Abstract

In recent years, triboelectric nanogenerators (TENGs) have garnered extensive attention in the realm of self-powered sensors due to their capability to harness low-frequency mechanical energy. Among these, textile-based triboelectric nanogenerator stands out as a pivotal platform for wearable sensing. Nevertheless, conventional approaches, such as directly coating triboelectric materials on fabrics, often compromise the inherent properties. In this study, we utilized our self-developed electro-centrifugal spinning equipment to continuously fabricate core-sheath yarns with micro/nano structures, resulting in the development of pocket-shaped fabric-based (PF) TENGs. This innovative design preserves the original softness and breathability of the fabric while delivering substantial electrical output owing to its layered structure and extensive specific surface area. PF–TENGs can accurately detect electrical output signals from various motion states. This electro–centrifugal spinning technology offers new research directions and sensing application prospects for self-powered smart textile development.

电离心纺制具有微米/纳米结构的自供电传感芯鞘复合纱线

近年来，三电纳米发电机（TENGs）因其利用低频机械能的能力而在自供电传感器领域受到广泛关注。其中，基于纺织品的三电纳米发电机是可穿戴传感的关键平台。然而，传统的方法，如在织物上直接涂覆三电材料，往往会影响其固有特性。在这项研究中，我们利用自主研发的电动离心纺纱设备，连续制造出具有微/纳米结构的芯鞘纱线，从而开发出袋状织物型 (PF) TENG。这种创新设计保留了织物原有的柔软性和透气性，同时由于其分层结构和广泛的比表面积，可提供大量的电输出。PF-TENG 可以准确检测各种运动状态下的电输出信号。这种电离心纺纱技术为自供电智能纺织品的开发提供了新的研究方向和传感应用前景。

期刊介绍： Composites Communications (Compos. Commun.) is a peer-reviewed journal publishing short communications and letters on the latest advances in composites science and technology. With a rapid review and publication process, its goal is to disseminate new knowledge promptly within the composites community. The journal welcomes manuscripts presenting creative concepts and new findings in design, state-of-the-art approaches in processing, synthesis, characterization, and mechanics modeling. In addition to traditional fiber-/particulate-reinforced engineering composites, it encourages submissions on composites with exceptional physical, mechanical, and fracture properties, as well as those with unique functions and significant application potential. This includes biomimetic and bio-inspired composites for biomedical applications, functional nano-composites for thermal management and energy applications, and composites designed for extreme service environments.
