“…The bandwidth variation of the reflected peak due to the transverse deformation is obtained by observing from equation 23 and 24 that the first terms of the equations are different and correspond to the effect of transverse applied loads and the second terms of these equations are identical and correspond to the Bragg reflection wavelength changes of the FBG induced by longitudinal strain. Therefore the Bragg wavelength width variation of the reflected peak due to transverse loading is Mastero (2005):…”

In this study, the response of a FBG-bonded-graphene plate at different applied stress location is demonstrated. The sensing element utilized for this purpose is a 35.9-mm FBG sensor bonded onto the surface of a graphene plate. The lateral displacement is changed with corresponding increase or decrease in the FBG’s curvature. The change in center wavelength of the reflected spectrum is almost linear, without a significant hysteresis effect. It was also observed that the sensitivity of the FBG changes for location of applied stress. Likewise, the area under the reflection curve is observed to increase with increase in strain level, indicating an increase total power reflected. This is verified by an increase in the voltage output as observed from the oscilloscope.
