Summary Nanogenerators is the growing technology that facilitates self‐powered systems, sensors, and flexible and portable electronics in the thriving era of internet of things (IoT). Since the first invention of the triboelectric nanogenerators (TENGs) in 2012, it has become one of the most important inventions in energy harvesting technologies. In this paper, a brief review on the recent progress of energy harvesting research based on TENGs technology is discussed. Basic working modes of the TENG are discussed in detail and the general procedure to synthesize, measure, and characterize a nanogenerator is presented in a direct structure. The triboelectric material choices are extremely important for TENGs since the triboelectric effects of the materials are fundamental for TENGs. The materials used as triboelectric layers are varied from polymers, metals, and inorganic materials with the commonly used materials are dielectric polymers such as PTFE, PVDF, PDMS, nylon, and Kapton. Recently, two‐dimensional (2D) materials have been widely reported as candidate materials for TENGs. Graphene, the most attractive 2D materials exhibits an excellent electrical property, great flexibility, and a high surface‐to‐volume ratio. Owing to the very low thickness of the atomic unit, a stacking graphene structure can be also made to form a very thin and miniature TENGs device. The major applications of the graphene as active materials for TENGs as a sustainable energy harvester are presented, following which structural designs and materials optimization for output performance improvement of the graphene‐based TENGs are summarized. Finally, the future directions and perspectives of the graphene‐based TENGs are outlined. The graphene‐based TENGs is not only a sustainable micro‐power source for small devices, but also serves as a potential macro‐scale generator of power from blue energy in the future.

“…For the comfortable TENG operation under the same mechanical stimuli, the custom fabricated ferromagnetic composite film of iron-silicon chromium (FeSiCr)/polydimethylsiloxane (PDMS) is utilized, [31,33] which along with spherical magnet assist in the self-actuation of the TENG based on magnetic attraction principle for periodic contact separation between the TENG layers. Owing to an excellent triboelectric property of MXene based composites, [57][58][59] a composite nanofiber of 2D MXene/ polyvinylidene fluoride (PVDF) and Nylon 6/6 are utilized as pairing materials to achieve adequate signal stability and accuracy in water wave parameter sensing. The as-fabricated HSP-AWMSS has been tested under arbitrary motion circumstances to highlight its major potentialities of high-performance energy harvesting and self-powered wave motion sensing.…”

Imbalances in these factors are sure for outbursting the waves thus causing natural disasters that adversely impact living beings. To ensure on-time prediction and timely alert regarding unexpected wave activities various technologies have been deployed. [3][4][5][6][7][8][9][10][11][12][13] In fact, water wave monitoring is highly effective in weather forecasting, [3] Oceanography, [4] marine navigation, [5] aquaculture, [6] and exploring sea resources. [7] Currently, various technologies such as accelerometer buoys, [8] and more advanced technologies such as global positioning system, [9] underwater vehicles, [10] imaging techniques, [11] advanced sensor networks, [12] and permanent technologies such as surface water buoys, navigational buoys, drifter buoys are commonly employed. [13] However, these technologies require continuous external power for undisrupted operation, which is hard to manage in remote seashore areas. To date, energy alternatives such as photovoltaic panels, [14] and wind turbines [15] are being employed. However, these technologies are also suffering from daylight necessity and continuous wind blow requirements. In the same course, water kinetic energy is massive and widely distributed which is insensitive to the weather, seasons, and sunlight. Therefore, it's preferable to use low-cost, non-intrusive, reliable, scalable, self-powered, and autonomous systems that can survive for a long period in remote locations. As for sustainable and clean energy alternatives, research communities are highly focused on developing generators and self-powered sensors based on various transduction principles such as electromagnetic, [16] triboelectric, [17][18][19][20][21][22][23][24][25][26][27][28][29] piezoelectric, [30] and the hybrid principle.

“…Thus, in the aspect of material science, the direct way to enhance the charge transferring efficiency is to improve the properties of materials. Via incorporating ZnO nanorods [27] or electrospun MXene (Ti3C2Tx) [28] into polyvinylidene fluoride (PVDF) polymer, triboelectrification can be considerably enhanced. Functionalizing polydimethylsiloxane (PDMS) with polystyrene (PS) and pentafluorostyrene (PPFS) [29] is also an effective way.…”

The majority of research work on triboelectric energy harvesting is on material science, manufacturing and electric circuit design. There is a lack of in-depth research into structural dynamics which is crucial for power generation in triboelectric energy harvesting. In this paper, a novel triboelectric energy harvester with a compact structure working in sliding mode is developed, which is in the form of a casing and an oscillator inside. Unlike most sliding-mode harvesters using single-unit films, the proposed harvester utilizes grating-patterned films which are much more efficient. A bistable mechanism consisting of two pairs of magnets is employed for broadening the frequency bandwidth. A theoretical model is established for the harvester, which couples the structural dynamics domain and electrical dynamics domain. This paper presents the first study about the nonlinear structural dynamics of a triboelectric energy harvester with grating-patterned films, which is also the first triboelectric energy harvester integrating grating-patterned films with a bistable magnetic system for power performance enhancement. Theoretical studies are carried out from the perspectives of both structural and electrical dynamics. A comparison between the coupled model and uncoupled model reveals that the electrostatic force between the electrodes can be neglected. Great differences in structural response and electrical output are found between a velocity-dependent model and Coulomb’s model for modelling the friction in the harvester. The bistable mechanism can effectively improve the output voltage under low-frequency excitations. Additionally, the output voltage can also be obviously enhanced through increasing the number of the hollowed-out units of the grating-patterned films, which also results in a slight decrease of the optimal load resistance of the harvester. These findings enable innovative designs for triboelectric energy harvesters and provide fabrication guidelines in practical applications.
