The properties of materials play a significant role in triboelectric nanogenerators (TENGs). Advanced triboelectric materials for TENGs have attracted tremendous attention because of their superior advantages (e.g., high specific surface area, high porosity, and customizable macrostructure). These advanced materials can be extensively applied in numerous fields, including energy harvester, wearable electronics, filtration, and self‐powered sensors. Hence, designing triboelectric materials as advanced functional materials is important for the development of TENGs. Herein, the structural modification methods based on electrospinning to improve the triboelectric properties and the latest research progress in this kind of TENGs are systematically summarized. Preparation methods and design trends of nanofibers, microspheres, hierarchical structures, and doping nanomaterials are highlighted. The factors influencing the formation and properties of triboelectric materials are considered. Furthermore, the latest progress on the applications of TENGs is systematically elaborated. Finally, the challenges in the development of triboelectric materials are discussed, thereby guiding researchers in the large‐scale application of TENGs.

“…Triboelectric nanogenerators (TENGs) have become a promising solution for the creation of HMIs due to their energy autonomy, wide selection of materials, cost efficiency, and easy manufacturability. , Many advanced triboelectric sensor-based HMIs have been reported, including keyboards, − gloves, − glasses, − and electronic skins. − However, these HMIs are limited to a few buttons and functions, making it difficult to implement more complex interactive applications. Moreover, they are not implemented naturally or require an additional learning phase of operational instructions.…”

The rapid development of artificial intelligence places high demands on human–machine interfaces. Various types of huma–machine interfaces have been implemented, including smart keyboards, electronic skins, and wearable motion sensors. Handwriting behavior has a high degree of interaction freedom, and handwriting characteristics offer high-security standards for human–machine systems. Herein, we propose a portable smart pen integrated with triboelectric displacement vector sensors to trace handwriting trajectories for human–machine interactions and biometric identification. A triboelectric pressure sensor array is evenly distributed along the pen case to sense displacement vectors, and an additional triboelectric sensor is placed on top of the pen to detect vertical force. By leveraging the resin pen refill as a tribopositive material and a nanowired polyethylene tribonegative layer attached to a Cu electrode, triboelectric signals are generated during the writing/moving process. The calculation and analysis of the sensor signals enable the recognition of handwritten patterns, including Latin letters and Arabic numerals. Moreover, the smart pen can be used to authenticate users based on their unique handwriting patterns, which can help take human–machine interfaces and cyber security to the next level. Furthermore, a custom smart pen operation mode that enables the control of a slide presentation demonstrates the smart pen’s potential for various human–machine interface applications.

“…Herein, we proposed to use the recyclates for fabricating high-performance durable triboelectric nanogenerators (TENGs) and efficient CO 2 capture adsorbents. TENGs are designed to generate electricity by the triboelectrification of two tribopolar materials. − Recently, TENGs have attracted significant attention in modern electronics, especially for wearable devices and self-powered nanodevices, as they can scavenge mechanical energy from the ambient vibrations to produce electricity. ,− A variety of TENGs made from cellulose materials such as cellulose nanofibers (CNFs), cellulose nanocrystals (CNCs), and bacterial cellulose (BC) have been reported ,,− as these materials are naturally biodegradable, renewable, and biocompatible. , However, the CA used in CFs is a chemically derived product of pure cellulose, and it takes a much longer time (several years depending on the surrounding environment) to degrade naturally in the environment . Hence, the technology that can enhance the life cycle of the filter fibers and revitalize them would be of high importance.…”

This article reports a novel and rational approach to convert waste cigarette filters (CFs), one of the largest sources of ocean pollution, into high-performance triboelectric nanogenerators (TENGs) and efficient CO2-capturing adsorbents. CFs are plasticized cellulose acetate, which take several years to degrade. To revalorize these fibers, selective amine surface functionalization is performed (10PAL-20T-CFs). For the proof of concept, when the modified fibers are employed in a TENG, it could generate an output voltage (96.63 V) and current (9.37 μA) that are, respectively, 43 and 8 times higher than those obtained employing the pristine CFs for the nanogenerator. The proposed TENG displays an instantaneous peak power of 3.75 mW, which is higher than that of many recently reported TENGs made from cellulose materials. Moreover, the TENG displayed outstanding durability to humidity and high-performance stability when it is subjected to cyclic loading (i.e., 12,000 cycles of loading–unloading). A 9 cm2 TENG could effectively light up 100 or more colored light-emitting diodes when it is manually pressed. Finally, the modified filter fibers show an excellent CO2 adsorption capacity of 1.93 mmol/g, which is 9.2 times higher than that obtained using the pristine fibers. These results demonstrate that hazardous wastes such as CFs can be upcycled into valuable resources.
