Project Description

This project will demonstrate a wireless, high-temperature sensor system for monitoring the temperature and health of energy-system components. The active sensor and electronics for passive wireless communication will be composed entirely of electroceramic materials (conductive ceramics), which can withstand the harsh environments of advanced fossil-energy-based technologies.

The project will focus primarily on the fabrication and testing of temperature (thermocouples and thermistors) and health (strain/stress and crack propagation) sensors that function at extreme temperatures (500-1700 degrees Celsius). A passive wireless communications circuit will be developed to accompany the high-temperature sensor that will allow the transmission of data based on electromagnetic coupling to a nearby reader antenna, along with a “peel-and-stick”-like transfer process to deposit the entire sensor circuit on various energy-system components.

Project Benefits

The results of this research could reduce the need for interconnect wires near the active, and possibly rotating, energy-system component. It may also permit the economical and precise placement of the sensor circuit onto components of various shapes and locations, without altering the geometry and active features of the manufactured component, or the removal (or decommissioning) of the component for installation.

The developed sensor system may find application in solid oxide fuel cells, chemical reactors, furnaces, engines, boilers, and gas turbines (for both energy and aerospace applications) systems.
