Energy harvesting technology is an important way to develop green intelligent transportation system. In contrast to battery and cable power supply, mechanical energy collected from the traffic environment and converted into electrical energy can be used to power MEMS distributed in intelligent transportation systems. And this kind of electricity has the advantages of convenient, sustainable, green and lowcarbon.In this paper, a hybrid triboelectricelectromagnetic energy harvesting bump is designed. The device is mainly composed of an electromagnetic generator unit and a triboelectric generator unit. The device 's electromagnetic power generation unit magnet coils are staggered so as to improve space utilization and power density. The triboelectric unit uses a modified polydimethylsiloxane composite film with folded structure, which can significantly increase the output power. The magnetic and elastic dual force reset design can avoid the shortcomings of traditional spring return requiring precision guiding mechanism. Based on the working principle of hybrid energy harvesting bump, the electromechanical coupling dynamic model is established and verified by experiments. The results show that the maximum average power generated by the left and right tribological generating units is 353.1 μW and 360μW respectively, and the average power generated by electromagnetic generation is 6.67 μW under the excitation frequency of 5 Hz and the force of 15 N. The device collects vehicle rolling energy and provides sustainable green carbonfree power for small devices in the traffic environment.
