Abstract
This research and development project investigates the feasibility and practical potential of converting sound energy from diverse sources into electrical energy. This study focuses on a specially designed system that integrates in-house designed components mergeed with piezoelectric materials to optimize sound wave absorption and conversion efficiency.
Inspired by the intricate design of the human inner ear, the system aims to maximize sound energy capture and enhance the conversion rate using piezoelectric materials. The framework encapsulates the dynamics of sound waves, considering both kinetic and potential energy components. Advanced analytical methods model the energy transformation process providing high accuracy and applicability. Lagrange's equations derive the governing equations of motion for the piezoelectric materials, analyzed using the method of multiple scales, extending to third-order approximations for precision in the theoretical model.
Empirical analyses through simulations demonstrate the operational dynamics under variable acoustic conditions, assessing energy conversion efficiency across different sound intensities and frequencies. Results include detailed graphical representations, such as time history plots and phase portraits.
The implications of this research are aimed towards building low-energy devices that help provide sustainable solutions for renewable energy in noise-polluted urban environments.
