In order to ensure self-maintenance of roads, solar energy, wind energy, heat energy and mechanical energy in the environment are gradually collected and utilized and converted into electric energy. However, in the field of energy conversion in road engineering, the collection of solar energy, thermal energy and wind energy, except for mechanical energy, is susceptible to the influence and interference of environmental factors, and the conversion efficiency is not easy to guarantee. In addition, the road environment is one of the most enriched places of mechanical energy, and energy conversion methods based on electromagnetic induction, piezoelectric effect and pyroelectric have been widely adopted, but all of them have the defects of low energy conversion efficiency, narrow frequency band, excessive signal sensitivity, and the like.
