This paper investigates the feasibility of integrating piezoelectric energy harvesting technology into automobile wheels to improve energy efficiency and promote sustainable power generation. By strategically placing piezoelectric sensors around the circumference of the wheel, the rotational motion and pressure from the road are utilized to generate electricity. Through comprehensive analysis and simulations, optimal sensor placement, resonant frequency, and impedance are examined to maximize energy harvesting performance. The study evaluates the power output, current, and voltage at common Indian road speeds of 60 km / h and 80 km / h, considering the efficiency of a charge pump energy harvesting system. The results demonstrate significant potential for power generation, contributing to the development of self-powered automotive systems, and advancing sustainable energy solutions in the automotive industry.
