MIT Scientists’ “4D Materials” Shape-Shift into Human Face

Nicknamed “active origami,” and referred to as a shape-morphing system, an MIT-developed “4D material” begins flat but can blossom into something more complicated when its surrounding conditions change. Specifically, its 3D-printed lattice structure, which mimics mesh, expands through temperature variation and actually turns into the face of scientist Carl Friedrich Gauss. The visual was reverse engineered and Gauss was selected as the sculptural result to honor his 1828 “Therema Egregium,” which helped many scientists believe that the universe is flat.
