面向交通自供能监测的低频适应型摩擦电装置设计与测试
Design and Testing of Low-frequency-driven Rotary Triboelectric Nanogenerator for Self-powered Traffic Monitoring
摘要
Abstract
To address the issues of strong dependence on mains electricity and poor deployment flexibility of conventional traffic monitoring devices,a low-frequency-driven rotary triboelectric nanogenerator(LDR-TENG)adapted to low-frequency,transient,and intermittent excitations was designed.Centered on a rotary triboelectric structure,a rack-pinion-mainspring-spring composite transmission system was constructed to convert transient vertical loads into sustained rotational excitations,thereby enhancing the energy harvesting and signal stability.Test results show that stable periodic signals can be generated at loading speeds as low as 5 mm·min−1,with voltage characteristics linearly correlated to the loading speed(R²=0.998 87).LDR-TENG was further embedded in an intelligent road stud for field testing,where the measured voltage features exhibited a 97.92%correlation with vehicle speed.A single-lane deployment scheme based on wheel track distribution achieved a vehicle trigger coverage rate of 76.47%.关键词
