Outline of Final Research Achievements

In 3D microfabrication, advances in micro-optical fabrication methods have made it possible to construct highly precise modeling objects. However, this method requires high-power energy and large equipment, making it unproductive.
In this study, inspired by the capillary origami phenomenon where surface tension of a droplet on an elastic membrane can induce spontaneous folding of the membrane into 3D structures along with droplet evaporation, a facile strategy is established for the fabrication of complex 3D hydrogel constructs using wrinkled PDMS film. This wrinkling pattern were prepared by original out-of-plane stretching method.

Academic Significance and Societal Importance of the Research Achievements

本研究は、様々な植物が環境状況に応じて鋭敏に形態変化すること、すなわち水分が関与する湿潤応答・毛管力駆動性から着想し『液滴が着弾する基板側からのアプローチで、インクジェット技術と光造形技術を結びつける』という独自の発想で取り組んだ。微細構造を有する立体造形の応用先として期待される工学・エレクトロニクス分野の新たなコンセプト・基盤技術として、学術・産業双方への社会的波及効果は大きなものになると考える。
