3-D 'pop-up' silicon structures: Transforming planar materials into 3-D microarchitectures

In the cover feature article of the journal, Science, researchers at the University of Illinois at Urbana-Champaign describe a unique process for geometrically transforming two dimensional (2D) micro/nanostructures into extended 3D layouts by exploiting mechanics principles similar to those found in children's 'pop-up' books.
