“…It is connected without an intermediate speed reducer, and it also has the advantages of short focusing time, high positioning accuracy, and a simple mechanism [89]. Oohira et al, [90] applied a micro ultrasonic motor to an optical fiber crossconnect switch actuator, which successfully improved the mirror holding phenomenon and non-self-locking function of the traditional electrostatic or electromagnetic switch actuator, ensuring high-quality optical signal transmission. Yakimov [91] use an ultrasonic motor for the coarse positioning of tunnel scanning microscope table, whiles Lee et al [92] uses the ultrasonic motor for low temperature, high vacuum, and high magnetic field atomic force microscopes.…”

The advent of smart materials and modern control theory has seen the rapid development of ultrasonic motors over the last decades. They have become promising precision driving components due to their unique piezoelectric transduction and friction drive mechanisms. This review summarizes the synthesis of the key technical aspects, research efforts, conclusions, and challenges that need to be highlighted concerning ultrasonic motor structural design and tribological performance. The analysis shows that the development of ultrasonic motor with new principles is in the ascendant. Simplifying the body structure, developing advanced friction contact models and life prediction models, developing new and environmentally friendly friction materials, and developing customized tribological testing devices are goals and tasks that should be considered in the future design of efficient ultrasonic motors.

In the last decades piezoelectrically driven ultrasonic motors have become alternative actuators to the conventional electromagnetic motors especially for precise and accurate servo positioning applications. Different types of ultrasonic motors have been constructed and manufactured. Several drive systems have been designed, implemented and proposed for these motors. A variety of control techniques have been applied to them. The research given in this study covers bases of the ultrasonic motors. Theoretical background, modeling, drive systems, control techniques and applications of the ultrasonic motors have been introduced. Firstly, the general overview has been given. Then, modeling studies focused on performance estimation and analysis of ultrasonic motors have been examined. Afterwards, drive systems and control techniques of ultrasonic motors have been investigated. Furthermore, an example drive and control system has been presented. This drive system has been designed as to be controlled digitally. In addition, the important industrial and research applications of these motors have been included. The presented study has been arranged as a review of ultrasonic motors. The important points of specifications, models, drive systems and control methods of the ultrasonic motors have been emphasized.

“…Living tissue represents a natural example of DM; as to a man made implementation, this has become possible due to recent progress in technology that allows for the property tuning, specifically on a micro-and nano-scale. Some technical means towards such tuning are detailed in [3], [4], [5], [6], [7], [8]; at this point we only mention that…”

Professor Jüri Engelbrecht is widely known as an outstanding scholar in various branches of mechanics and mathematical physics. Through many years, he has been one of the main contributors to the intensive development of science and academic education in his homeland Estonia and far beyond it, on the European scale. His public service is commensurate with his scientific merits. Jüri's sphere of interests is vast, and it always belonged to the cutting edge of mechanics and thermodynamics. This is the reason why we decided to submit our work to Jüri's jubilee collection of papers; we dedicate it to our dear colleague and friend with the hope that it may get along with his long-time professional aspirations.
