  • Systems and methods for wireless strain sensing
    Patent number: 11169038
    Abstract: In one embodiment, a system for determining strain within a material includes a magnetostrictive sensor configured to be embedded within the material, a sensing unit configured to apply an excitation magnetic field to the material and the embedded sensor and to receive a response magnetic field that has passed through the material and the embedded sensor, wherein the sensing unit does not contact the material, and a device configured to determine a difference between the excitation magnetic field and the response magnetic field and to determine the strain within the material based upon that difference.
    Type: Grant
    Filed: May 20, 2020
    Date of Patent: November 9, 2021
    Assignee: Board of Regents, The University of Texas
    Inventors: Wen Shen, Kenneth Reifsnider, Md Rassel Raihan, Relebohile Qhobosheane
  • Systems and methods for assessing the quality of adhesive bonds
    Patent number: 10989680
    Abstract: In one embodiment, assessing the quality of an adhesive bond of a composite material includes passing a vector electric field through a thickness of the composite material, measuring dielectric properties of the composite material, determining one or more dielectric parameters of the composite material, and comparing the one or more dielectric parameters with one or more reference dielectric parameters.
