材料ではなく形状によって機能が変化する構造を機械的メタマテリアルといいます。機械的メタマテリアルは自然界では珍しい機能をいともたやすく実現し、我々の周囲のありとあらゆる構造を一新する可能性を秘めています。このプロジェクトでは、MetaCylinderという円筒型の機械的メタマテリアルの設計を通じて、力学現象の発見や伝統文化の発展を探求しています。

MetaCylinderは対称性を持つ幾何的なパターンを数学的に処理することで生成されます。なかでも螺旋状のMetaCylinderは、伸び縮みしながらねじれる螺旋的な力学特性を持つ機械的メタマテリアルとなります。哲学者ゲーテが「自然には螺旋的な傾向がある」と述べたように、つるを巻きながら成長する植物や動物の角、台風や渦潮など至る所に螺旋は存在します。螺旋状のMetaCylinderは自然の再構築という観点に於いて、茶室の概念とも通じており、茶の湯文化の一要素としての応用が期待されます。

Mechanical metamaterials are structures that change their function based on their shape, not their material. These structures have the potential to achieve rare functions found in nature and revolutionize the structures around us. Through the design of a cylindrical mechanical metamaterial called MetaCylinder, this project aims to explore the discovery of mechanical phenomena and the advancement of traditional culture.

MetaCylinder is generated by mathematically processing geometric patterns with symmetry. One example is the spiral MetaCylinder, which is a mechanical metamaterial with exotic mechanical properties that combined with stretch/compression and twist. Spirals exist everywhere in nature, from the horns of animals and growing plants that coil as they grow, to typhoons and whirlpools, as philosopher Goethe stated that “there is a spiral tendency in nature. Thus, the spiral MetaCylinder has the potential of reconstructing nature, and I plan to further explore the potential of this structure as one element of the tea ceremony culture.
