    Abstract: Microsystem application techniques have been considered increasingly vital in the development of modern science and technology. Modern industries, such as microelectromechanical systems (MEMS), opto-electronics, and the semiconductor industry, require the assistance of microactuators, which have a wide range of applications in everyday life, such as the zoom function in cell phones or cameras, precision positioning platforms, microvehicles, microinjections, and beauty and health care products. Microactuators are generally categorized into electromagnetic actuators and piezoelectric actuators. Electromagnetic actuators feature complex structures and large sizes, and are easily affected by electromagnetic fields, thereby limiting their application scope. Comparatively, piezoelectric actuators can replace electromagnetic actuators in numerous instances because of various advantages, such as high accuracy, low power consumption, simple structure, increased strength, and resistance to electromagnetic field disturbances. By using finite element analysis software, this study simulated the vibration mode and amplitude of piezoelectric actuators. The Taguchi method was used to design the parameters of piezoelectric actuators containing double pushers. Finally, this paper presents a discussion regarding the influence that the design parameters had on the actuator amplitudes. Based on optimal design parameters, this study produced a piezoelectric actuator containing double pushers and tested the thrust force, confirming that actuators containing double pushers provide a greater thrust force than that of traditional actuators possessing a single pusher.
