Electronic origami with the color-changing function

Origami is one of the traditional creative activities in Japan. In recent years, its artistic quality is highly evaluated. Some origami works use LEDs, muscle wires or other electronic components. The authors paid attention to the colors of origami and produced color-changing one. We held a workshop for the color-changing origami to get a lot of origami works from the participants. Our origami uses thermochromic ink and conductive ink and it can be folded in the same manner as paper origami since it does not contain any hard electronic components. This document describes the details of the electronic origami, its works, impression of the users and the future vision. This tool is expected to expand the potential of expression by origami.
