Article Synopsis
  • There is an increasing need for soft actuators in robotics that can perform complex, natural movements safely through both electrical and magnetic stimulation.
  • The study focuses on new dual-responsive soft actuators made from nickel-based metal-organic frameworks (Ni-MOFs-700C), which possess beneficial electrochemical and magnetic traits.
  • These actuators can bend significantly (30 mm) and respond quickly (1.5 s) with low energy input, enabling advanced applications like a hummingbird robot that hovers using both magnetic and electrical triggers.

In the field of bioinspired soft robotics, to accomplish sophisticated tasks in human fingers, electroactive artificial muscles are under development. However, most existing actuators show a lack of high bending displacement and irregular response characteristics under low input voltages. Here, based on metal free covalent triazine frameworks (CTFs), we report an electro-ionic soft actuator that shows high bending deformation under ultralow input voltages that can be implemented as a soft robotic touch finger on fragile displays.
