“…In addition, according to the direction of vibration, the piezoelectric actuator can be divided into a longitudinal structure [128], a longitudinal bending structure [129], a longitudinal torsion [130], and a curved bending structure [128]. The length affects the modal frequency of the longitudinal structure, and length and cross-sectional dimensions structure affect the modal frequency of the bending and torsional structure [131].…”

The booming wearable market and recent advances in material science has led to the rapid development of the various wearable sensors, actuators, and devices that can be worn, embedded in fabric, accessorized, or tattooed directly onto the skin. Wearable actuators, a subcategory of wearable technology, have attracted enormous interest from researchers in various disciplines and many wearable actuators and devices have been developed in the past few decades to assist and improve people’s everyday lives. In this paper, we review the actuation mechanisms, structures, applications, and limitations of recently developed wearable actuators including pneumatic and hydraulic actuators, shape memory alloys and polymers, thermal and hygroscopic materials, dielectric elastomers, ionic and conducting polymers, piezoelectric actuators, electromagnetic actuators, liquid crystal elastomers, etc. Examples of recent applications such as wearable soft robots, haptic devices, and personal thermal regulation textiles are highlighted. Finally, we point out the current bottleneck and suggest the prospective future research directions for wearable actuators.

“…Some authors report on USMs used in extreme environments such as: the minor planet and deep sea exploration [22], [23]. In general, TWUM is the most widely known representative of ultrasonic motors [24], [25]. The principle of operation is based on the making of a travelling wave on the surface of the stator.…”

The development process and experimental investigation of the multicell piezoelectric motor is presented in this paper. The proposed design consists of three individual cells integrated into the stator, double rotor, and a preload system. Those elements are combined into a symmetrical structure of the motor. The two new prototypes have been designed, simulated and tested. Finite element numerical analysis is carried out to obtain optimal dimensions of the individual cell in terms of generated vibrations and resonant frequencies of the structure. The results of the numerical analysis are compared with analytical calculations based on the equivalent circuit model. The stator of the motor was manufactured using a three-dimensional (3-D) printer using alumide material. Finally, the experimental tests were conducted and presented. Analytical, numerical and experimental results are in satisfactory agreement. Two new prototypes of the multicell piezoelectric motor exhibit torque-speed characteristics similar to the original while being cheaper and easier to manufacture.INDEX TERMS piezoelectric actuator, piezoelectric ultrasonic motor, piezoelectricity, travelling wave motor, rotary motor.
