Origami Research and Applications
The uses of origami are not confined to artistic expression. Insights from folding paper have been applied to space technology, automobiles, medicine and programmable matter; these applications began to appear a few decades ago. At heart is the mathematics behind the humble piece of paper, which was studied as early as the 1930s. The mathematics gives rise to challenging unsolved problems and software that design complex origami on-demand.
This article lists some of the more accessible research as it is meant as a primer to origami research, but it may be somewhat outdated.

Origami in Technology
Several technological products have been based on origami. These devices are flat and sheet-like, and they need to change their shape often, so that they can be stored and transported compactly but expand to full size for usage. The reversible folding motions of a sheet make origami the perfect answer. USA’s National Science Foundation has recognized this potential, giving USD14M of awards to projects related to “Origami Design for Integration of Self-assembling Systems for Engineering Innovation (ODISSEI).”
Solar Panels for a Satellite (1995)
In 1955, Japanese scientists used an origami technique, the Miura map fold, to fold the huge solar panels of a satellite into a small package. After the satellite entered space, the solar panels unfolded to full size and functionality.

Airbag Simulations
To ensure that the airbag of a car will inflate properly when it crashes, copies of the car will often need to be crashed in real life. However, modeling the folding surface of the airbag using origami allows engineers to replace real crash tests with computer simulations.

Origami Stent Graft (2003)

Researchers from the University of Oxford developed an origami stent graft, a tube-shaped medical device used to hold arteries open during surgery. The metal tube would be folded into a thinner shape using a special origami pattern. It would then be inserted into an artery, where body heat would cause it to unfold and expand, holding the artery open.

Other Technologies
Structural Origami
Deployable Structures: Structures that have different initial and final configurations, folding from one to the other
Deployable Structures: Structures that have different initial and final configurations, folding from one to the other
- Industrial packaging
- Self-folding microscopic origami driven by cellular traction or surface tension
- Programmable matter (structures that automatically fold to desired shapes on command)
Automated Origami Design
Programmers have written software that allow users to specify a desired origami shape and calculate its blueprint (crease pattern) based on that data. Varying programs have been written to design different types of origami, from animals to geometric shapes.
Treemaker (1998)
Robert J. Lang developed the mathematics needed to generate a pattern of lines that folds into a specified stick figure, automating the design of animal origami.

Origamizer (2008)
Tomohiro Tachi wrote this computer program to generate a blueprint that folds into a desired 3D shape with flat sides.

Other Automated Origami Design Algorithms
- Axial symmetric polyhedra by myself
- "Maze Folder" by Erik D. Demaine, Martin L. Demaine and Jason Ku that designs orthogonal mazes.
- Polycubes (3D solids composed of cubes glued together at their faces) by Aviv Ovadya
- "ORI-REF" by Jun Mitani that designs curved origami
- "ORI-REVO" by Jun Mitani that folds rotationally symmetric polyhedra
Origami Mathematics
Creases on paper form lines. Different creases meet in point and form angles. Naturally, origami is deeply tied to geometry. Seeing an origami model as a mathematical object obeying certain mathematical “laws of folding” is at the heart of every computer program used in Automated Origami Design. Problems in mathematics itself have even been solved using origami techniques.
Flat-foldable Origami

Much of origami is folded into a flat product before it is shaped into a more lifelike 3D form. Observations regarding the blueprints of flat origami formed the early “laws of folding”. One such “law” is that the regions that the blueprint divides the paper into can be colored in two colors so that no neighboring regions have the same color.

Fold-and-Cut Problem

A magic trick involved cutting out paper shapes such as stars by folding a piece of paper and making one straight cut. The mathematical problem of what shapes could be produced in this manner was solved by Demaine et al, who showed that any shape with straight sides was possible.

Other Mathematics in Origami
Beyond geometry, origami also has connections to matrices & linear algebra, abstract algebra, combinatorics, topology, differential equations and many other fields. Computational origami, the study of origami algorithms, is also an active area of research.
OSME Conferences

Many of the above pieces of research were presented at the International Conference on Origami in Science, Mathematics and Education (OSME), which inspired researchers and provided a platform for them to discuss and learn of the newest developments.
In 1989, origami researchers gathered in Ferrara, Italy for the First International Meeting of Origami Science and Technology (1OSME), where they discussed their research findings and explored new directions. This has since evolved into a highly successful series of OSME conferences. They link separate research groups from around the world, forming an international community for origami research.
Educational uses of origami have been a focus since 3OSME, the third conference in 2001. This acknowledges the possibilities of origami in demonstrating abstract geometric concepts through fun and engaging hands-on activities.
