Power Generation & Storage System Using Piezoelectric Sensor

The increasing global demand for sustainable and renewable energy sources has led to the exploration of innovative energy harvesting techniques[1] . This paper presents a Footstep Power Generation System utilizing piezoelectric transducers to convert mechanical energy from human footsteps into electrical energy[2].The proposed system consists of an array of piezoelectric sensors embedded in a footstep platform, a unidirectional current controller, an AC ripple filter, a rechargeable battery, and an inverter for energy storage and utilization. When pedestrians walk over the platform, the applied pressure induces electrical charge generation through the piezoelectric effect[6] . The generated energy is conditioned, stored, and utilized to power low-energy electrical appliances such as streetlights, public utilities, and smart city infrastructure[3].
