With the development of moon exploration, higher requirements have been proposed for the adaptability of small motors under vacuum and micro-dust conditions. In this paper, a rotational motor based on piezoelectric stacks is proposed, which can be driven by a single-phase direct current with a simple drive circuit. The motor dimensions are 24 mm × 24 mm × 24 mm (length × width × height), and the mass is 11.4 g. In air environment, the maximum output rotational speed of the motor is 1372 rpm, and the maximum stall torque is 3.2 mN·m at 40 VDC and 5.93 kHz. An open-loop control system is established to drive the stepping motion of the motor, and the minimum stepping angle is measured as 0.122 mrad. An environmental experiment of the motor is conducted in a lunar simulator module, which can simulate a high vacuum (6.7 × 10-5 Pa) and micro-dust (average 75 μm) environment of the lunar surface. The result shows that the motor can work steadily in the vacuum and micro-dust environment with an average speed of 1723 rpm, which demonstrates its potential applications in the space environment.

“…Yoseph Bar-Cohen et al proposed a rotating piezoelectric actuator comprising 12 CMPCs, which is capable of operating at a lower driving voltage and exhibits a higher power density [ 25 ]. In addition, Wen Zhiyi et al developed an in-plane traveling wave rotating piezoelectric actuator driven by CMPCs, which can operate smoothly at a driving voltage of 5 V p-p [ 26 ]. Therefore, CMPCs can replace piezo tubes or piezoelectric bimorphs in conventional resonant fiber optic scanners to achieve the miniaturization and low-voltage drive requirements of the optical scanners.…”

Piezo-driven resonant fiber optic scanners are gaining more and more attention due to their simple structure, weak electromagnetic radiation, and non-friction loss. Conventional piezo-driven resonant fiber optic scanners typically use quadrature piezoelectric tubes (piezo tubes) operating in 31-mode with high drive voltage and low excitation efficiency. In order to solve the abovementioned problem, a resonant fiber scanner driven by co-fired multilayer piezoelectric ceramics (CMPCs) is proposed in which four CMPCs drive a cantilevered fiber optic in the first-order bending mode to achieve efficient and fast space-filling scanning. In this paper, the cantilever beam vibration model with base displacement excitation was derived to provide a theoretical basis for the design of the fiber optic scanner. The finite element method was used to guide the dynamic design of the scanner. Finally, the dynamics characteristics and scanning trajectory of the prepared scanner prototype were tested and compared with the theoretical and simulation calculation results. Experimental results showed that the scanner can achieve three types of space-filling scanning: spiral, Lissajous, and propeller. Compared with the structure using piezo tubes, the designed scanner achieved the same scanning range with smaller axial dimensions, lower drive voltage, and higher efficiency. The scanner can achieve a free end displacement of 10 mm in both horizontal and vertical directions under a sinusoidal excitation signal of 50 Vp-p and 200 Hz. The theoretical, simulation and experimental results validate the feasibility of the proposed scanner structure and provide new ideas for the design of resonant fiber optic scanners.

“…Piezoelectric bimorph drive is a popular driving mode due to its simple structure, weak electromagnetic radiation, and absence of friction loss. The characteristics of this drive mode have made it suitable for various applications, such as optical coherence tomography (OCT) imaging, microdisplay technology, and two-photon fluorescence microscopy imaging [12][13][14][15]. For instance, Ceponis et al [16] developed an equilateral triangle structure motion platform, which utilized a piezoelectric bimorph to achieve infinite plane motion.…”

Ultrasound imaging commonly uses mechanical or electronic scanning methods. However, the mechanical scanning systems are bulky and susceptible to Electromagnetic Interference, while electronic scanning systems are complex and expensive. A more affordable and compact solution for high frequency preclinical and clinical imaging is single-element transducer based ultrasound imaging. This method offers high spatial resolution with low cost and low complexity. In this study, a novel single-element high frequency ultrasound imaging scanner was introduced. The scanner is based on piezoelectric bimorph drive and designed to be low-cost, compact, and handheld. Tungsten wire phantom imaging was performed on a dedicated ultrasound imaging system, and the obtained results were analyzed and compared. The results demonstrate that piezoelectric bimorph drive allows for high frequency imaging with a scanning speed of up to 208 frames per second. The image quality was higher than that of electromagnetic motor drive. The versatility of the ultrasound imaging system makes it suitable for preclinical and clinical applications, including small animal imaging, ophthalmic imaging, skin imaging, and intraoperative ultrasound imaging.
