刺激响应材料是一种能够像思维一样响应外界刺激而改变自身物理或化学性质的材料，在人类智能生命系统的发展中发挥着重要作用。此外，最近开发的基于功能聚合物的软光致动器展示了它们在光刺激的控制下执行各种机械运动（诸如行走、游泳和抓握）的能力。与传统的电力驱动机器人不同，软光致动器可以同时完成光信号的感知和转换为机械功的过程，而无需复杂的串并联电路。由于它们在小型化、可控性和功能性方面的优势，它们是有希望的软机器人候选者。阐述了软光致动器在材料、结构、工作机理以及鲁棒性和智能化设计策略等方面的研究进展。此外，还强调了在执行机构中引入自反馈回路对实现自动连续运动的重要意义。如果进一步提高柔性光致动器的智能化性能，它将在仿生和医疗系统中得到应用。
Stimuli-responsive materials change their physical or chemical properties in response to external stimuli just like they have thoughts, which plays an important role in developing intelligent living systems for human beings. Thereto, recently developed soft photo-actuators based on functional polymers demonstrate their capabilities of performing diverse mechanical movements, such as walking, swimming, and gripping, under the control of the light stimulus. Different from conventional electric power-driven robots, soft photo-actuators can complete the procedures of sensing light signals and converting them into mechanical work simultaneously without complex serial-parallel circuits. They are promising candidates for soft robotics due to their advantages in miniaturization, controllability, and functionality. Herein, the progress of soft photo-actuators regarding their materials structure and working mechanisms and the design strategy for a robust and intelligent system are elucidated. In addition, the significance of introducing self-feedback loops to the actuator in realizing automatic and continuous motion is also emphasized. In future, soft photo-actuators will be utilized in biomimetic or medical systems if their intelligent performances are further improved.
