Abstract

See full text

A monitoring method and system include an antenna disposed spaced from a structural member (SM), which itself can be the target object or attachable to a target object, without using any in-dwelling strain sensor. The antenna is arranged to not touch the SM in at least the no load condition. As the target object undergoes displacement and/or deformation, the SM undergoes displacement and/or deformation. The SM is juxtaposed, partially contained with, or fully contained within a magnetic or electromagnetic field and electromagnetically coupled to the emitting antenna. Characteristics of the electromagnetic field coupling between the antenna and the SM shift over time due to the displacement and/or deformation applied to the SM. The shift in the characteristics of the electromagnetic field coupling between the antenna and the SM over time can be used to determine the temporal change in deformation and/or displacement of the SM over time to enable diagnosis of the target structural object being monitored.
