“…Recently, the rapid development of shape memory polymers (SMPs) has provided a new strategy for the design of implants with minimal invasiveness. − Although the recovery stress of SMPs is lower than that of the shape memory alloy, the easily tailoring structures of SMPs and their composites incorporated with versatile functional fillers make them not only present in response to various external stimuli, e.g., heat, light, magnetic fields, and pH, but also exhibit the controllable mechanical performance from soft to stiff . This unique property opens up tremendous potential for their application in various fields, including electronic devices, aerospace, tissue engineering, , cell behavior modulation, , and information coding .…”
