Summary:Researchers at Rice University have developed a method to make atom-flat sensors, including photosensors, that seamlessly integrate with devices to report on what they perceive. Electronically active 2D materials have been the subject of much research since the introduction of graphene in 2004. Even though they are often touted for their strength, they're difficult to transfer to where they're needed without destroying them. The new research provides a way to keep the materials and their associated circuitry, including electrodes, intact as they are moved to curved or other smooth surfaces.
