Stimuli-responsive, self-folding, two-dimensional (2-D) layered materials have interesting functions for flexible electronics, wearables, biosensors, and photonics applications. However, limits with scalability and a lack of design tools can prevent high integration and their reliable function. In a new report now published on Advanced Intelligent Systems, Qi Huang, and a team of scientists in chemical and biomolecular engineering and electrical and computer engineering at Johns Hopkins University, U.S., proposed a mass-production strategy to create monolayer graphene-based reversible self-folding structures. The material can be used in microfluidics and micromechanical systems. As proof of concept, they 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, 3-D, self-folding optical and electronic devices by folding 2-D monolayer graphene.
