“…(4) Sharing similar applications with the Yoshimura pattern is the diagonal pattern, which consists of adjacent parallelograms, each divided diagonally along opposite two corners. When tessellated, this pattern is commonly induced under the torsional buckling of a cylindrical structure, allowing it to deform a particular section and shorten in height [17].…”

Developments in surgery have been geared toward minimizing the invasiveness of the procedure to improve both the treatment itself and the patient's postoperative wellbeing. As such, attention has been directed toward reducing human error and miniaturizing clinical devices by developing smaller devices and robotic systems. While there have already been significant advancements in this area, apparatus can further benefit from being foldable, expandable, and further condensable. By promoting these characteristics, origami engineering, which extrapolates the fundamental principles of paper folding to real-world projects, has become increasingly prevalent in the biomedical field. This paper reviews the field of origami engineering, its fundamental mechanical and mathematical properties, and the recent progress in specific research areas. Then, this paper discusses several devices that have emerged over the past decade in detail based on their characteristics and implementations. Finally, this paper addresses the technical challenges and general research trend of self-folding non-invasive miniature robots.

“…Origami tessellations are origami-folding patterns that repeat themselves and therefore can be scaled up and down depending on application, with the potential of the fold being infinitely repeated. Different tessellations are enabled for acute management of preand post-shape recovery as well as how the polymer would origami-move between the states [41,42]. The design of the scaffolds was split into microstructure and macrostructure design.…”

Origami structures have attracted attention in biomedical applications due to their ability to develop surgical tools that can be expanded from a minimal volume to a larger and functional device. On the other hand, four-dimensional (4D) printing is an emerging technology, which involves 3D printing of smart materials that can respond to external stimuli such as heat. This short communication introduces the proof of concept of merging origami and 4D printing technologies to develop minimally invasive delivery of functional biomedical scaffolds with high shape recovery. The shape-memory effect (SME) of the PLA filament and the origami designs were also assessed in terms of deformability and recovery rate. The results showed that herringbone tessellation origami structure combined with internal natural cancellous bone core satisfies the design requirement of foldable scaffolds. The substantial and consistent SME of the 4D printed herringbone tessellation origami, which exhibited 96% recovery compared to 61% for PLA filament, was the most significant discovery of this paper. The experiments demonstrated how the use of 4D printing in situ with origami structures could achieve reliable and repeatable results, therefore conclusively proving how 4D printing of origami structures can be applied to biomedical scaffolds.

“…In order to solve the above two seemingly contradictory requirements, multifarious solutions have been proposed such as wavy structural configuration [ 14 , 15 ], island-interconnect configuration [ 16 , 17 ], fractal design of stretchable interconnects [ 18 , 19 ] and origami and kirigami structural configurations [ 20 , 21 , 22 ]. Among them, as a fresh structural design method, the origami structures can achieve more complex and novel structures that cannot be accomplished by other methods [ 23 , 24 , 25 , 26 ].…”

The importance of flexibility has been widely noticed and concerned in the design and application of space solar arrays. Inspired by origami structures, we introduce an approach to realizing stretchable and bendable solar arrays via horseshoe-shaped substrate design. The structure has the ability to combine rigid solar cells and soft substrates skillfully, which can prevent damage during deformations. The finite deformation theory is adapted to find the analytic model of the horseshoe-shaped structure via simplified beam theory. In order to solve the mechanical model, the shooting method, a numerical method to solve ordinary differential equation (ODE) is employed. Finite element analyses (FEA) are also performed to verify the developed theoretical model. The influences of the geometric parameters on deformations and forces are analyzed to achieve the optimal design of the structures. The stretching tests of horseshoe-shaped samples manufactured by three-dimensional (3D) printing are implemented, whose results shows a good agreement with those from theoretical predictions. The developed models can serve as the guidelines for the design of flexible solar arrays in spacecraft.
