Abstract

Harvesting the mechanical energy dissipated by vehicles passing over road to power micro-electromechanical systems (MEMS) in intelligent transportation systems (ITS) is an important way to realize self-powered traffic condition monitoring. However, the limitations of traditional vehicle energy harvesting speed bumps such as single functionality and heavy-shock on vehicles are not conducive to developing energy harvesting speed bumps for multi-functionalization, versatility and intelligence. In this work, a compact hybridized triboelectric-electromagnetic road energy harvester (CHREH) device is designed. The vehicle's wheels impact force drives the sliding plate movement and triggers the triboelectric generator (TENG) unit and electromagnetic generator (EMG) unit to produce electricity. The enhanced TENG built by multi-layer folded structure is assembled using rGO and surface-patterning modified polydimethylsiloxane (PDMS) composite film. Furthermore, the mechanism and electrical output performance of EMG and TENG are theoretically simulated and experimentally tested. Particularly, TENG unit achieved a peak power of 7.21 mW and the EMG unit reached a peak power of 0.74 mW at an excitation frequency of 5 Hz, in addition to the superior durability. Further, the demonstration of application of self-powered car warning and speed monitoring were conducted. The CHREH offers a feasible approach for self-powered applications deployable to the low power consumption electronic devices and ITS.

用于车速测量的紧凑型三电-电磁混合道路能量收集器

收集车辆通过道路时耗散的机械能，为智能交通系统（ITS）中的微机电系统（MEMS）供电，是实现自供电交通状况监测的重要途径。然而，传统车辆能量收集减速带功能单一、对车辆冲击大等局限性，不利于开发多功能、多用途、智能化的能量收集减速带。在这项工作中，设计了一种紧凑型混合三电-电磁道路能量收集器（CHREH）装置。车辆车轮的冲击力驱动滑动板运动，并触发三电发电机（TENG）单元和电磁发电机（EMG）单元发电。利用 rGO 和表面图案化改性聚二甲基硅氧烷（PDMS）复合膜组装了多层折叠结构的增强型 TENG。此外，还对 EMG 和 TENG 的机理和电输出性能进行了理论模拟和实验测试。其中，在 5 Hz 的激励频率下，TENG 单元的峰值功率达到了 7.21 mW，EMG 单元的峰值功率达到了 0.74 mW，而且耐用性极佳。此外，还进行了自供电汽车预警和速度监测的应用示范。CHREH 为低功耗电子设备和智能交通系统的自供电应用提供了一种可行的方法。
