Abstract: The increasing demand for renewable and sustainable energy sources has encouraged the development of innovative energy harvesting technologies. Footstep energy harvesting is a promising method that converts mechanical energy generated by human walking into electrical energy. This work presents the design and implementation of a piezoelectric-based footstep power generation system capable of producing electrical energy from pedestrian movement. In the proposed system, multiple piezoelectric sensors are installed beneath a footstep platform where they experience mechanical stress whenever a person steps on the surface. Due to the piezoelectric effect, the applied pressure produces electrical voltage that can be collected and processed. The generated electrical output is passed through a rectifier and voltage regulation circuit to convert it into stable DC power suitable for storage. The conditioned energy is stored in a rechargeable battery and later utilized for practical applications. The stored power is used for automated street lighting and an RFID-based charging station that allows authorized users to charge small electronic devices.
