“…In the structural designs of FHMs-PSSAs, the asymmetric structure is usually adopted to obtain greater load capacity and speed, but the inconsistent forward and reverse output performance is further amplified (Shao et al, 2020). From the previously published articles, the FHMs-PSSAs designed by a single piezoelectric stack only showed the output performance in either forward or reverse direction in most cases (Cheng et al, 2017a;Gao et al, 2019aGao et al, , 2019bHuang and Sun, 2019;Li et al, 2015cLi et al, , 2020aLi et al, , 2020bLi et al, , 2020cLu et al, 2020b;Wan et al, 2020;Zhang et al, 2019aZhang et al, , 2020. To improve the consistency of FHMs-PSSAs forward and reverse performance, some FHMs-PSSAs adopted the structural design that two asymmetric stators were directly connected in parallel type (Huang et al, 2020;Li et al, 2017aLi et al, , 2018aWang et al, 2019a;Yang et al, 2020b) or in series type (Huang et al, 2012) on the mechanical mechanism; however, due to the normal pressure between the two driving feet and the slider, the other stationary driving foot adversely affected the driving performance as one driving foot was driving.…”

“…Besides, some other mechanisms could be regarded as extensions of the lever mechanism, such as parallelogram type (see Figure 5(d)) (Li et al, 2015c), rhombus type (see Figure 5(e)) (Gao et al, 2019b), triangular type (see Figure 5(g)) (Lu et al, 2020b), etc. (Li et al, 2020a, 2020b; Wan et al, 2020). As shown in Figure 5(b), in the research of trapezoid-type FHMs-PSSA designed by Cheng et al, they found that the normal pressure between the driving foot and the slider could be switched; through the structural design, the static friction in the slow elongation phase could be increased and the dynamic friction in the rapid contraction phase could be reduced (Cheng et al, 2017a).…”

Piezoelectric stick-slip actuators (PSSAs) are famous for ultimate working condition adaptability, simple structure, and positioning accuracy. To meet the demand of industrial application, lots of PSSAs designed with flexure hinge mechanisms (FHMs-PSSAs) have been developed to realize the requirements of translational motion, rotational motion, multi-degree-of-freedom (multi-DOF) motion. The output performance of the FHMs-PSSAs has been greatly improved, including load capacity, speed, and accuracy; moreover, some approaches to solve the problem of the backward motion are provided as well. In this work, the working principle of FHMs-PSSAs is introduced, and the excitation signals applicable to FHMs-PSSAs are summarized. Based on the current research and development status, the progress of structure design of FHMs-PSSAs is introduced in accordance with translatory FHMs-PSSAs, rotary FHMs-PSSAs, and multi-DOF FHMs-PSSAs. Additionally, the developed analysis methods and design schemes to improve the performance are introduced, including theoretical analysis methods, consistency scheme of forward and reverse performance, suppression scheme of the backward motion, and improvement scheme of positioning accuracy. The significance of this work can be regarded as a further supplement to the previous review articles on the PSSAs, which will provide a reference and guidance for the future development of FHMs-PSSAs.

“…The clamping unit and the driving unit both include a flexure mechanism, a PZT stack, and a wedge block. The asymmetrical trapezoid flexure mechanism is utilized for the coupled driving unit to achieve the motion both in x and y directions, so as to push the slider to move [25]. In addition, the rectangle flexure mechanism is applied for the clamping unit to clamp or release the slider according to the control signal.…”

A novel bionic piezoelectric actuator based on the walrus motion to achieve high performance on large working stroke for micro/nano positioning systems is first proposed in this study. The structure of the proposed walrus type piezoelectric actuator is described, and its motion principle is presented in details. An experimental system is set up to verify its feasibility and explore its working performances. Experimental results indicate that the proposed walrus type piezoelectric actuator could realize large working stroke with only one driving unit and one coupled clamping unit; the maximum stepping displacement is ΔLmax = 19.5 μm in the case that the frequency f = 1 Hz and the voltage U = 120 V; the maximum speed Vmax = 2275.2 μm · s−1 when the frequency f = 900 Hz and the voltage U = 120 V; the maximum vertical load mmax = 350 g while the voltage U = 120 V and the frequency f = 1 Hz. This study shows the feasibility of mimicking the bionic motion of the real walrus animal to the design of piezoelectric actuators, which is hopeful for the real application of micro/nano positioning systems to achieve large working stroke and high performance.

“…A parallelogram-type compliant mechanism based PMP actuator was studied in the literature of [23]. Trapezoid [24,25] and triangular [26] compliant mechanisms were also employed in the design of the PMP actuators. Apart from that, the PMP actuators were widely studied based on other different structures such as Z-shaped [27], L-shaped [28], X-shaped [29], arc-shaped [30] etc.…”

To meet the demand of designing piezoelectric actuators with long working stroke and high resolution, a new parasitic motion principle (PMP) linear actuator based on the symmetrical Z-shaped compliant mechanism was proposed in this paper. The mechanism design and the operation principle of the proposed linear actuator were elaborated. The theoretical model of the symmetrical Z shaped compliant mechanism deformation was established, and was verified by the simulation analysis. Experimental studies were conducted on a manufactured prototype to investigate the performances of the proposed linear actuator. The results indicate that a linear actuator with bi-directional motion can be achieved, which has a resolution of 106 nm in the forward direction and 84 nm in the reverse direction. Under the locking force of 0.8 N, the maximum speed of 270 µm s−1 was reached, when the amplitude and the frequency of the driving voltage were set to 60 V and 650 Hz. It is also noted that the proposed linear actuator can work with a loading capacity of 25 g. This study has provided an alternative way for the development of a PMP linear actuator with bi-directional motion.
