Innovative process control systems for improved efficiency and lower emissions in current and future fossil-fuel-based power systems and related applications require durable, embedded sensor technology that can operate at higher temperatures and in harsh conditions.

Currently available sensor technologies have limitations including functional temperature ranges, durability, and cost. There is a clear need for remote gas sensors that operate at temperatures approaching 1000 °C.

A portfolio of advanced optical sensor materials was developed that addresses process monitoring in harsh environments and at temperatures approaching 1000 °C. These inventions integrate metal oxide-based functional sensor layers with optical waveguide-based platforms for gas composition analysis and other process variables. The novel materials and simplified fabrication processes are anticipated to provide for embedded sensors demonstrating long-term durability and functionality. The materials provide sensing responses across a broad range of wavelengths that potentially can be used to construct multisensory arrays with enhanced sensing capabilities.
