Shape Morphing Using PDE Surfaces [PDF]
, 2006 NoA methodology for shape morphing using partial differential equation (PDE) surfaces is presented in this work. The use of the PDE formulation shows how shape morphing can be based on a boundary-value approach by which intermediate shapes can be ...

Bio-inspired pneumatic shape-morphing elastomers [PDF]
Nature Materials, 2018 Shape-morphing structures are at the core of future applications in aeronautics1, minimally invasive surgery2, tissue engineering3 and smart materials4. However, current engineering technologies, based on inhomogeneous actuation across the thickness of slender structures, are intrinsically limited to one-directional bending5.

Contactless reversible 4D-printing for 3D-to-3D shape morphing
Virtual and Physical Prototyping, 2020 4D printing provides a means to create dynamic structures for self-actuating devices fabricated by additive manufacturing techniques. Most existing 4D printing processes are only capable of one-way shape morphing using a single mechanism for stimulation.
