The increasing demand for energy resulting from technological and social development encourages the search for alternative methods of energy harvesting. This work presents a concept of utilizing airflow to power low-energy measurement and monitoring systems. The proposed system uses piezoelectric transducers to recover energy from mechanical vibrations induced by air movement. Two cylindrical elements mounted on flexible beams are subjected to airflow, causing them to oscillate. The deflection of the beams generates electrical energy through piezoelectric elements. A numerical model has been developed to analyze the system’s performance, followed by experimental verification using wind tunnel tests. The main objective is to create an efficient and robust energy harvesting solution capable of operating under variable wind conditions. The results contribute to the development of autonomous power sources for distributed sensor networks.
