Many technologies, established or emerging, rely on soft and highly deformable structures, more particularly thin sheets, barriers or interfaces, with adaptable and programmable shape. These include deployable structures used in medicine (stents) or space (antennas, solar arrays or sails, etc), which possess ultra-low weight, compact stowage, and which can be remotely assembled into a precise shape. As a matter of fact, the design of devices and structures with adaptable shape is greatly simplified if the shape-morphing principle is embodied in the material that defines the thin sheet.
