“…It should be noted that the multiple working principles are conducted by the same piezoelectric actuating elements, rather than adding other piezoelectric actuating elements. [ 211 , 212 ] On the one hand, the motion agility can be improved without increasing extra structures by integrating different resonant operating principles. As illustrated in Figure 10b , Bansevicius et al [ 213 ] proposed a resonant type MPR with a hemispherical shell structure, whose standing‐wave and traveling‐wave vibrations were excited to achieve the linear and the rotational motions, respectively, the motion agility was successfully improved.…”

Miniature robots have been widely studied and applied in the fields of search and rescue, reconnaissance, micromanipulation, and even the interior of the human body benefiting from their highlight features of small size, light weight, and agile movement. With the development of new smart materials, many functional actuating elements have been proposed to construct miniature robots. Compared with other actuating elements, piezoelectric actuating elements have the advantages of compact structure, high power density, fast response, high resolution, and no electromagnetic interference, which make them greatly suitable for actuating miniature robots, and capture the attentions and favor of numerous scholars. In this paper, a comprehensive review of recent developments in miniature piezoelectric robots (MPRs) is provided. The MPRs are classified and summarized in detail from three aspects of operating environment, structure of piezoelectric actuating element, and working principle. In addition, new manufacturing methods and piezoelectric materials in MPRs, as well as the application situations, are sorted out and outlined. Finally, the challenges and future trends of MPRs are evaluated and discussed. It is hoped that this review will be of great assistance for determining appropriate designs and guiding future developments of MPRs, and provide a destination board to the researchers interested in MPRs.

“…Certain researchers, such as Zhang et al and Liu et al, have utilized commercial FEA software to investigate the steady-state vibration characteristics of piezoelectric actuators, including modal resonant frequency and amplitude responses. [41,42] However, these studies lack a comprehensive examination of the vibration characteristics of undulation robots in the time domain. Recently, Gohari et al applied piezoelectric linear theory and classical plate theory to develop an analytical solution for the bending response of smart piezoelectric laminates with flexible spring boundary structures.…”

Numerous proposals and recommendations have been made in the development of underwater undulation robots, but very few studies have focused on the undulation characteristics of undulation robots. The undulating mode of the clearnose skate utilizing the activation of the pectoral fins in undulatory bursts is particularly suitable for slow and efficient swimming. Inspired by the working principle of the clearnose skate, herein, an undulation robotic structure is presented. Considering the hydrodynamic skeleton and propulsion mechanism of the clearnose skate, the solution is based on a piezoelectric composite for realizing undulatory propulsion. This approach leverages the converse piezoelectric effect and modal coupling to produce the desired undulating motion, thereby achieving the undulation design of the robot. The proposed robotic structure can realize the propulsion mode using piezoelectric composites to undulate in the same direction and can use the clockwise or counterclockwise undulation of piezoelectric composites to achieve the steering mode. In addition, finite element analysis is employed as an approach to investigate the undulation characteristics and transient vibration characteristics of the robot. The operational efficiency of the robotic structure is assessed through experiments. The results show that the propulsion mode achieves the speed of 3.33 body‐length s−1. The steering mode exhibits the steering velocities of 17.4 deg s−1.

“…Nowadays, the most representative piezoelectric motors include single mode motor which exploits two bending modes with the same order number [4][5][6], and composite mode motor which utilizes two different types of vibrational modes, such as longitudinal-bending [6][7][8], longitudinal-torsional [9,10], and bending-torsional modes [11,12]. However, the working modes of existing piezoelectric motors are typically fixed and should be simultaneously excited [13][14][15][16][17][18][19][20]. Furthermore, the chosen vibrational modes can normally be electrically excited by only one method [21][22][23][24][25][26][27][28][29][30].…”

This paper explores interactions between multiple operating modes of piezoelectric motors. The developed motor can operate in the second-order in-plane bending modes (I), the third-order in-plane bending modes (II) and the first-order out-of-plane bending modes (III). These working modes excited separately and simultaneously, can be manipulated electronically. Each of the vibrational modes can both be driven by applying single-phase and two-phase voltages to piezoelectric ceramic plates. In order to produce all the vibration states, the structural parameters of stator were strictly designed to harmonize two eigenfrequencies of each type of vibrational modes by using finite element software ANSYS. Displacement characteristics of stator driving particles under all vibration states were calculated to evaluate mutual effects of different operating modes. Simulation results reveal that the superposition of I and II corresponds to a mode with lower resonance frequency and larger vibration amplitude in stator body. For the designed motor, the conjunction of modes I and II actually forms the first-order in-plane vibrational mode B01. Therefore, the response displacement of stator driving points reaches the maximum value when modes I and II are conjointly actuated by supplying single-phase excitation voltage under the premise of undistorted three-dimensional motion trajectory. The motor performances under that condition were also investigated experimentally. The dimension of the fabricated prototype motor is 10 mm × 10 mm × 20 mm. The stall torque is 0.2 N·m under 200 V single-phase excitation, when the motor operates in modes I and II simultaneously. The maximum no-load speed is 74 r min−1. Compared with separate actuation of vibrational modes I and II, mechanical properties of the prototype motor are significantly improved.
