Due to the increasingly serious environmental pollution and the extreme shortage of energy resources, harvesting clean and sustainable random energy from the environment is a scientific, effective, and necessary solution in the coming intelligent era. Such random and disorder energy, like that from human motion and textile-related movement, can be obtained via textile-based triboelectric nanogenerators (TENGs). However, research related to textile-based TENGs with mature, high-efficiency, and economical manufacturing techniques is limited. Here, by using a high-speed ring spinning method, negative Poisson's ratio yarn (NPRY) with a composite structure is designed and fabricated as a variety of intelligent device. Based on the special negative Poisson's ratio effect, NPRY combined with TENG can be used as a foundation structure to form diverse flexible textile-based electronic devices, such as an energy harvesting fabric, a self-counting yoga elastic band, and a self-powered pre-alarm cable. At the same time, NPRY-TENGs with different structures and structural parameters are systematically investigated to optimize the output performance in this work. This special, low-cost, and highly efficient NPRY as a foundation structure material has promising applications in the manufacture of all kinds of textile-based TENGs and harvesting a lot of random energy from the environment, where the random energy can be used by other electronic devices or those textile-based TENGs themselves as self-powered sensors.

摩擦式纳米发电机可伸缩负泊松比纱线，用于环境能量收集和自供电传感器

由于日益严重的环境污染和能源的极端短缺，在即将到来的智能时代，从环境中收集清洁，可持续的随机能源是科学，有效和必要的解决方案。这样的随机和无序能量，例如来自人类运动和与纺织品相关的运动的能量，可以通过纺织品基摩擦纳米发电机（TENGs）。但是，与具有成熟，高效且经济的制造技术的基于纺织品的TENG相关的研究有限。在这里，通过使用高速环锭纺纱方法，设计并制造了具有复合结构的负泊松比纱线（NPRY），作为各种智能设备。基于特殊的负泊松比效应，NPRY与TENG结合可以用作基础结构，以形成各种柔性的基于纺织品的电子设备，例如能量收集织物，自计数瑜伽松紧带和自供电预警电缆。同时，系统地研究了具有不同结构和结构参数的NPRY-TENG，以优化这项工作的输出性能。这种特殊的低成本
