In this study, we introduced an integrated approach using piezoelectric thin film-based surface acoustic wave (SAW) and wireless power transfer (WPT) technologies, designed for both passive monitoring and active defogging/icing functions. We systematically investigated the resonant frequency shifts of ZnO/glass SAW devices, establishing their correlations with variations in humidity and temperature under cold conditions. Acoustic waves generated through the ZnO/glass SAW device were used for defogging and deicing functions with effects of RF powers and acousto-heating thoroughly evaluated. More significantly, the WPT system was successfully applied for achieving defogging and deicing functions, with its performance comparable to that of conventional wired SAW systems. Our findings demonstrated that the WPT SAW system significantly minimizes localized acousto-heating effects, although the time taken for both defogging and deicing was slightly longer than the wired system. This work represents a significant advancement in developing multifunctional, optically compatible, and wireless-integrated solutions for SAW based ice protection.
在本研究中，我们引入了一种集成方法，该方法采用基于压电薄膜的表面声波（SAW）和无线电力传输（WPT）技术，旨在实现被动监测以及主动除雾/除冰功能。我们系统地研究了ZnO/玻璃SAW器件的共振频率偏移，确定了它们与寒冷条件下湿度和温度变化的相关性。通过ZnO/玻璃SAW器件产生的声波用于除雾和除冰功能，并对射频功率和声致热效应进行了全面评估。更重要的是，WPT系统成功应用于实现除雾和除冰功能，其性能与传统有线SAW系统相当。我们的研究结果表明，WPT SAW系统显著降低了局部声致热效应，尽管除雾和除冰所需的时间比有线系统略长。这项工作代表了在为基于SAW的冰保护开发多功能、光学兼容和无线集成解决方案方面的重大进展。
