“…It is commonly paired with negative friction materials such as PVDF and PTFE to produce a large potential difference (Table 5). [196,197] Some researchers have improved the properties of polyamide-based positive friction materials through surface coating, cationic functionalization, nanocomposite preparation, and electric field regulation strategies. [198,199] Rana et al reported the performance of TENGs with poly(diallyldimethylammonium chloride) (poly-DADMAC)/nylon-11 composite nanofibers as a highly positive triboelectric layer.…”

Over the past few decades, significant progress in piezo‐/tribo‐electric nanogenerators (PTEGs) has led to the development of cutting‐edge wearable technologies. Nanofibers with good designability, controllable morphologies, large specific areas, and unique physicochemical properties provide a promising platform for PTEGs for various advanced applications. However, the further development of nanofiber‐based PTEGs is limited by technical difficulties, ranging from materials design to device integration. Herein, we systematically review the current developments in PTEGs based on electrospun nanofibers. The review begins with the mechanisms of PTEGs and the advantages of nanofibers and nanodevices, including high breathability, waterproofness, scalability, and thermal–moisture comfort. In terms of materials and structural design, novel electroactive nanofibers and structure assemblies based on one‐dimensional micro/nanostructures, two‐dimensional bionic structures, and three‐dimensional multilayered structures are discussed. Subsequently, nanofibrous PTEGs in applications such as energy harvesters, personalized medicine, personal protective equipment, and human‐machine interactions are summarized. Nanofiber‐based PTEGs still face many challenges such as energy efficiency, material durability, device stability, and device integration. In the final section of this review, the research gap between research and practical applications of PTEGs is discussed, and emerging trends are proposed, providing some ideas for the development of intelligent wearables.This article is protected by copyright.
