Abstract Details

2016, Master of Science, University of Akron, Civil Engineering.
In the U.S., there are over 4 million miles (6 million km) of roadways and more than 250 million registered vehicles. The energy lost in the pavement system due to traffic-induced vibration and deformation is enormous. If effectively harvested, such waste energy can serve as an alternative sustainable energy source that can be easily integrated to the transportation system. To harness this forms of energy, the common approach is to utilize a piezoelectric module, which generates electricity when strained. In this thesis, literature review based on different energy harvesting methods has been made. The potential of PVDF, which is a piezoelectric as well as pyroelectric polymer material, is investigated as a potential piezoelectric energy harvester integrated in pavement systems. However, the potential of PVDF as a hybrid piezo-pyroelectric energy harvester has been seldom studied. Through series of well controlled experiments, it is found that there exists interesting coupling phenomenon between piezoelectric and pyroelectric effects of PVDF: the voltage generated by simultaneous mechanical and thermal stimulations is the sum of voltages generated by separate stimulations. In addition, an estimation of power generation through piezoelectric and pyroelectric effect is conducted. The overall effects of temperature on hybrid piezo-pyroelectric energy harvesting piezo and pyro constant varies with temperature are discussed in the end.
