Magneto‐X Effects in Magnetic Soft Materials and Their Applications

Magnetic soft materials (MSMs) represents an emerging class of composite materials that integrate magnetic responsiveness with the mechanical compliance of soft polymers, gels, and fluids. This review systematically summarizes the fundamental magneto-responsive effects-including magnetorheological, magnetoelastic, magnetothermal, magneto-driven deformation, magnetoresistive, and magnetoelectric effects-and classifies MSMs by matrix and filler type. It highlights recent multidisciplinary advancements in soft robotics, biomedical engineering, and flexible electronics, demonstrating their capabilities in untethered actuation, targeted therapy, and self-powered sensing. Finally, the review addresses persistent challenges such as multi-physics modeling and scalable fabrication, while outlining a future roadmap toward intelligent, integrated systems. This work provides a comprehensive reference for advancing the science and application of MSMs across multiple fields.
