Recent Advances in Textile‐Based Triboelectric Nanogenerators: From Structural Design to Performance Optimization

ABSTRACT With the escalating global demand for sustainable, wearable electronics and clean energy harvesting technologies, Textile‐based triboelectric nanogenerators (TENGs) have attracted significant attention as a novel energy conversion device. Due to the versatile nature of textile structures, combined with their lightweight, flexible, and wearable characteristics, textiles serve as excellent substrates for TENGs. To promote the in‐depth research and practical applications of textile‐based TENGs, this review classifies them into two main categories based on the dimensional scale of the textile materials: fiber‐based TENGs and fabric‐based TENGs. Further, based on the structural features and weaving techniques of the materials, a more detailed classification is provided, highlighting the unique advantages and limitations of different fiber and fabric structures. This review explores and summarizes the roles and performance differences of these structures in energy harvesting and sensing capabilities, intending to provide a reference for the design optimization and practical application scenarios of smart textile sensor devices.
