Origami engineering has experienced an impressive upswing in recent years. This ancient Far Eastern folding technique has not only produced artistic creations, but has also laid the foundations for numerous technical innovations in various industries. From aerospace and the construction industry to medicine and robotics - the applications of origami folding technology are diverse and revolutionary.
What are the advantages of Origami technology?
Origami Engineering is used wherever structures need to be reduced and subsequently enlarged for spatial or functional reasons. For example, an airbag, a convertible roof or a space probe must be folded to save space before they can be used.
The pioneer of origami engineering, Robert Lang, used the principles of origami in the development of airbags ten years ago. He developed an algorithm for the optimal folding lines of the airbag. This process required fewer airbag crash tests, saving manufacturers a lot of time and money.
The same principle is applied to medical devices and implants that can be folded to a minimum size and then unfolded to the correct size. The reverse is also conceivable, for example with toothpaste tubes, which can be expressed completely.

Often it is also a matter of providing more stability through appropriate folding techniques. Flat materials into which wrinkles are inserted are more resilient and also have shock-absorbing properties. The compressive strength and rigidity of objects is also increased. Solutions for stable packaging that are produced from a single piece without cuts can be a field of application in this respect.
In addition, Origami can save material costs and time. This allows even complex components to be manufactured from a single piece without bonding, riveting or welding, reduces storage and transport costs through volume savings and reduces the number of work steps required in production and application.
"Technical origami is unique, efficient and offers a wider range of applications than conventional manufacturing processes. Kristina Wißling, Managing Director of "Origami for Industry"
Origami in the packaging
The unusual packaging design of the Nike Sport Ball even earned Nike the DuPont Diamond Awards finalist status. The creative combination of geodesic design and origami elements is characterized above all by the low material consumption and high visibility of the product. In addition, the packaging has a favourable CO2 balance. Overall, the packaging thus creates a high appeal for the product and strengthens the brand.

Miura folding for curved surfaces
The materials researchers at Harvard University in Cambridge have ambitious goals. They want to use origami technology to create any shape with a suitable fold, build houses and develop nanostructures. In a study, the researchers have now been able to prove that curved surfaces can also be folded together easily with the so-called Miura folding.
The decisive advantage of the Miura folding is its unusually high flexibility. This folding technique can also be used to refold curved surfaces, such as a curved vase, a sphere or a hyperbolic paraboloid. The developed software calculates e.g. from the vase the necessary position of the folding edges and delivers the data to a production machine. Possible applications include space travel, the packaging industry and minimally invasive surgery.
Origami "Zippered Tube" for thick materials
One of the biggest challenges in origami engineering is folding thick materials. They can usually only be bent if they are cut through and hinged. With this technique, folding only works in one direction. But researchers have now developed the origami "Zippered Tube", which solves this problem and opens up new structural options. The folding technique and some prototypes are explained here:
DNA Origami - Transport Robots from DNA
The basic principles of origami have also found their way into nanotechnology and biomedicine, albeit still predominantly into basic research. DNA origami is the term used to describe methods for folding DNA in order to create any two- and three-dimensional shapes on the nanoscale. In this respect, nanoresearchers in DNA orgami use DNA as a building material for nanometer-scale objects.
The different methods and the almost limitless possibilities for forms and structures of DNA open up a wide range of applications in medicine, biochemistry, physics and materials science. In the future, the midgets are to be equipped with useful functions:
- DNA forms could include medical active substances and release them specifically in the body or cells (e.g. active substances are released in the presence of certain DNA sequences or other signalling molecules).
- In the future, certain DNA forms could be used to capture molecules or even entire viruses in an organism and keep them under lock and key.
- Theoretically, sensors can also be developed from the forms that can be produced with high precision.
- DNA moulds can serve as frameworks or moulds that can be used to impress a desired shape on other materials.
- Furthermore, origami structures could serve as a framework for conductive materials on microchips or semiconductors, making them even smaller.
- Applications are also conceivable as a framework for carbon fibers, which could be brought into certain shapes with extreme precision.
In the future, these artificial nanobots or nanomachines may even exhibit a similar degree of effectiveness and complexity as the natural nanomachines in our cells. We can look forward to future developments.
Conclusion: The future of origami engineering
Origami Engineering is a relatively new field whose innovative potential is increasingly recognized by manufacturers and engineers. The technology can be applied to many other applications and industries. Therefore, a rapid further development of origami engineering is to be expected in the coming years - in the fields of surface technology, medicine, robotics as well as in the design of innovative, foldable structures and materials. Many a research and development task becomes much easier if you use origami techniques as an analogy for future-oriented innovations in your own field.
