Tracing evolutions in electro-activated shape memory polymer composites with 4D printing strategies: A systematic review

Shape-memory-polymers (SMPs) have displayed many attractive features, especially in some shape memory composites that are able to respond swiftly to one or multiple particular stimuli. An intriguing application of the electrically stimulated SMPs is that they have the capability to be remotely actuated by which their primary shape is recovered. The present paper has represented a comprehensive discussion on the recent progress of...
