Many living organisms have the superb structure-editing capacity for better adaptation in dynamic environments over the course of their life cycle. However, it's still challenging to replicate such natural structure-editing capacity into artificial hydrogel actuating systems for enhancing environment-interactive functions. Herein, we learn from the metamorphosis development of glowing octopus to construct proof-of-concept fluorescent hydrogel actuators with life-like structure-editing capacity by developing a universal stepwise inside-out growth strategy. These actuators could perform origami-like 3D shape deformation and also enable the postnatal growth of new structures to adapt additional actuating states for different visual information delivery by using different environment keys (e.g., temperature, pH). This study opens previously unidentified-avenues of bio-inspired hydrogel actuators/robotics and extends the potential uses for environment-interactive information encryption.
许多生物在其生命周期中具有出色的结构编辑能力，以更好地适应动态环境。然而，要将这种自然的结构编辑能力复制到人工水凝胶致动系统中以增强与环境的相互作用功能仍然具有挑战性。在这里，我们从发光章鱼的变态发育中汲取灵感，通过开发通用的逐步内外生长策略，构建具有类生命结构编辑能力的概念验证荧光水凝胶致动器。这些致动器可以进行折纸式的 3D 形状变形，并且还可以通过使用不同的环境键（例如温度，pH 值）来促进新结构的后天生长，以适应不同视觉信息传递的附加致动状态。这项研究为仿生水凝胶致动器/机器人开辟了以前未知的途径，并扩展了环境交互信息加密的潜在用途。
