Dr. Miao Yu and Research Team Receives PatentDr. Miao Yu and her research team, Ph.D. student Hyundae Bae and post-doctorate researcher Xuming Zhang, received a patent for an “Ultra-Miniature Fiber-Optic Pressure Sensor System and Method of Fabrication” (U.S. Patent 8,151,648; April 10, 2012). Dr. Yu was the principal investigator of the project.
The sensor that Dr. Yu and her team developed uses polymer processes that provide a high level of sensitivity with a small sensor while maintaining a high level of accuracy at a more affordable cost compared to optic sensors made with silicon or glass. This sensor also uses a 45 degree angle surface at the end of the optical fiber, which allows it to be directly mounted on a structure surface or embedded in a shallow channel to accurately measure static pressures even in the presence of surface flows. This system could be used in in a variety of fields that would require miniature and inexpensive sensors for reliable static and transient pressure measurements of fluids.
This is not the first patent for Dr. Yu. She also received a patent for a “Micro-Optical Sensor System for Pressure, Acceleration, and Pressure Gradient Measurements” (U.S. Patent 7,428,054; Sept. 23, 2008) and was part of the research team that invented a “Fiber Tip Based Sensor System for Measurements of Pressure Gradient, Air Particle Velocity, and Acoustic Intensity” (U.S. Patent 7,224,465; May 29, 2007).
