Design and Implementation of a Prototype of Piezo Transduced Intelligent Power Management System for Efficient Street Lighting

To meet the ever-growing demand of this power hungry world, wasted energy can play a significant role.Wasted energy is the one which is not used in any part of a transferred or transformed process.Footstep energy is such a type that can be utilized properly in potential areas like crowded places.Every time people walk, a system captures this energy as pressure or stress and then converts it into electrical energy.This paper presents the design of a prototype of pressure transduced intelligent power management system for the street lighting system that can be self-enabled automatically from dawn to dusk.A way of avoiding the risk of battery damage is introduced in this design.A priority based power connection scheme is also shown to make an effective power management system for this system.The output results are also in accord with the design scheme that indicate almost linear relationships between stress in piezo transducers and voltage or power produced from it.
