The importance of ocean exploration and underwater monitoring is becoming vital, due to the abundant biological, mineral, energy, and other resources in the ocean. Here, a self-powered underwater cable-based triboelectric nanogenerator (TENG) is demonstrated for underwater monitoring of mechanical motion/triggering, as well as searching and rescuing in the sea. Using a novel double-layer winding method combined with ferroelectric polarization, a self-powered cable-structured sensor with a stable electrical output has been manufactured, which can accurately respond to a variety of external mechanical stimuli. A self-powered cable sensing network woven using smart cables can comprehensively transmit information, such as the plane position and dive depth of a submersible. More precisely, it can analyze its direction of movement, speed, and path, along with transmitting information such as the submersible's size and momentum. The developed self-powered sensor based on the cable-based TENG not only has low cost and simple structure but also exhibits working accuracy and stability. Finally, the proposed work provides new ideas for future seabed exploration and ocean monitoring.
由于海洋中丰富的生物、矿物、能源和其他资源，海洋探索和水下监测的重要性日益凸显。在此，展示了一种基于自供电水下电缆的摩擦纳米发电机（TENG），用于水下机械运动/触发监测以及海上搜索和救援。采用一种结合铁电极化的新型双层缠绕方法，制造出了一种具有稳定电输出的自供电电缆结构传感器，它能够准确响应各种外部机械刺激。使用智能电缆编织而成的自供电电缆传感网络可以全面传输诸如潜水器的平面位置和潜水深度等信息。更精确地说，它可以分析其运动方向、速度和路径，同时传输潜水器的尺寸和动量等信息。所开发的基于电缆TENG的自供电传感器不仅成本低、结构简单，而且具有工作精度和稳定性。最后，所提出的工作为未来的海底探索和海洋监测提供了新思路。
