船舶姿态信息对于船舶航行安全、货物装卸监控和作业管理具有重要意义。因此，迫切需要研制一种能够在恶劣环境下工作的机电一体化倾角传感器。本文提出并系统研究了一种基于环形液固界面摩擦电纳米发电机（TENG）的自供电倾角传感器。TENG倾角传感器由一个表面带有铜电极段的聚四氟乙烯（PTFE）环形管和内部无气泡封装在PTFE管中的液体组成。为合理设计TENG传感器结构，提高其灵敏度，对电极宽度和液体类型进行了研究。通过耐久性测试，TENG倾角传感器在低频、低振幅的倾斜条件下具有稳定的输出性能和高灵敏度特性。此外，TENG倾角传感器内部没有运动部件，几乎不会因部件磨损而失效。在高湿度、高盐度、强磁场等恶劣环境下，也能充分发挥其耐用性、免维护性、与外界环境无关的优势。因此，本课题研制的TENG倾角传感器对提高船舶的自动化和智能化水平具有重要的现实意义。(C)2020爱思唯尔B.V.保留所有权利。
Ship's attitude information is of great significance for navigation safety, cargo handling monitoring, and operation management. It is highly desired to develop an electromechanical integrated tilt sensor which can work well under harsh environment. In this paper, a robust and self-powered tilt sensor based on annular liquid-solid interfacing triboelectric nanogenerator (TENG) is to be proposed and systematically investigated. The TENG tilt sensor is composed of an annular polytetrafluoroethylene (PTFE) tube with copper electrodes segment disposed on the surface and the internal liquid which is encapsulated in PTFE tube with no air bubble. Studies on electrode width and liquid type are conducted to reasonably design the TENG sensor structure and improve its sensitivity. By conducting the durability test, the TENG tilt sensor demonstrates stable output performance and high sensitivity characteristics in low-frequency and low-amplitude inclination conditions. Moreover, the TENG tilt sensor hardly fails due to parts wear since there are no moving parts in it. The advantage of durability, maintenance-free, and independent with the external environment are highlighted in a harsh environment with high humidity, high salinity and strong magnetic field. Therefore, the present TENG tilt sensor is of practical significance for improving the automation and intelligence of ships. (C) 2020 Elsevier B.V. All rights reserved.
