Smart materials have an important role in modern applications. They have contributed to improving various applications in several fields. One of the areas most affected by the improvement of smart materials is nanostructures. These materials are created by basic techniques, such as arrangement manipulation. Significant efforts have been made to enhance smart materials so that they resemble natural materials in terms of accuracy, design, and utility. Here, a review of the latest research on smart materials that can alter the electrical properties of nanostructures is presented. The main objective of this review is to introduce the role of smart materials in controlling the electrical performance of nanostructures. Furthermore, this review proposes an analysis of the integration and cooperation of previous research, such as the use of a piezoelectric motor in the design of structural magnetic nanodevices to control these devices. Piezoelectric actuators can also be used to develop a new method for controlling PV modulators for fabricating a single-wall nanotube. This new proposal could alter the properties of many nanoscale systems serving several medical and engineering fields. Moreover, this review proposes a novel methodology for nanocoating by introducing an antireflective coating with multiple layers. This method can effectively enhance the functions of the nanoscale coating.

“…Here, since we aimed to prove the potential of using torsional and flexural vibrations to achieve high performance, we adopted a simple structure to achieve modal degeneration; this caused fr to be in the audible range. In the future, we will shorten the vibrator to change fr into the inaudible range [18,[26][27][28][29][30]. Table 2 lists the results.…”

A piezoelectric motor driven by the first-order torsional and first-order flexural (T/F) vibrations is designed, fabricated, and tested in this study. The actuating force is generated by the torsional vibration of the dumbbell-shaped vibrator, while the elliptical motion shape is adjusted with the flexural vibration. The rotor, pressed onto the vibrator’s lateral surface, is frictionally driven with the vibrator. Here, the torsional vibration, the shear modes of piezoelectric ceramics, and the driving method may contribute to high torque and high output power. To test the feasibility of our proposal, first, a prototype of the T/F vibrator is built and its vibration properties are explored. As predicted, the torsional and flexural vibrations are excited on the vibrator. Then, the load characteristics of the piezoelectric motor are investigated. The maximal torque, the no-load rotation speed, and maximal output power are 4.3 Nm, 125 r/min, and 16.9 W, respectively. The results imply that using the first-order torsional and the first-order flexural vibrations is a feasible method to achieve high torque and high output power of piezoelectric motors.

This paper aims to develop a simple piezoelectric beam conveyor based on the standing wave principle, and explore the effect of the height of the teeth on the piezoelectric beam and the number of piezoelectric plates on the motion. Based on the Euler–Bernoulli beam theory and Lagrange equation, the Chebyshev polynomial is used as the admissble displacement function to establish the numerical model. And the ANSYS is used to verify the correctness of the numerical model calculation results. The vibration response of the tooth tip is calculated by the numerical integration method, and the effect of different excitation parameters on the motion trajectory of the tooth tip is derived. Finally, an experimental device is built to verify the effectiveness and efficiency of the device to drive the slider. The bi-directional motion of the slider is realized. And the effects of voltage amplitude, frequency, tooth height, preload force, and the driving quantity of piezoelectric plates on the slider motion speed and driving force are discussed. The conclusion is informative for the selection of teeth and preload force.
