The triboelectric material properties and mechanical stability of the contact layer are vital to achieving durable triboelectric nanogenerators (TENGs) with high output performance. Herein, a novel MXene/Ecoflex nanocomposite is introduced as a promising triboelectric material because of its highly negative triboelectric properties and mechanical stability. The MXene/Ecoflex nanocomposite with a fabric‐based waterproof TENG (FW‐TENG) is fabricated and designed to universally harvest energy from various human motions as well as the natural environment (rain and wind). The fabricated FW‐TENG delivers a maximum output peak power of 3.69 mW and a power density of 9.24 W m⁻², respectively, at a matching load resistance of 4.5 MΩ under a frequency of 4.5 Hz and a force of 8 N. Furthermore, the applicability of this device in various products is investigated. The FW‐TENG can protect against a crash caused by rainy and humid weather. An FW‐TENG‐based self‐powered smart active device that detects motion on a carpet is demonstrated and is equipped with sleep monitoring motion sensors. The FW‐TENG not only has self‐powered benefits and excellent mechanical amenability but is also exceptionally reliable and stable against water intrusion, which are important characteristics to realize next‐generation wearable/portable technologies.

一种新颖的MXene / Ecoflex纳米复合涂层织物，可作为高负摩擦和稳定的摩擦层，适用于高输出摩擦电纳米发电机

接触层的摩擦电材料特性和机械稳定性对于获得具有高输出性能的耐用摩擦电纳米发电机（TENG）至关重要。本文中，由于其极高的负摩擦电性能和机械稳定性，因此引入了新颖的MXene / Ecoflex纳米复合材料作为一种有前途的摩擦电材料。MXene / Ecoflex纳米复合材料具有基于织物的防水TENG（FW-TENG），其制造和设计旨在从各种人体运动以及自然环境（雨水和风）中普遍收集能量。制成的FW-TENG的最大输出峰值功率为3.69 mW，功率密度为9.24 W m ^-2分别在4.5 Hz的频率和8 N的力下在4.5MΩ的匹配负载电阻下。此外，还研究了该器件在各种产品中的适用性。FW-TENG可以防止雨天和潮湿天气导致的撞车事故。演示了一种基于FW-TENG的自供电智能主动设备，该设备可检测地毯上的运动并配备有睡眠监控运动传感器。FW-TENG不仅具有自供电优势和出色的机械适应性，而且还具有出色的可靠性和稳定的防水性能，这是实现下一代可穿戴/便携式技术的重要特征。
