Wearable energy harvesters (WEHs) have garnered significant attention recently due to their promising capabilities in powering wearable devices. In this research, we present a core–shell yarn-structured triboelectric nanogenerator (CY-TENG) that operates in two modes: the single-electrode TENG (SE-TENG) and the droplet-based electricity generator. This design facilitates energy harvesting from both waterdrops and biomechanics. The CY-TENG is fabricated using fluorinated ethylene propylene ultrafine heat-shrink tubes combined with stainless-steel yarns, ensuring its flexibility, durability, and weavability. Such attributes underscore its potential as a dual-function WEH.

用于收集水滴和生物力学能量的核壳纱线结构摩擦纳米发电机

可穿戴能量采集器（WEH）因其在为可穿戴设备供电方面的前景广阔的能力而最近引起了广泛关注。在这项研究中，我们提出了一种核壳纱线结构摩擦纳米发电机（CY-TENG），它以两种模式运行：单电极TENG（SE-TENG）和基于液滴的发电机。这种设计有利于从水滴和生物力学中收集能量。 CY-TENG采用氟化乙烯丙烯超细热缩管与不锈钢纱线结合制成，确保其灵活性、耐用性和可编织性。这些属性凸显了其作为双功能 WEH 的潜力。
