2026-07-03 Research progress and future prospect of micro quasi-solid piezoelectric fan doi:10.57760/sciencedb.j00273.00068 en Micro quasi-solid piezoelectric fan, based on the inverse piezoelectric effect of piezoelectric materials, utilizes high-frequency vibrations of piezoelectric vibrators to drive directional airflow, enabling a quasi-solid-state design without rotating components. Such systems offer advantages including compact structure, low power consumption, low noise, and rapid response, demonstrating broad application prospects in the thermal management of high-density electronic devices within confined spaces. This paper reviews and analyzes the latest research progress and representative products of micro quasi-solid piezoelectric fan, such as cantilever-beam piezoelectric fans, synthetic jet type piezoelectric air pumps, and active cooling chips, developed by major research institutions and related enterprises both domestically and internationally. Key technologies for optimizing the performance of micro quasi-solid piezoelectric fan are discussed, including multi-physics coupling simulation techniques in confined spaces, collaborative design technology of flow rate and back pressure, noise suppression techniques, advanced microscale fabrication technologies, and engineering reliability challenges. Finally, this paper discusses the future development trends of micro quasi-solid piezoelectric fan, including miniaturization, high integration, and coordinated improvement of flow rate and back pressure. micro quasi-solid piezoelectric fan; inverse piezoelectric effect; active cooling chips; thermal management shen gen cai Zhu Xiao Wang Lihao Su Yongquan Xue Wenli Liu Yichen Wu Zhenyu PUBLIC https://creativecommons.org/licenses/by-nc-nd/4.0/ dataset http://www.doi.org/10.3724/jfmd.2605063 Science Data Bank
