“…The droplet ejection based on piezoelectric device, also known as PMJD and the most widely-used droplet ejected device, uses the piezoelectric ceramics as its energyconverting device due to its advantages of simple structure, high force density, high accuracy, quick responding, and good acclimatization [46][47][48][49][50][51][52][53]. The working principle of the PMJD is based on the reverse piezoelectric effect of the piezoelectric device to convert the electrical energy into mechanical energy [54], which directly works on the liquid medium near the nozzle.…”

The droplet-based 3D printing with piezoelectric micro-jet device (PMJD), also known as fabrication with droplet ejection, has shown its unique advantages exceeding typical processing in direct rapid manufacturing (DRM) of miniature and complicated metal parts, function components, and other heterogeneous devices. Recently, the droplet-based 3D printing with higher printing velocity, controllable precision and smaller printing volume is need more and more in additive manufacturing (AM) fields, which promotes the development of the droplet-based printing technology to a faster, accurate and flexible direction. In this regard, the droplet-based 3D printing with PMJD has received a lot of attentions from universities, enterprises, and other research institutes. In this review, based on introducing the droplet-based 3D printing technologies, we will clarify the advantages of droplet-based 3D printing, especially the droplet ejection with PMJD. Then, the connections and differences between the ejection of non-metallic droplets and metal droplets based on piezoelectric micro-jet are also clarified, meanwhile, the challenges, such as the consistency, reliability, and stability of piezoelectric actuated droplet ejection, are concluded and analyzed. In general, the future developments of droplet-based 3D printing technology are prospected, and the review can provide some further references for the related works.

“…Wang et al [ 261 ] developed a miniature biped piezoelectric robot with a patch‐type beam structure, which achieved linear motion with large stroke under the low frequency and voltage, and could perform transport tasks in narrow environments. And then, the team proposed a small and agile ring‐shaped tripodal piezoelectric robot, [ 262 ] which achieved the linear and rotary motions actuated by standing and traveling mechanical waves based on the propagation of mechanical waves on the rigid ring‐shaped structure. Li et al [ 41 ] proposed a miniature quadrupedal piezoelectric robot, which realized nanoresolution and high speed based on the quasi‐static and resonant motions, respectively.…”

Piezoelectric actuation technology has been widely used in various precise‐oriented fields. Its notable advantages include high resolution, rapid response speed, output force with high density, and immunity to electromagnetic interference. Characteristics of cross‐scale and multiple‐degree‐of‐freedom (multi‐DOF) output motions are of utmost importance in the context of micro‐/nanopositioning technology. For decades, researchers have been working to develop various piezoelectric devices that exploit these important properties. In this review, a comprehensive review of recent research efforts in the field of cross‐scale multi‐DOF piezoelectric drive technology is provided. To commence, it provides an in‐depth exploration of the unique advantages associated with piezoelectric actuation, demonstrating them through comparative analyses with alternative actuation methods. Subsequently, the complexity of piezoelectric cross‐scale motion is introduced, and the multi‐DOF piezoelectric motion is classified in detail. Furthermore, the practical applications of multi‐DOF cross‐scale piezoelectric actuation technology are systematically elucidated, highlighting its versatility and suitability in real‐world environments. Finally, an in‐depth discussion that addresses the challenges encountered in the field is provided, and the prospective directions for further developments in piezoelectric actuation technology are outlined. This scholarly contribution plays an important role in guiding future research and innovative initiatives.

“…In these optimization process, only individual variables are controlled separately to observe the changes of the optimization goal, which ignore the interactions between the variables [29,30]. It is inappropriate to ignore the interaction between variables and design objectives, especially when multiple optimization objectives are required [31][32][33]. Therefore, a multi-objective and multi-variable design method should be proposed to fulfill the multiple design requirements in the optimized process.…”

Piezoelectric actuators are widely utilized in the precision industry field, but the existing piezoelectric actuators are difficult to achieve high displacement smoothness at low speed, which limits the practical application of the piezoelectric actuators. This work proposes a piezoelectric actuator that can achieve high displacement smoothness through a multi-leg coordinated actuation principle. A multi-objective optimized method based on adaptive mutation genetic algorithm is utilized to design the driving leg by comprehensively considering five design variables. The design goal of the maximum displacement of the driving foot and the minimum size of the driving leg are achieved. A prototype is fabricated and the characteristics are tested. The experimental results demonstrate the effectiveness of the optimized method. High displacement smoothness at low speed is also achieved. The output displacements of the proposed actuator at different driving voltages and frequencies show no regression and intermittent motion. The linearity R 2 could reach 0.9978, and the low output speed of the actuator could reach 22.69 µrad s−1 at voltage of 100 Vp–p and frequency of 1 Hz.
