HYBRID MOBILE CHARGING SYSTEM USING PIEZOELECTRIC ENERGY HARVESTING

Abstract

This project introduces an advanced energy harvesting and mobile charging system utilizing piezoelectric materials with IOT integration. By converting mechanical energy—such as footsteps or vibrations—into electrical power, the system enables efficient energy storage and utilization. The harvested energy is stored in a 12V battery, regulated by a charge controller, and monitored through voltage sensors. An LCD provides real-time system data visualization, while a NodeMCU-based IOT module allows users to remotely track power generation and optimize device charging. This innovative solution enhances energy efficiency, promotes sustainability, and supports smart power management for portable applications, addressing energy scarcity while integrating intelligent monitoring capabilities.
