软机器人由于其移动性和紧凑的尺寸，在微/纳米尺度上，特别是在生物医学工程领域，作为一种有吸引力的制造技术迅速发展。作为一种新兴的增材制造技术，四维（4D）打印可以随着时间的推移复制自然的生理机械变化，从而实现从静态到动态的转变。因此，4D打印被广泛研究和应用于从机械工程和材料科学到生物医学工程的各个领域。通过结合4D打印在某些刺激下产生动态形态变化的独特能力和基于生物相容性软材料的微/纳米机器人，一种具有精确可控性和无限可逆驱动的新平台有望增强4D打印在生物医学应用中的作用。在这篇综述中，我们系统地介绍了软机器人，并进一步总结了当前4D打印制造软机器人的方法。此外，广泛的潜在应用范围的4D软机器人在生物医学工程专门讨论。最后，我们总结了4D打印软机器人技术目前面临的挑战和限制，以及未来的发展方向。
Soft robotics has grown rapidly as an attractive manufacturing technique at micro/nanoscales, especially in the field of biomedical engineering, due to its mobility and compact size. As an emerging additive manufacturing technique, four-dimensional (4D) printing can replicate natural physio-mechanical changes over time leading the transition from static to dynamic. As such, 4D printing is widely investigated and applied in fields ranging from mechanical engineering and material science, to biomedical engineering. By combining the unique ability of 4D printing to create dynamic morphological changes under certain stimuli and biocompatible soft material based micro-/nanorobots, a new promising platform with precise controllability and unlimited reversible actuation is expected to enhance the role of 4D printing for biomedical applications. In this review, we systematically introduce soft robots and further summarize current 4D printing approaches to fabricate soft robots. Moreover, a broad scope of potential applications of 4D soft robots in biomedical engineering is exclusively discussed. We finally conclude with current challenges and limitations, as well as future directions, for 4D printing soft robot technology.
