Abstract Scope |
Real time monitoring of electrical assets for incipient failure detection and operational performance optimization presents significant challenges for electrical sensor integration. Due to the lack of electrical wires and interference, optical fiber based sensors show significant promise. However, costly optical instrumentation has been a challenge for commercialization of optical fiber based electrical asset monitoring. Plasmonic and nanocomposite material functionalized fiber optic sensors show significant promise for ultra low-cost sensing probes through simplification of the required optical instrumentation. We will emphasize on Au-nanoparticle incorporated nanocomposites displaying a localized surface plasmon resonance (LSPR) within various dielectric matrices for both temperature and chemical sensing. Experimental results will be presented for thin film nanocomposite based fiber probes, both in controlled laboratory settings and in the context of field validation. These will be complemented with optical-constant models detailing the microstructure and electronic structure of plasmonic sensing materials in the context of optical waveguide models. |
