“…With the increase of CB contents, CB NPs were gradually exposed to the surface of fibers, which made the fiber surface rougher, leading to the increase of WCA of BNFM. All BNFMs exhibited hydrophobicity, which helped to reduce frictional charge dissipation and improve adaptability to ambient humidity. , Furthermore, the formation of a beaded structure was not affected by the increase in CB content. It was worth noting that when excessive CB content was added to TPU solution, the ES process might be more difficult due to the high viscosity of the solution and its barely increased conductivity, which made the prepared fiber too fine and easy to fracture, as shown in Figure f.…”

Triboelectric nanogenerators (TENGs) are capable of sustainably powering wearable sensors by harvesting diverse forms of ambient mechanical energy. Nevertheless, the material and structural designs of friction layers have significant impacts on the performance of TENGs. Electrospun nanofibers can enhance the electrical performance of wearable TENG because of their large specific surface area and porosity. Herein, the free-surface electrospinning technique was used to prepare the positive and negative friction layers with special structures of TENGs. The porous nanofiber membrane (NFM) of polylactic acid (PLA)/chitosan (CS)/aloin with good biocompatibility was used as the positive friction layer of TENGs. Furthermore, a certain amount of carbon black (CB) nanoparticles (NPs) were loaded into thermoplastic polyurethanes (TPU) to prepare beaded NFMs (BNFMs), which helped to improve the hydrophobicity and charge storage capability of the negative friction layer. The morphology of BNFMs with various CB contents and their electrical output performances as negative friction layers were compared, respectively. It was found that the BNFMs could deform under different pressures to enhance the contact area and electrical output of TENG. Moreover, the BNFMs loaded with CB can not only increase their surface roughness but also enhance the charge transfer rate and storage capacity of the friction layer. This provided TENG with good electrical output, high stability, and durability, as well as great application potential in harvesting various types of biomechanical energies. In addition, the proposed all-electrospun TENG had better flexibility, wearing comfort, and fabricating ease, which could be adhered to the human body for sensing human motion when embedded into textiles.

“…A typical example is the preparation of all-fiber structured TENG of electrospun PA66/MWCNTs nanofiber and conductive fabric. [247] In addition, a series of e-textiles prepared from microstructured electrospun films (e.g., silk, [134] PLA, [253] PS, [77,244] PVDF [234,245] ) have been developed for wearable TENG devices. For example, electrospun microspheres are frequently used in the preparation of wearable TENGs for collecting human motion energy such as walking and knee bending (Figure 12a).…”

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.

Some progress has already been made in this direction by using electrospinning to create a greater density of fibre contacts [49][50][51][52][53][54][55][56][57][58][59]. A comprehensive review of electrospun nanofibre based TENGs for wearable applications is given in Babu et al [59].…”
