This article addresses the method of sensing mechanical quantities, in particular force and pressure, without the electrical connection of the sensing element and the electronics. The information about the mechanical quantity is transmitted only by evaluating the changes in the electromagnetic field created around the sensor. The sensor is designed on the basis of a flexible micro-electro-mechanical element (MEMS), the resonance of which carries the information about the measured quantity.

“…They are used to press and drive the slider, respectively. Thus, the flexure hinges with special structures are frequently adopted in the designs (Wang et al, 2017; Wei et al, 2018; Zhang et al, 2019; Zhong et al, 2019). For instance, Xu et al (2020) proposed a piezoelectric stick-slip actuator using a lever type flexure hinge.…”

A new piezoelectric stick-slip actuator using stair type flexure hinge is proposed and developed in this work. It’s spirited by referencing the reported “Z-shaped” flexure hinge in the literatures and the idea of asymmetric structure. In this design, the PZT stack can generate elongation displacement under the excitation of sawtooth signal, and then the elongation can be transmitted into the vertical and horizontal displacements on the driving tip by the stair type flexure hinge. The slider is pressed by the vertical displacement and driven by the horizontal displacement, respectively. The working principle of the proposed actuator is clarified. The statics characteristics are investigated by the theoretical and simulation methods. Finally, the mechanical output characteristics of the developed prototype are tested. The maximum output velocity is 8.5 mm/s when the voltage and frequency are 100 V and 720 Hz. The maximum output force is tested as 2.6 N when the preloading force is 3 N. The experiment results validate the feasibility of the proposed piezoelectric stick-slip actuator based on stair type flexure hinge.

In the field of piezoelectric actuators, high speed piezoelectric stick-slip actuators have received considerable attention. A linear stick-slip piezoelectric actuator is proposed in this article, which combines asymmetric flexure hinge with triangular displacement amplification mechanism. The designed linear piezoelectric stick-slip actuator can achieve high speed at lower frequency. The configuration of the actuator and driving principle are illustrated and designed by theory and simulation. In order to study its performance, a prototype is fabricated, and an experimental system is established. The experimental results confirm that the maximum step efficiency of the prototype is 97.9 %. The maximum speed is 20.17 mm/s under the driving voltage of 100 V P−P , the driving frequency of 610 Hz and the locking force of 2.5 N. The maximum load capacity is 2.4 N under the locking force of 3.5 N. The proposed piezoelectric stick-slip actuator increases the step efficiency and improves the output speed at lower frequency. INDEX TERMS High speed, stick-slip actuators, asymmetric flexure hinge, triangular displacement amplification mechanism.
