Nature uses controlled folding and unfolding mechanisms to produce versatile architectures ranging from proteins to plants. This talent triggered the interest of scientists in so-called "origami assembly methods". Origami, the traditional Japanese paper art, is a folding technique to form elegant and complex three-dimensional objects from planar sheets of paper. In wet-folding origami, a modified approach, the paper is wetted to enhance its pliability, while still retaining sufficient handling strength.
