The growing demand for sustainable energy sources has driven researchers to explore innovative energy harvesting techniques. This paper presents a novel mechanical energy harvesting system designed for smart infrastructure applications. The system consists of a spring-loaded mechanism and piezoelectric transducers embedded within a structured model. When pressure is applied, the mechanical force compresses the springs, generating vibrations that activate the piezoelectric discs, producing electrical energy. This harvested energy can be stored in a capacitor or battery and used for low-power applications such as LED lighting, sensor networks, and IoT devices. The integration of a rack and pinion mechanism enhances the displacement, improving energy conversion efficiency. This technology is particularly beneficial for smart infrastructure, industrial floors, transportation systems, and public walkways, contributing to energy efficiency and sustainability. The paper aims utilizing wasted mechanical energy, this system promotes eco-friendly power generation and supports the development of self-sustaining smart infrastructure.
