Porous Magnetic Soft Grippers for Fast and Gentle Grasping of Delicate Living Objects
A porous magnetic soft gripper (PMSG) is designed to address the inherent trade?off between shape adaptability and payload capacity. The porous structure imparts low impact force and high surface friction, enabling swift yet gentle grasping. PMSGs are integrated with robotic arms and UAVs for the remote gripping and transportation of small animals.Magnetic soft grippers have attracted intensive interest due to their untethered controllability, rapid response, and biological safety. However, manipulating living objects requires a simultaneous increase in shape adaptability and gripping force, which are typically mutually exclusive. Increasing the magnetic particle content enhances the magnetic strength but also increases the elastic modulus, leading to low adaptability and high impact force. Here, a porous magnetic soft gripper (PMSG) is developed by integrating a porous structure into a magnetic silicone elastomer. The design of porous hard magnetic composite is characterized by high magnetization, low modulus, and rough surface. It offers the PMSG good compliance, high gripping force, and low impact force at fast gripping. The PMSG is capable of performing a variety of tasks, including the fast and gentle grasping of delicate living objects. The study provides insight into the design of novel magnetic grippers and may offer a promising outlook for biomedical or scientific applications in the manipulation of delicate organisms.
