Recent Advances in the Applications of Magnetic Shape Memory Polymers in Electronic Devices and Biomedical Engineering

Abstract

As electronic devices continue to evolve toward flexibility and miniaturization, and biomedical technologies advance toward precision and intelligence, the demand for smart materials has become increasingly urgent. Magnetic shape memory polymers (MSMPs), owing to their advantages of contactless magnetic actuation, multiple shape-memory effects, excellent processability, and remote controllability, have emerged as a focal research topic in both fields. This paper provides a systematic review of recent progress in the application of MSMPs in electronic devices and biomedical engineering. Emphasis is placed on material design strategies and fabrication techniques, followed by an analysis of underlying performance mechanisms and representative application cases. In-depth research on MSMPs not only helps to promote the innovative development of the next generation of intelligent devices, but also provides a brand-new technical path for disease diagnosis and treatment as well as tissue engineering repair. In addition, the major challenges currently faced by MSMPs and potential future development directions are discussed.
