Geometric Design and Manufacturing of Mechanical MetaMaterials

Through geometric design, origami and kirigami engineering, and additive manufacturing, we create scalable, mechanical metamaterials that can undergo large mechanical deformation for shape conforming, space saving, and shape transformation from 2D to 3D.  By study mechanical instability in (patterned) polymer gels (wrinkling, crumpling, and folding), we explore their biological relevance in cells and organoids, and formation of responsive, living networks.
