可穿戴2D纺织品平台是重点关注的主题，旨在促进在消费电子、能源收集和存储等基于纺织品的应用中创造突出的附加值。尤其是来自人体运动生活环境的2D纺织集能器具有几何变形不足和电流密度低的特点，从而提供低发电量。因此，这项工作的一个独特的起点是使用1D导电束纱线(1D CBY)作为通过编织技术开发基于1D CBY的能量收集器的通用步骤。通过纳米CBY阵列与作为摩擦材料的2D导电织物之间的接触带电，研究了基于一维CBY的摩擦电纳米发电机(1DCBY-TENG)的性能。通过水热过程控制一维CBY表面的层次化纳米结构表面是通过较大的接触表面积提高发电效率的重要途径之一。具有不同1D CBY数目和堆叠配置的1D CBY-TNG也作为简单的集成方案进行了测试，确认了输出性能中预期的1D CBY数目和堆栈依赖关系。
Wearable 2D textile platforms are the subject of intense focus to promote the creation of outstanding added value for textile-based applications in consumer electronics, energy harvesting, and storage. In particular, 2D textile-based energy harvesters from the living environment of human motions exhibit insufficient geometry deformation and low current density, thereby providing low power generation. Therefore, a unique starting point in this work is the use of 1D conductive bundle yarn (1D CBY) as a generic step for the development of 1D CBY-based energy harvesters through a weaving technology. The performance of 1D CBY-based triboelectric nanogenerators (1D CBY-TENGs) is addressed through contact electrification between the arrays of nanostructured 1D CBYs and 2D conductive fabric serving as tribomaterials. The manipulation of hierarchically nanostructured surfaces on the 1D CBYs by the hydrothermal process represents one of the crucial approaches of enhancing power generation through a large contact surface area. The 1D CBY-TENGs with a variation in the number of 1D CBY and stack configurations are also tested as a simple integration scheme, confirming the expected 1D CBY number and stack dependency in the output performance.
