Power generation for auto street light using PZT

Abstract

Energy consumption is an indicator of development of the universe. Modern world needs a huge amount of electrical power to meet up the current demand whereas the resources of conventional energy sources are diminishing steadily in response of vast consumption of energy. So, alternate sources of energy are required not only to fill up the large gap between demand and supply of electricity but also they should be clean, environment friendly and sustainable. This research work is based on the piezoelectric effect in which certain materials have the ability to build up an electrical charge from having pressure and strain applied to them. This research paper focused on the applications of auto street light for transportation facilities using that energy. When the roads or the tires of vehicle are engineered with piezoelectric technology, the energy produced by the pressure of moving vehicles is captured by piezo sensors and converted it into electrical charge by Lead Zirconium Titanate as a Piezoelectric Transducer (PZT), then stored the energy and used as an energy generation source. This energy source can be used for auto street lighting as a source of roadside power generation unit. In this research work, generated voltage and current depend on the system configuration of PZT, stress on the PZT, displacement of PZT from its original state and the way of connection of PZT plates.
