Enhanced Flexible Electrodes based on Titanium Nitride Nanocomposites | Loik GENCE

Summary :
⁣Flexible, biocompatible electrodes are essential for the development of future wearable and implantable medical devices. While silver nanowire (AgNW) networks are promising candidates for transparent conductive electrodes (TCEs), they suffer from issues such as high roughness, low adhesion, and atmospheric corrosion sensitivity. Many flexible electrodes are made of a wrinkled conductive layer on top of a compliant substrates. Wrinkles provide a way to maintain the integrity and conductivity of the electrode while it is being stretched or bent. In this study, we report on the characterization of semi-transparent electrodes on cellulose nanopaper (CNP) substrates using a plasmaenhanced pulsed laser deposition (PE-PLD) technique. We combined AgNW with titanium nitride (TiN) layers to form wrinkled conducting nano-composite coatings with excellent electromechanical properties. Our results show that the incorporation of AgNW into TiN coatings improves the electrode’s electro-mechanical robustness. Additionally, our data show that CNP/TiNAgNW electrodes exhibit improved stability in air compared to bare AgNW coatings with improved adhesion. These findings have important implications for the development of bio-compatible flexible electronics and could pave the way for the creation of new wearable and implantable medical devices.
