# Origami and STEM by @HowToStem

There’s something about origami that really seems to capture children’s imagination. In most of the classes that I have taught over the years, there has been at least one child with a real passion for origami. Many a show-and-tell has been dominated by incredible paper-folding creations, from water bombs to paper dragons. Think back to your own school days; which of these origami classics do you remember creating?

Origami is the ancient art of Japanese paper folding and for many, a love of origami stems from childhood. As much as we might marvel at this paper art-form, do we see its potential beyond an interesting pastime? Origami has evolved to be much more than paper folding. Here are some examples, with real-world applications within areas such as engineering, medicine and technology.

Origami and maths

At a primary school level, origami is a fantastic way to explore mathematical concepts including geometry, fractions and angles. Turning a simple square of paper into a piece of completed origami involves a lot of mathematical thinking. Origami instructions involve following steps of folds, often referred to as ‘crease patterns’, in order to create different geometric constructions. Children will need to use knowledge of directionality and angles in order to complete these correctly. Throughout the process, they will create other shapes starting from a square including equilateral triangles, pentagons and hexagons. Patterns also feature heavily in origami.

The TED talk above, entitled ‘The math and magic of origami‘ explains in more detail about the complex mathematics involved in origami.

Origami and engineering

Many of the real-world applications for origami can be found within engineering. Take the example of car airbags. Did you know that their compact, quick inflating design was inspired by origami? Engineers took inspiration from origami patterns and folding methods to deploy how the airbag is stored and deployed. Engineers are continuing to draw upon origami techniques when developing new structures and technologies.

Origami and medicine

In 2003, a new, origami-inspired heart stent design was created. Designed around an origami waterbomb base, the purpose of the stent was to enlarge clogged arteries and veins. The origami design allows the stent to be expanded to different sizes depending on its application. Likewise, origami-inspired forceps are helping to revolutionise robotic surgery, allowing for delicate, precise cuts.

Origami and space

There are plenty of examples of origami-inspired space technology. One such is the solar array. The combination of different folds expands into a large, flat circular surface. These solar arrays can then be used to convert solar energy into electrical power. More examples of how NASA engineers use origami to design future spacecraft can be found here:
