motion, vehicles, machines and buildings, etc., have been reorganized as a feasible solution to supply green energy to wireless sensor nodes [ 1 , 2 , 3 , 4 , 5 , 6 ], which can be implemented by using electromagnetic [ 7 , 8 ], electrostatic [ 9 ] and piezoelectric [ 10 , 11 ] transduction mechanisms to convert mechanical energies into electricity. Among them, piezoelectric vibration energy harvesters (PEVHs) have been highlighted because of its high-power density, ease of implementation and miniaturization [ 5 , 12 , 13 ]. Typically, a PEVH can be constructed by a proof mass to capture the vibration, a piezoelectric plate to convert the energy and a substrate to support the mass and plate [ 14 ].…”

This paper proposes a multidirectional piezoelectric vibration energy harvester based on an improved U-shaped structure with cross-connected beams. Benefitting from the bi-directional capacity of U-shaped beam and additional bending mode induced by cross-connected configuration, the proposed structure can well capture the vibrations in 3D space at the frequencies lower than 15 Hz. These features are further validated by finite element analyses and theorical formulas. The prototype is fabricated and the experiments under different conditions are carried out. The results show that the proposed harvester can generate favorable voltage and power under multidirectional vibrations at a low operating frequency. Practical applications of charging capacitors and powering a wireless sensor node demonstrate the feasibility of this energy harvester in supplying power for engineering devices.

“…The radially entrained magnetic force was used to collect energy. In [32], the authors considered and analyzed the collection of piezoelectric energy from the characteristics of compliant mechanisms. The authors divided configurations into monostable, multistable, multiple degrees of freedom, frequency upconversion and under load optimization.…”

A computational and experimental approach to modeling oscillations of a new axial-type piezoelectric generator (PEG) with an attached mass and an active base is considered. A pair of cylindrical piezoelements located along the generator axis is used as an active base. Plate-type piezoelectric elements, made in the form of two bimorphs on an elastic PEG base, use the potential energy of PEG bending vibrations. Energy generation in cylindrical piezoelectric elements occurs due to the transfer of compressive forces to the piezoelectric element at the base of the PEG during excitation of structural vibrations. The active load scheme is selected separately for each piezoelectric element. Numerical simulation was performed in the ANSYS FE analysis package. The results of modal and harmonic analysis of vibrations are presented. A technique for experimental analysis of vibrations is presented, and a laboratory test setup is described. Numerical and experimental results are presented for the output characteristics of a piezoelectric generator at a low-frequency load. For one of the versions of the generator and a certain displacement amplitude for a frequency of 39 Hz, in the results of a comparative experimental analysis at a load of 10 kΩ, the maximum output power for each cylindrical piezoelectric element was 2138.9 μW, and for plate-type piezoelectric elements, respectively, 446.9 μW and 423.2 μW.
