Green Energy Harvesting Using Piezoelectric Materials from Bridge Vibrations

Abstract

Piezoelectric energy harvesting from bridge vibrations has attracted many researchers not because it provides a clean and autonomous solution to power portable electronic devices, in addition, it helps in making a smart city. This paper focuses on energy harvesting from low-frequency bridge vibrations which includes vibrations measurements from a city flyover and laboratory experiment using traditional rectifier circuit at low frequency and small amplitude vibrations for storage. The typical practical issues have been addressed associated with PEH from bridge vibrations and electrical circuitry.
