“…When the voltage ranged from 25 to 250 V, the no-load sliding speed exhibited a gradual enhancement. The output power and efficiency corresponding to 360 N were higher than those to 240 and 480 N probably because the frictional loss was smaller [40,41]. Most TW motors cannot provide high efficiencies as the vibration velocities differ among the driving feet [21,31,35].…”

In this study, we design and fabricate a tank-track-shaped stator working in two torsional modes to form a traveling-wave (TW) linear ultrasonic motor (USM). The stator comprises two torsional transducers and two kidney-shaped vibrating bodies. When voltages with a certain phase are applied to the transducers, two in-phase TWs are excited on the vibrating bodies to frictionally drive the slider. Here, the torsional vibration guarantees strong electromechanical coupling, and meanwhile, the tank-track shape ensures plural driving points and low weight; these features may facilitate realizing high thrust force density and high power density of linear motors. To examine the feasibility, first, we constructed a stator prototype 116 mm in length, 91 mm in width, and 32 mm in thickness and explored its vibration properties. The minimal standing wave (SW) ratio reaches 1.21 and the small SW components are desirable for TW motors. Then, we measured the load characteristics and found that, at the working frequency of 54.34 kHz and the phase shift of −110°, the maximal thrust force and maximal output power were 96.1 N and 27.8 W, respectively. Moreover, the thrust force density and power density reached respectively 234.1 N/kg and 67.8 W/kg, relatively high compared to the values of most conventional linear motors. This study verifies the feasibility of our proposal and paves a new way of designing powerful linear USMs. INDEX TERMS Linear ultrasonic motor, torsional vibration, traveling wave, thrust force density, power density.

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.
