A team of scientists at Johns Hopkins University in the U.S. has designed a mass-production strategy to create monolayer graphene-based reversible self-folding structures. The material may find potential uses in microfluidics and micromechanical systems.
As proof of concept, the team achieved complex and functional devices in the form of rings, polyhedra, flowers and origami birds. They then integrated gold electrodes to the constructs to improve their detection sensitivity. The experiments suggest a comprehensive framework to rationally design and fabricate scalable and complex, 3D, self-folding optical and electronic devices by folding 2D monolayer graphene.
