A wireless vibratory strain sensing system, which consists of a passive wireless sensor and a dynamic wireless interrogator, is presented in this paper. The wireless sensor utilizes a microstrip patch antenna as the strain sensing element since its resonant frequency is a function of the tensile strain it experiences. A dynamic wireless interrogator that is based on the principle of frequency modulated...
We report a distributed multifunctional fiber sensing network based on weak-fiber Bragg gratings (WFBGs) and long period fiber grating (LPG) assisted OTDR system. The WFBGs are applied for temperature, strain, and vibration monitoring at key position, and the LPG is used as a linear filter in the system to convert the wavelength shift of WFBGs caused by environmental change into the power change....
