<p>This document highlighted a new approach to optimizing the cost-effectiveness of piezoelectric energy harvesting systems. The proposed method achieved the two fundamental objectives of (i) maximizing energy harvesting efficiency through optimal energy transfer to storage systems, and (ii) ensuring system stability and reliability under various mechanical stresses. For this purpose, an intelligent control algorithm has been implemented and integrated into the storage and energy management components. Further proof of concept was provided by the design and implementation of a prototype Spartan-6 board, taking advantage of advanced prototyping platforms for real-time operation and precise control. Furthermore, a comprehensive analysis, including formal evaluations, simulations and experimental tests, confirmed the system's effectiveness in improving energy harvesting performance and maintaining constant operational stability, making it a promising solution for sustainable energy applications.</p>
