The fabrication of thermo-magnetic dual-responsive soft robots often requires intricate designs to implement complex locomotion patterns and utilize the implemented responsive behaviors. This work demonstrates a minimally designed soft robot based on poly--isopropylacrylamide (pNIPAM) and ferromagnetic particles, showcasing excellent control over both thermo- and magnetic responses. Free radical polymerization enables the magnetic particles to be entrapped homogeneously within the polymeric network. The integration of magnetic shape programming and temperature response allows the robot to perform various tasks including shaping, locomotion, pick-and-place, and release maneuvers of objects using independent triggers. The robot can be immobilized in a gripping state through magnetic actuation, and a subsequent increase in temperature transitions the robot from a swollen to a collapsed state. The temperature switch enables the robot to maintain a secured configuration while executing other movements magnetic actuation. This approach offers a straightforward yet effective solution for achieving full control over both stimuli in dual-responsive soft robotics.
基于聚异丙基丙烯酰胺(pNIPAM)和铁磁粒子,设计了一种最小化的软机器人,其展示了对热磁双响应的出色控制。自由基聚合使磁性粒子均匀地包埋在聚合物网络中。磁形状编程和温度响应的集成使机器人能够执行各种任务,包括使用独立的触发器进行形状、运动、物体的拾取和放置以及释放操作。机器人可以通过磁致动固定在夹持状态,随后温度升高使机器人从肿胀状态转变为收缩状态。温度开关使机器人能够在执行其他运动的同时保持固定配置,通过磁致动。这种方法为实现双响应软机器人中两种刺激的完全控制提供了一种简单而有效的解决方案。
