Piezoelectric actuation technology has been widely used in various precise‐oriented fields. Its notable advantages include high resolution, rapid response speed, output force with high density, and immunity to electromagnetic interference. Characteristics of cross‐scale and multiple‐degree‐of‐freedom (multi‐DOF) output motions are of utmost importance in the context of micro‐/nanopositioning technology. For decades, researchers have been working to develop various piezoelectric devices that exploit these important properties. In this review, a comprehensive review of recent research efforts in the field of cross‐scale multi‐DOF piezoelectric drive technology is provided. To commence, it provides an in‐depth exploration of the unique advantages associated with piezoelectric actuation, demonstrating them through comparative analyses with alternative actuation methods. Subsequently, the complexity of piezoelectric cross‐scale motion is introduced, and the multi‐DOF piezoelectric motion is classified in detail. Furthermore, the practical applications of multi‐DOF cross‐scale piezoelectric actuation technology are systematically elucidated, highlighting its versatility and suitability in real‐world environments. Finally, an in‐depth discussion that addresses the challenges encountered in the field is provided, and the prospective directions for further developments in piezoelectric actuation technology are outlined. This scholarly contribution plays an important role in guiding future research and innovative initiatives.

“…21–23 Three piezoelectric actuators can produce the motions of two rotational axes when they are provided with adequate expansion quantities determined from the kinematic relations. 24,25 On the other side, four actuators can drive the fast steering mirror without coordinate transformation but these are mechanically undefined/indetermined and therefore require extremely high precision and care in manufacturing. 26 .…”

Fast steering mirror, a key component that can compensate for the distortion of the optical axis, plays an essential role in portable spectroscopic sensors. Because the performance of the fast steering mirror has a great influence on the accuracy of the interferometer in the spectroscopic sensor, it is important to verify whether it can satisfy the design requirements by evaluating the performance. In this study, a piezoelectric fast steering mirror with high-resolution and high-speed tilting capability for a portable spectroscopic sensor was fabricated and tested. Design requirements such as steering angle, resolution, and frequency range were set for portable spectroscopic sensors and elastic guide structures actuated by piezoelectric actuators were proposed. Before fabrication, the performances of the proposed fast steering mirror were examined by the finite element method. To verify the proposed fast steering mirror, a prototype was manufactured with a size of 24.5 mm × 24.5 mm × 37.4, including a mirror with a diameter of 20 mm and thickness of 3 mm. This prototype can provide the sufficient convenience for mounting on a spectroscopic sensor for gas monitoring at a distance. Its performance was tested, confirming a steering range of 0.56°, resolution of 1.27 µrad seconds and natural frequency of 282 Hz. In addition, through a performance evaluation test using a visible light laser on an optical test bed, the ability to compensate the tilt error within a few seconds was confirmed for its applicability to actual spectroscopic interferometer products in the future.

This paper develops a moving-magnet electromagnetic actuator for fast steering mirror (FSM). The actuator achieves a reasonable compromise between voice coil actuator and piezoelectric actuator. The stroke of the actuator is between the strokes of a piezoelectric actuator and a voice coil actuator, and its force output is a linear function of air gap and excitation current within our FSM travel range. Additionally, the actuator is more reliable than voice coil actuator as the electrical connection in the actuator is static. Analytically modeling the actuator is difficult and time-consuming. Alternatively, numerous finite element simulations are carried out for the actuator analysis and design. According to the design results, a real prototype of the actuator is fabricated. An experimental test system is then built. Using the test system, the force output of the fabricated actuator is evaluated. The test results validate the actuator analysis and design.
