How can we wrap a 3d object with a sheet of paper without folds? Wrapping implies the ability to stretch as much as bend. Using concepts from fractal geometry, we have designed and realized a new class of materials with unprecedented control of stretchability and bendability to conformally wrap any shape or expand to nearly any predetermined shapes.
