Embedded Gas and Temperature Sensors for Extreme Environments

Research is active on optical sensors integrated with advanced sensing materials for high temperature embedded gas sensing applications. A portfolio of patented and patent pending technologies are available for licensing and/or further collaborative research from the U.S. Department of Energy’s National Energy Technology Laboratory (NETL). Organizations or individuals with capabilities in optical sensor packaging for harsh environment and high temperature applications are encouraged to contact NETL to explore potential collaborative opportunities.
Abstract: 
Innovative process control systems for improved efficiency and lower emissions in current and future fossil fuel-based power systems and related applications requires the development of 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 are capable of operating at temperatures approaching 1,000°C. NETL has developed a portfolio of advanced optical sensor materials that address process monitoring in harsh environments and at temperatures approaching 1,000°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.
