摘要: The transportation infrastructures serve a critical societal need to rapidly move goods and people across the nation. Using these as source of renewable energy by harvesting them from roadways is novel idea that has not been fully explored yet. Highway pavements are exposed energy-potential resources vehicle vibrations traffic loading strains. Energy process captures unused ambient such heat, vibration, stress or movement would otherwise be lost. Piezoelectric transducers considered materials for in pavement structures they convert mechanical strain into low voltage. For this purpose, two types piezoelectric geometry were evaluated; cylindrical disks thin film, suitable compression bending state stresses, respectively. Two prototypes including connected series parallel evaluated study effect frequency magnitude on output power under compression. Another prototype containing film was developed investigate potential condition. Finite element (FE) analysis conducted simulate prototypes’ response loading. evaluation involves laboratory testing their function FE simulation behavior. results showed modules should designed capture vertical compressive instead tensile stress. Results suggested voltage highly dependent magnitude. It also concluded stack produces higher current similar conditions.
