“…These two materials have different nanoscale surface roughness, in which allows for friction through a relative sliding between the two materials when the TENGS is operated. Since then, many triboelectric materials had been used in TENGs, such as polymers (polyamide, polytetrafluoroethylene [PTFE], polydimethylsiloxane [PDMS], polyvinylidene fluoride [PVDF]), 13,[23][24][25][26][27][28] metals (Aluminum, 29 Nickel, 30 Copper, 31 Steel, 32 Gold 33 ) etc. Even though typical TENGs consist of above triboelectric materials is preferred due to the flexibility and good triboelectricity of the polymers as well as high conductivity of the metals based TENGs.…”

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.

“…6 d. Finger approaches the sensor at a constant speed (0.5 cm s −1 ) at a distance from the sensor (6 cm) and then leaves at the same speed. Table 2 summarizes the humidity sensing performance of the presented PEHS in comparison with previous works [ 24 , 25 , 53 , 54 ]; the comparison highlights the PEHS has much higher response in a wide RH range. Figure S3b shows the long-term stability of PVA/MXene nanofibers film sensor driven by PENG over a period of 30 days.…”

Two-dimensional material has been widely investigated for potential applications in sensor and flexible electronics. In this work, a self-powered flexible humidity sensing device based on poly(vinyl alcohol)/Ti3C2Tx (PVA/MXene) nanofibers film and monolayer molybdenum diselenide (MoSe2) piezoelectric nanogenerator (PENG) was reported for the first time. The monolayer MoSe2-based PENG was fabricated by atmospheric pressure chemical vapor deposition techniques, which can generate a peak output of 35 mV and a power density of 42 mW m−2. The flexible PENG integrated on polyethylene terephthalate (PET) substrate can harvest energy generated by different parts of human body and exhibit great application prospects in wearable devices. The electrospinned PVA/MXene nanofiber-based humidity sensor with flexible PET substrate under the driven of monolayer MoSe2 PENG, shows high response of ∼40, fast response/recovery time of 0.9/6.3 s, low hysteresis of 1.8% and excellent repeatability. The self-powered flexible humidity sensor yields the capability of detecting human skin moisture and ambient humidity. This work provides a pathway to explore the high-performance humidity sensor integrated with PENG for the self-powered flexible electronic devices.

“…The TENG is a promising technology for the acquisition of environmental mechanical energy. Through the principles of triboelectric charging and electrostatic induction, it can well transform the mechanical energy of the surrounding environment and human body into electrical energy. − This can provide power to drive some low-power systems or devices. TENG’s high efficiency at low frequencies is unmatched by conventional electromagnetic generators.…”

Tens of thousands of plastics produced by people have caused incalculable harm to the environment. At the same time, the consumption of energy is becoming more and more serious, and the use of fossil energy to generate electricity has caused further damage to the environment. It is a good way to recycle waste plastics and make energy collection and generation devices based on them. Here, a triboelectric nanogenerator (TENG) based entirely on waste plastic bags is proposed. Three types of TENGs, PA-PVC-TENG, PA-PE-TENG, and PVC-PE-TENG, were fabricated by selecting the most common PA, PVC, and PE plastic films as the triboelectric layer. The output performance was improved by gilding the back of the plastic films as a conductive electrode. Under different conditions, three different types of TENGs were tested. The PA-PVC-TENG was found to show the best output performance with an open-circuit voltage of 35.7 V, a short-circuit current of 5.85 μA, and a maximum output power density of 152.6 mW/m2. After further integration with supercapacitors, the integrated system can drive multiple commercial LEDs, and it can be used as an antitheft device to achieve early warning. This study realizes the integration of a TENG and energy storage devices, and as a TENG is based entirely on waste plastic bags, it not only realizes the recycling of plastics but also further realizes power generation, which can alleviate energy consumption to some extent.
