STUDY OF THE VIBRATIONS IN ORDER TO HARVEST LOW-LEVEL ENERGY FROM ROADS Scientists have developed different technologies for generating electricity, but in most cases, this is achieved by using fossil fuels that can have a detrimental effect on human health and the whole ecosystem, which means global warming and changing climatic and biological balances. To avoid this, we must solve the reduction of the use of fossil fuels and find new methods of generating electricity similar to photovoltaic and wind technologies. Piezoelectric energy harvesting technology has significant advantages over other renewable energy sources such as solar or wind. Using the pressure of vehicles over the road caused by gravity, the method generates electric energy from the deformations of the paving. Although recent research projects have paid attention to this energy harvesting technology, only a few studies have been conducted on-site to determine its feasibility and economic competitiveness. No data are available about how this was realized. Therefore, it is necessary to develop a research framework that enables assessment of the technology of piezoelectric materials for this purpose.
