In recent decades, origami has been explored to aid in the design of engineering structures. These structures span multiple scales and have been demonstrated to be used towards various areas such as aerospace, metamaterial, biomedical, robotics, and architectural applications. Conventionally, origami or deployable structures have been actuated by hands, motors, or pneumatic actuators, which can result in heavy or bulky structures. On the other hand, active materials, which reconfigure in response to external stimulus, eliminate the need for external mechanical loads and bulky actuation systems. Thus, in recent years, active materials incorporated with deployable structures have shown promise for remote actuation of light weight, programmable origami. In this review, active materials such as shape memory polymers and alloys, hydrogels, liquid crystal elastomers, magnetic soft materials, and covalent adaptable network polymers, their actuation mechanisms, as well as how they have been utilized for active origami and where these structures are applicable is discussed. Additionally, the state‐of‐the‐art fabrication methods to construct active origami are highlighted. The existing structural modeling strategies for origami, the constitutive models used to describe active materials, and the largest challenges and future directions for active origami research are summarized.This article is protected by copyright.

“…Over the past decades, Origami structure, as one special type of patterned structures characterized by mountain and valley like creases, has attracted significant attention and * Authors to whom any correspondence should be addressed. offers an artistic method to design metamaterials with special characteristics, such as diverse configurations [1][2][3], predictable deformation behaviors [4][5][6], large folding ratios [7,8], controllable multiple stabilities [9][10][11], tunable Poisson's ratios and stiffness [12,13]. A large number of Origamiinspired metamaterials have been developed for usages from those of daily essentials to aerospace components, including umbrellas [14,15], solar panels [16,17], flexible electronics [18][19][20], and vibration isolation devices [21][22][23].…”

Origami structures have been widely applied for various engineering applications due to their extraordinary mechanical properties. However, the relationship between in-plane rotating coupling and energy absorption of these Origami structures is seldomly studied previously. The study proposes a design strategy that utilizes identical-twin rotation (i.e., simultaneous rotation with the same chirality) and fraternal-twin rotation (i.e., simultaneous rotation with the opposite chirality) of Kresling metamaterials to achieve multimodal rotation coupling and enhanced energy absorption. Deformation mode and energy absorption properties of 3D-printed Kresling metamaterials have been studied using both quasi-static compression tests and finite element analysis. Furthermore, effects of polygon units and their connections to 2D and 3D arrangements, which generate 4×4 arrays and 2×2×2 arrays, have been investigated to identify the optimized structures for achieving ultra-high energy absorption of chiral Kresling metamaterials. Results showed that rotating coupling of chiral identical twins in multimodal Kresling metamaterials possesses diverse deformation patterns and ultra-high energy absorption. This study provides a novel strategy to optimize structural designs and mechanical properties of the Kresling metamaterials.
