Origami model for breathing alveoli

Abstract

We previously proposed a morphogenesis-based 4D model of the alveolar structure. However, the model exists only in computer, and is too complicated to be recognized in 2D display. Origami, a Japanese traditional craft, is a 4D object originated from 2D sheet. We introduce origami models approximating our computational alveolar model. One can make, see, and handle the models by oneself. Seeing is believing. We dare say "Making is convincing". © Springer Science+Business Media, LLC 2010.
