“…The DLC/polymer-based TENG exhibited good durability by producing a more stable output current compared with other parts during the 3 h operation at an applied force of 9.8 N. Wang et al [166] devised a new DLC-based TENG with a macroscale superlubricity that can withstand high-contact stress (a Hertz contact stress of 1.37 GPa) with ultralow friction coefficient (<0.01) and ultralow wear rate (Figure 20a-c). After the DLC film undergone a friction process of 1, 2, and 3 h, the wear rate did not drastically change indicating long-term operating life at a applied force of 10 N. Tremmel et al [167] found the DLC coating performed superior performance compared to MoS 2 . The DLC film also withstood long-term tests without notable signs of wear after 9000 cycles during 1 Hz and 2.3 N. It is also found that MXenes outperformed the other coatings due to the good electron gain ability of functional oxygen and fluorine groups (Figure 20d).…”

Triboelectric nanogenerators (TENGs) have attracted great interests in the development of sustainable energies and intelligent society. However, a big challenge for TENGs in practical applications is the unavoidable external mechanical abrasion and/or contaminant adsorption on the triboelectric materials, which leads to the significant decrease of the durability of TENGs and is urgently needed to be addressed. There are already a series of interesting progresses on the topic of the TENGs' durability. In this study, reviewing the durability of TENGs via both the advanced materials/structure designing and the novel surface/interface engineering is focused upon, which includes choosing basic TENG materials, improving composites performance, optimizing structures, and designing triboelectric surfaces and interfaces. To get a better understanding of the durability of TENGs in published studies, the quantifiable levels of service life are also summarized including operation cycles, time, friction coefficient, and wear loss of triboelectric materials, where the boosting mechanisms are also discussed and summarized. Finally, the challenges as well as key strategies toward high durable TENGs are presented.

Natural sources of green energy include sunshine, water, biomass, geothermal heat, and wind. These energies are alternate forms of electrical energy that do not rely on fossil fuels. Green energy is environmentally benign, as it avoids the generation of greenhouse gases and pollutants. Various systems and equipment have been utilized to gather natural energy. However, most technologies need a huge amount of infrastructure and expensive equipment in order to power electronic gadgets, smart sensors, and wearable devices. Nanogenerators have recently emerged as an alternative technique for collecting energy from both natural and artificial sources, with significant benefits such as light weight, low-cost production, simple operation, easy signal processing, and low-cost materials. These nanogenerators might power electronic components and wearable devices used in a variety of applications such as telecommunications, the medical sector, the military and automotive industries, and internet of things (IoT) devices. We describe new research on the performance of nanogenerators employing several green energy acquisition processes such as piezoelectric, electromagnetic, thermoelectric, and triboelectric. Furthermore, the materials, applications, challenges, and future prospects of several nanogenerators are discussed.

Triboelectric Nanogenerators (TENGs) represent a novel energy harvesting technology that combines contact electrification (CE) and electrostatic induction, rendering them a promising solution for self‐powering micro smart devices and addressing the energy crisis. At present, the efficiency and longevity of TENGs have been substantially improved through various methods. These advancements have overcome the limitations caused by interface friction, expanding the scalability and practical applications of TENGs. Specifically, it has been demonstrated that interface tribological optimization can simultaneously enhance electrical output performance and durability. This review will initially discuss the fundamental mechanism of TENGs and its profound connection with tribology. Subsequently, the optimization of interface tribology, encompassing structure design, surface modification, and lubricant utilization, will be comprehensively reviewed. Finally, the current challenges and future prospects will be summarized.
