Abstract

Triboelectric nanogenerators (TENGs) have gained significant attention in recent years, yet challenges such as limited output power and unidirectional energy harvesting persist in conventional designs. To address these issues, this study introduces a dual-mode stretchable and rotatable TENG (SR-TENG). The SR-TENG operates in two modes: vertical contact separation and rotational contact separation. The base of the structure is made of origami technology, and the material is environmentally friendly cowhide paper. The positive and negative electrode materials of SR-TENG are nylon and micropatterned PDMS films (G-PDMS), respectively. It is worth noting that its performance is significantly improved over the traditional TENG, and it has a high output performance in both modes. Additionally, an arm motion monitoring system integrating with the SR-TENG enabled real-time motion monitoring. This creative design not only enhances output performance but also enables multidirectional energy harvesting, expanding its potential for sustainable energy and intelligent applications.

用于手臂运动检测的柔性双模可拉伸可旋转摩擦电纳米发电机

摩擦电纳米发电机（TENGs）近年来获得了广泛的关注，但传统的设计仍然存在诸如有限的输出功率和单向能量收集等挑战。为了解决这些问题，本研究引入了一种双模可伸缩可旋转TENG （SR-TENG）。SR-TENG有两种工作模式：垂直接触分离和旋转接触分离。该结构的底座采用折纸技术，材料为环保牛皮纸。SR-TENG的正极材料为尼龙，负极材料为微图纹PDMS薄膜（G-PDMS）。值得注意的是，它的性能比传统的TENG有了显著的提高，并且在两种模式下都有很高的输出性能。此外，一个与SR-TENG集成的手臂运动监测系统使实时运动监测成为可能。这种创造性的设计不仅提高了输出性能，而且实现了多向能量收集，扩大了其可持续能源和智能应用的潜力。
