Abstract

Marine pipeline vibration condition monitoring is a critical and challenging issue, on account of the complex marine environment, while powering the required monitoring sensors remains problematic. This study introduces a vibration sensor based on a ball triboelectric nanogenerator (B-TENG) for marine pipelines condition monitoring. The B-TENG consists of an acrylic cube, polyester rope, aluminum electrodes, and PTFE ball, which converts vibration signals into electrical signals without the need for an external energy supply. The experimental results show that B-TENG can accurately monitor the frequency, amplitude, and direction of vibration in the range of 1-5 Hz with a small error of 0.67%, 4.4%, and 5%, and an accuracy of 0.1 Hz, 0.97 V/mm, and 1.5°, respectively. The hermetically sealed B-TENG can monitor vibration in underwater environments. Therefore, the B-TENG can be used as a cost-effective, self-powered, highly accurate vibration sensor for marine pipeline monitoring.

摘要

由于海洋环境复杂，为所需的监测传感器供电仍然存在问题，因此海洋管道振动状态监测是一个关键且具有挑战性的问题。本研究介绍了一种基于球形摩擦纳米发电机（B-TENG）的振动传感器，用于海洋管道状态监测。B-TENG由一个丙烯酸立方体、聚酯绳、铝电极和聚四氟乙烯球组成，无需外部能源供应即可将振动信号转换为电信号。实验结果表明，B-TENG能够在1-5Hz范围内准确监测振动的频率、幅度和方向，误差分别为0.67%、4.4%和5%，精度分别为0.1Hz、0.97V/mm和1.5°。密封的B-TENG可以在水下环境中监测振动。因此，B-TENG可作为一种经济高效、自供电、高精度的振动传感器用于海洋管道监测。
