Abstract

Based on the solid-liquid friction nanogenerator (TENG) technology, a sensor capable of monitoring flange leakage was studied and developed. It was composed of polytetrafluoroethylene (PTFE) dielectric material and metal electrodes, and the output performance under different conditions was studied by experiments to determine the sensor configuration and monitoring parameter design. In order to achieve the visualization of leakage monitoring signal transmission and alarm, a single-chip microcomputer circuit board adapted to sensors was developed, which can collect leakage signals and send to the terminal leakage alarm unit developed by using LabVIEW program through wireless transmission, achieving real-time monitoring of ship flange leakage.
