Conductive leaf vein networks produced via Ag nanoparticle self-assembly for potential applications of flexible sensor

摘要

The first use of water-dispersible Ag nanoparticle (Ag NP)-based ink to produce conductive leaf vein networks in flexible bending/pressure sensors was reported. Homogeneous deposition of the Ag NPs on the leaf vein network was achieved via Ag NP self-assembly based on electrostatic interactions between poly cations and polyanions. The Ag NP covered leaf vein network was annealed at 150 degrees C to impart conductive properties with a resistance of similar to 3 to 5 Omega. The networks were utilized in potential application as flexible bending and pressure sensors. (c) 2020 Elsevier B.V. All rights reserved.
