“…Actuator technologies have received strong attention in robotics system research, micro-electromechanical system research, and bio-engineering applications [34,35]. In robotics applications, typical actuators are: (i) direct and geared drive motors, (ii) electromechanical grabbing hands, (iii) hydraulic and pneumatic arms, (iv) piezoelectric and magnetostrictive actuators, and (v) shape memory and contractile polymer actuators [36,37].…”

“…In general, piezoelectric materials have a very small strain, of 0.1–0.2%, but with high stress, in the range of 100–131 MPa. Their specific power density is around 1000 kW/kg, and they have high efficiency, of more than 80% [ 40 , 43 , 58 ]. However, piezoelectric materials experience some drawbacks, such as substantial hysteresis [ 59 ], temperature-dependent properties [ 60 ], and fracture behaviors [ 61 ].…”

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.
