Electric and magnetic field-driven actuation of a biomimetic soft robot using engineered Co-MOF

This study presents an innovative Cobalt-based Metal Organic Framework (Co-MOF) material with optimized magnetic properties, enabling the fabrication of a robust magnetic biomimetic soft actuator. Co-MOF based superparamagnetic material was synthesized through a serendipitous post-synthesis modification resulting in optimized magnetoactive properties. Through this route a remarkable saturated magnetization of 142.7 Am²/kg was achieved. These features allow for the creation of an eagle-like robot with a magneto-active claw that grips in response to magnetic fields. The actuator showcases potential in biomedical applications, such as drug delivery and surgical devices, due to its ability to function without tethered connections. This research opens avenues for multifunctional, kinesthetic soft robots with broad practical applications.
