Popping materials and devices from 2D into 3D Curved, thin, flexible complex three-dimensional (3D) structures can be very hard to manufacture at small length scales. Xu et al. develop an ingenious design strategy for the microfabrication of geometric mesostructures that derive out-of-plane buckling originally planar structural layout (see Perspective by Ye Tsukruk). Finite element analysis mechanics makes it possible two patterns, which is then attached a previously strained substrate number points. Relaxing causes patterned material bend buckle, leading its shape. Science , this issue p. 154 ; see also 130
