A new approach in the development of aircraft and aerospace industry is geared toward increasing use of electric systems. An electromechanical (EM) piezoelectric-based system is one of the potential technologies that can produce a compactable system with a fast response and a high power density. However, piezoelectric materials generate a small strain, of around 0.1-0.2% of the original actuator length, limiting their potential in large-scale applications. This paper reviews the potential amplification mechanisms for piezoelectric-based systems targeting aerospace applications. The concepts, structural designs, and operation conditions of each method are summarized and compared. This review aims to provide a good understanding of piezoelectric-based systems toward selecting suitable designs for potential aerospace applications and an outlook for novel designs in the near future.
飞机和航空航天工业发展的一种新方法旨在增加电气系统的使用。基于机电（EM）压电的系统是一种潜在技术，它可以生产出具有快速响应和高功率密度的紧凑型系统。然而，压电材料产生的应变很小，约为原始致动器长度的0.1-0.2%，这限制了它们在大规模应用中的潜力。本文综述了针对航空航天应用的基于压电系统的潜在放大机制。总结并比较了每种方法的概念、结构设计和运行条件。本综述旨在使人们更好地了解基于压电的系统，以便为潜在的航空航天应用选择合适的设计，并展望近期的新颖设计。
