  • Publication number: 20220291171
    Abstract: The present invention discloses an integrated thermocouple waveguide sensor system comprise one or more of compatible wave propagation mediums joined at one junction with at least one ultrasonic energy transducer on at least one open end of one or more wave guides and a method using the integrated thermocouple waveguide sensor system with arrangement of at least one waveguide thermocouple for integrated measurement of multiple and simultaneous physical properties of the waveguide material itself and that of the surrounding media using the Seebeck phenomena and the ultrasonic guided wave phenomena. The surrounding media properties and waveguide material properties are measured based on the ultrasonic waveguide parameters and the temperature is measured by the thermocouple.

  • Patent number: 11022502
    Abstract: This invention relates to a waveguide with distributed sensors that support traveling ultrasonic wave modes to provide quantitative local distributed sensing of the physical and chemical properties of the medium surrounding the sensor locations and/or the material properties of the waveguide. The plurality of sensors is operably associated with a plurality of wave modes for probing and identifying a plurality of properties simultaneously. The reflected waves are representative of local information about the surrounding media at that sensor location.
    Type: Grant
