In the past years, amount of research on active matter has grown extremely rapidly, a fact that is reflected in particular by existence more than 1000 reviews this topic. Moreover, field become very diverse, ranging from theoretical studies statistical mechanics particles to applied work medical applications microrobots and biological systems artificial swimmers. This makes it difficult get an overview over as whole. Here, we provide such form metareview article surveys existing review articles books matter. Thereby, provides useful starting point for finding literature about specific

Small‐scale actuators capable of performing multiple tasks are crucial for the advancement microfluidic technologies. These enable high‐throughput operations and support integrated solutions across a wide range applications. In this study, multipurpose magnetic microactuator (MMA) is developed with two pairs arms controlled externally through custom‐built electromagnetic system. To enhance navigational precision, circular sections named “mobility components” into MMA's design. The multitasking capability MMA demonstrated distinct applications, including particle manipulation, microassembly, micromixing, flow conveyance. to grasp total eight particles from different locations in single cycle within 46 s. During assembly process, 2D planar micro‐objects sequentially loaded, transported, assembled designated unit. For fluid control, motions observed mixing performance an efficiency 65% 20 addition, dye conveyance reach 85% distances 10 mm 30 results demonstrate capacity synergistic increased throughput, establishing it as foundation future actuators.

Piezoelectric ultrasonic motors (USMs) are actuators that use frequency piezoelectric vibration-generated waves to transform electrical energy into rotary or translating motion. USMs receive more attention because they offer distinct qualities over traditional magnet-coil-based motors, such as miniaturization, great accuracy, speed, non-magnetic nature, silent operation, straightforward construction, broad temperature operations, and adaptability. This review study focuses on the principle of their classifications, characterization, fabrication methods, applications, future challenges. Firstly, classifications USMs, especially, standing-wave, traveling-wave, hybrid-mode, multi-degree-of-freedom summarized, respective functioning principles explained. Secondly, finite element modeling analysis for design performance predictions, conventional nano/micro-fabrication various characterization methods presented. Thirdly, advantages, high small size, benefits different specific applications examined. Fourthly, advantages disadvantages highlighted. In addition, substantial contributions a variety technical fields like surgical robots industrial, aerospace, biomedical introduced. Finally, prospects challenges, well research directions in USM development, outlined, with an emphasis downsizing, increasing efficiency, new materials.
