These structures span multiple scales and have beendemonstrated to be used toward various areas such as aerospace,metamaterial, biomedical, robotics, and architectural applications.Conventionally, origami or deployable structures have been actuated byhands, motors, or pneumatic actuators, which can result in heavy or bulkystructures. On the other hand, active materials, which reconfigure in responseto external stimulus, eliminate the need for external mechanical loads andbulky actuation systems. Thus, in recent years, active materials incorporatedwith deployable structures have shown promise for remote actuation of lightweight, programmable origami. In this review, active materials such as shapememory polymers (SMPs) and alloys (SMAs), hydrogels, liquid crystalelastomers (LCEs), magnetic soft materials (MSMs), and covalent adaptablenetwork (CAN) polymers, their actuation mechanisms, as well as how theyhave been utilized for active origami and where these structures areapplicable is discussed. Additionally, the state-of-the-art fabrication methodsto construct active origami are highlighted. The existing structural modelingstrategies for origami, the constitutive models used to describe activematerials, and the largest challenges and future directions for active origamiresearch are summarized. 收起
