Refractory Plasmonic Sensors for Harsh Environments

Background

Process control systems, such as those used in industrial and chemical processing and manufacturing, rely on ambient conditions sensors to provide real time measurement of various physical parameters such as temperature, pressure, surface chemistry, elastic strain, or other mechanical load. These sensors are often deployed in high temperature, chemically aggressive, or mechanically harsh environments, which causes the failure of the electronic devices required for said measurements. Temperatures exceeding a few hundred degrees Celsius may lead to electronic component failure and require the use of a complex cooling system, adding to the complexity and cost of the system.

Technology Summary

Researchers at Purdue University have developed an optical sensor system that can withstand temperatures up to 2500 degrees Celsius in chemically aggressive and harsh environments that impose stress, strain, and vibrations. The system uses refractory plasmonic metamaterials/metasurfaces deposited onto the surface of the harsh-environment device to monitor variations in the parameters being measured. This optical sensor system enables remote sensing, which allows for the location of detection sensors and ancillary electronics outside of the harsh environment. This technology provides real time information on harsh environmental parameters such as temperature, strain, corrosion, creep, or fatigue.

Advantages

  • Withstand temperatures up to 2500 degrees Celsius
  • Withstand chemically aggressive and harsh environments that impose stress, strain, and vibrations
