Shape‐morphing structures are appealing in the material community to inspire a myriad of applications across domains, including soft robots, tissue engineering, and consumer products. However, it is a challenge to create fast response/recovery actuators with complicated and robust deformation due to the slow diffusion speed of water in hydrogel and small modulus of hydrogel. Herein, a facile strategy is proposed to fabricate a versatile patterned film configuration using chitin and poly(dimethylsiloxane) (PDMS). The direct‐ink writing (DIW) technique is leveraged to build simple, flat, patterned films, which can be morphed into complicated multidimensional architectures. Additionally, computational simulations are conducted to predict the deformation behaviors of the actuator. The sequential response structure can be precisely manipulated by the actuation speed of different structures. Moreover, an assembling method is proposed to create multifunction actuators.

具有快速和可编程多动作功能的直接墨水书面形状变形膜

形状变形结构在材料界很有吸引力，可以激发跨领域的众多应用程序，包括软机器人，组织工程和消费产品。然而，由于水在水凝胶中的缓慢扩散速度和较小的水凝胶模量，因此要创建具有复杂而坚固的变形的快速响应/恢复执​​行器是一个挑战。在此，提出了一种简便的策略来使用甲壳质和聚二甲基硅氧烷（PDMS）来制造通用的图案化膜结构。直接墨水书写（DIW）技术用于构建简单，平坦，有图案的胶片，可以将其变形为复杂的多维体系结构。另外，进行计算仿真以预测致动器的变形行为。顺序响应结构可以通过不同结构的致动速度来精确控制。此外，提出了一种制造多功能致动器的组装方法。
