Manufacture Technologies for Magnetoactive Deployable Structures

Nowadays, smart materials like magnetoactive materials are utilized to manufacture deployable structures, enabling these mechanisms to self-fold under external magnetic fields. Fabrication of magneto-sensitive deployable structures have evolved from using discrete magnets to applying 4D printing-an emerging technique. The new printing concept expands the application area of magnetoactive mechanisms because properties of them can be predetermined and precise arrangement of magnetic domains are realized. This review summarizes fabrication technologies for magnetoactive deployable structures, including 4D printing.
