“…The PTFE‐based device generated higher output performance due to the PTFE having the extreme potential to attract the electrons from tribopositive layer and the PET derived the second higher performance than PTFE due to the moderate electron attracting potential. [ 65 ] These results suggested that the tribopositive DRF thin film and tribonegative PTFE is an emerging pair to get the superior output. The DRFs/PTFE nanogenerator pair used for the further experiments.…”

Sustainable energy harvesting technologies for maintaining the social ecosystem are predominantly addressing global challenges. Nowadays, non‐toxic and low‐cost energy‐generating nature materials are getting great attention for the development of flexible triboelectric nanogenerators (TENGs). Herein, Delonix regia flowers (DRFs) derived biowaste‐based tribopositive material are used to develop the high‐performance triboelectric nanogenerator. DRFs have the presence of carbonyl, hydroxyl, and amino acids functional groups, which plays a key role to demonstrate the electron‐donating ability of the DRFs. The proposed DRFs/PTFE device with a 20 cm2 size and 6 mm separation distance exhibits a higher performance of voltage (655 V), current (59 μA), and instantaneous power (220.2 μW cm−2) under uniform external stress at 10 Hz frequency by air cylinder motor. It has also investigated the performance of the different device sizes and the spacing effect between triboelectric layers. The DRFs/PTFE‐structured TENG exhibits excellent ability to lit up the 210 light emitting diodes and run up the low‐power electronic stopwatch. According to the presented results, DRFs could be a superior candidate for triboelectric nanogenerator applications.

“…Therefore, many applications of different MOFs materials were developed by modifying the crystal structures and enhancing their properties, which maximized the value of MOFs materials in TENG. [253][254][255][256][257][258][259][260][261] In 2018, Seol et al reported the triboelectric charging behaviors of various 2D materials in a triboelectric series (Figure 13g). They proved an important insight to utilize 2D materials in TENG.…”

The Internet of Things (IoT) is poised to accelerate the construction of smart cities. However, it requires more than 30 billion sensors to realize the IoT vision, posing great challenges and opportunities for industries of self‐powered sensors. Triboelectric nanogenerator (TENG), an emerging new technology, is capable of easily converting energy from surrounding environment into electricity, thus TENG has tremendous application potential in self‐powered IoT sensors. At present, TENG encounters a bottleneck to boost output for large‐scale commercial use if just by promoting triboelectric charge generation, because the output is decided by the triboelectric charge dynamic equilibrium between generation and decay. To break this bottleneck, the strategy of reducing triboelectric charge decay to enhance TENG output is focused. First, multiple mechanisms of triboelectric charge decay are summarized in detail with basic theoretical principles for future research. Furthermore, recent advances in reducing triboelectric charge decay are thoroughly reviewed and outlined in three aspects: inhibition and application of air breakdown, simultaneous inhibition of air breakdown and triboelectric charge drift/diffusion, and inhibition of triboelectric charge drift/diffusion. Finally, challenges and future research focus are proposed. This review provides reference and guidance for enhancing TENG output.

“…Most 2D materials have been investigated theoretically or experimentally for the demonstration of piezoelectricity, but the majority of them have not been demonstrated for energy harvesting applications. MOFs are multifunctional materials that have been demonstrated for TENG-based self-powered sensing and the enhancement of β-phase in the PVDF for PENG [219]. However, many MOFs exhibit a non-centrosymmetric space group indicating the presence of potential piezoelectricity in the MOFs, which has not yet been investigated.…”

The ever-increasing demand for energy as a result of the growing interest in applications such as Internet of Things (IoT), and wearable systems etc. call for the development of self-sustained energy harvesting solutions. In this regard, the 2D materials have sparked an enormous interest recently, owing to their outstanding properties such as ultra-thin geometry, high electromechanical coupling, large surface area to volume ratio, tunable band gap, transparency and flexibility. This has unravelled noteworthy advancements in energy harvesters like triboelectric nanogenerator (TENG), piezoelectric nanogenerator (PENG) and photovoltaics (PV) based on 2D materials. This review introduces the properties of different 2D materials including graphene, transition metal dichalcogenides (TMDs), MXenes, black phosphorous (BP), hexagonal boron nitride (h-BN), metal-organic frameworks (MOFs) and covalent organic frameworks (COFs). A detailed discussion of the recent developments in the 2D materials-based PENG, TENG and photovoltaic devices is included. The review also considers the performance enhancement mechanism and importance of 2D materials in energy harvesting. Finally, the challenges and future perspectives are laid out to present a future research direction for the further development and extension of 2D materials-based energy harvesters.
