There is growing demand for multiresponsive soft actuators for the realization of natural, safe, and complex motions in robotic interactions. In particular, soft actuators simultaneously stimulated by electrical and magnetic fields are always under development owing to their simple controllability and reliability during operation. Herein, magnetically and electrically driven dual-responsive soft actuators (MESAs) derived from novel nickel-based metal-organic frameworks (Ni-MOFs-700C), are reported. Nanoscale Ni-MOFs-700C has excellent electrochemical and magnetic properties that allow it to be used as a multifunctional material under both magnetoactive and electro-ionic actuations. The dual-responsive MESA exhibits a bending displacement of 30 mm and an ultrafast rising time of 1.5 s under a very low input voltage of 1 V and also exerts a bending deflection of 12.5 mm at 50 mT under a high excitation frequency of 5 Hz. By utilizing a dual-responsive MESA, the hovering motion of a hummingbird robot is demonstrated under magnetic and electrical stimuli.
为了在机器人交互中实现自然、安全和复杂的运动，对多响应软驱动器的需求日益增长。特别是，由电场和磁场同时刺激的软驱动器由于其在运行过程中简单的可控性和可靠性而一直在开发中。在此，报道了源自新型镍基金属有机框架（Ni-MOFs-700C）的磁电驱动双响应软驱动器（MESA）。纳米级Ni-MOFs-700C具有优异的电化学和磁性能，使其能够在磁活性和电离子驱动下用作多功能材料。双响应MESA在1V的非常低输入电压下表现出30mm的弯曲位移和1.5s的超快上升时间，并且在5Hz的高激励频率下在50mT下也施加12.5mm的弯曲挠度。通过使用双响应MESA，展示了蜂鸟机器人在磁和电刺激下的悬停运动。
