Polymer-Based 2D-to-3D Transformable Surfaces

Technologies using stretchable materials are increasingly important. Yet, in general, it is not possible to control how they stretch with much more sophistication than inflating balloons. A method was developed that allows the calculated transformation of 2D stretchable surfaces into targeted 3D...
