This study starts from the counter-intuitive question of how we can render a conventional stiff, non-stretchable and even brittle material conformable so that it can fully wrap around a curved surface, such as a sphere, without failure. Here, we answer this conundrum by extending geometrical design in computational kirigami (paper cutting and folding) to paper wrapping. Our computational paper wrapping-based approach provides the more robust and reliable fabrication of conformal devices than paper folding approaches. This in turn leads to a significant increase in the applicability of computational kirigami to real-world fabrication. This new computer-aided design transforms 2D-based conventional materials, such as Si and copper, into a variety of targeted conformal structures that can fully wrap the desired 3D structure without plastic deformation or fracture. We further demonstrated that our novel approach enables a pluripotent design platform to transform conventional non-stretchable 2D-based devices, such as electroluminescent lighting and a paper battery, into wearable and conformable 3D curved devices. One Sentence Summary: Computational paper wrapping provides a novel way to wrap an arbitrary curved 3D shapes with 2D based brittle materials, such as Si and Copper. Main Text: New flexible and stretchable materials have recently attracted significant interest for fabricating conformable devices( 1-4). However, their application for real devices remains strictly limited by their failure to provide certain key criteria available in conventional devices, such as high conductivity and reliability. This study introduces a novel way to utilize conventional nonstretchable materials to reliably wrap any arbitrary 3D curved surfaces, including the human body and curved vehicle interiors as potential applications. This new approach allows us to make conformable devices without sacrificing their performance. Wrapping an arbitrary surface tightly with non-stretchable material is challenging( 5, 6). As shown in Fig. 1A, wrapping a sphere with rectangular paper cannot avoid the formation of wrinkles and overlaps. If the material is a substrate or other active layer of a flexible device, severe deformation and overlapping in the material can cause fracture or breakage of the device as shown in Fig. S1. One common way to wrap 3D surfaces with non-stretchable materials is by cutting the materials, called kirigami (paper cutting and folding) design. A recent example is kirigami-patterned cuts, such as lattice patterns and fractal cut patterns. Yigil Cho et al. proposed a mechanical meta-material by cutting planar materials with a hierarchy auxetic structure called
