Abstract:Magnetic materials are important stimulus-responsive materials that can be controlled wirelessly by an external magnetic field through tissues and organs. They are widely used in biomedical fields such as medical robots, artificial organs, biochemical synthesis, and drug delivery due to their high biocompatibility, simple magnetic field control, and fast regulation speed. Complex work scenarios and multifunctional requirements pose higher demands for the precise control of magnetic materials, ranging from simple planar driving based on magnetic force to complex spatial driving based on both magnetic force and torque and from functional implementation based on the material′s own motion deformation to achieving more complex environmental detection as a multifunctional flexible electronic device carrier. This article introduces the magnetic properties, magnetic field control platform, and magnetic pole programming techniques of several commonly used magnetic materials, demonstrating the application progress and numerous challenges faced by three different types of magnetic materials: Magnetic liquids, magnetic solids, and magnetic membranes, in the biomedical field. Finally, future development trends are discussed.
