Paper Abstract

In this paper, we propose a novel and simple method to measure the force vector by bonding the uniform fiber Bragg grating along the erect main strain line of the structure. With the same direction but various magnitudes or with the same magnitude but different directions, the center wavelength and bandwidth may both change. Based on the different responses of the reflection spectrum, we can measure the direction as well as magnitude of various forces in theory. We also offer some elementary experiment results to demonstrate the feasibility of this sensing principle. The experimental results are in agreement with our theoretical analysis.
