Designing a Passive Folding String Device with an Electromagnet

Atsushi Masumori, Masayoshi Mitsui and Hiroya Tanaka

Abstract (Excerpt)

We propose a passively foldable string device. This string device is composed of multiple modules which have an electromagnet on each face. The string is folded according to the pattern of the magnetic poles of the electromagnets, like proteins that fold according to the order of amino acids. It is unfolded if all the magnets have the same polarity. This string can be folded even if the string is long and heavy using an external force, for example a vibration or convection. This kind of device can be used not only as an experimental tool for studying a selffolding process but also as a three-dimensional physical display. In this paper, we propose a design of the folding string device and show some results of experiment for verification of this idea.
