Abstract

Owing to their small size, microrobots have many potential applications. In addition, four-dimensional (4D) printing facilitates reversible shape transformation over time or upon the application of stimuli. By combining the concept of microrobots and 4D printing, it may be possible to realize more sophisticated next-generation microrobot designs that can be actuated by applying various stimuli, and also demonstrates profound implications for various applications, including drug delivery, cells delivery, soft robotics, object release and others. Herein, recent advances in 4D-printed microrobots are reviewed, including strategies for facilitating shape transformations, diverse types of external stimuli, and medical and nonmedical applications of microrobots. Finally, to conclude the paper, the challenges and the prospects of 4D-printed microrobots are highlighted.

摘要

由于尺寸微小，微型机器人有许多潜在应用。此外，四维（4D）打印有助于随时间或在施加刺激时实现可逆的形状转变。通过结合微型机器人和4D打印的概念，有可能实现更复杂的下一代微型机器人设计，这些设计可以通过施加各种刺激来驱动，并且对包括药物递送、细胞递送、软机器人技术、物体释放等在内的各种应用也具有深远意义。在此，综述了4D打印微型机器人的最新进展，包括促进形状转变的策略、各种类型的外部刺激以及微型机器人的医学和非医学应用。最后，为总结本文，强调了4D打印微型机器人面临的挑战和前景。
