Abstract
Pavement piezoelectric energy harvesting technique is to use a Piezoelectric Energy Harvester (PEH) to convert the mechanical energy of vehicles into electrical energy. A lot of research has been done on the technology of piezoelectric energy collection, but it is mainly focused on the theoretical model and the laboratory tests and lacks the on-site performance evaluation. In this paper, a stacked array type PEH is designed with protection package, which can improve the performance and the service life of the PEH. The demonstration project is also carried out to test the field performance. It is found that under the actual vehicle loading, the obtained piezoelectric energy can successfully light LED signs.
