Encapsulation of fiber optic strain gauges with adhesive
new method for mounting fiber optical strain gages to structures will be proposed which is fast, easy and reliable. Mounting of the sensors happens by means of a specially designed mounting tool called a UV sensor pad. The achievable performances with four different types of adhesives (three urethane and one epoxy adhesive), and with different fibre types, are evaluated: acrylate-coated, polyimide-coated, and bare single-mode optical fibres. Experimental measurements based on the Mach–Zehnder interferometric technique were performed to validate the theoretical prediction and reveal the differential strains between the optical fiber strain sensor and test specimen.

Fiber Bragg Grating Strain Desensitization
To address the issue of extra-large structural deformation or strain in infrastructures such as bridges, buildings, railroads, and pipelines during catastrophic events, this study proposes a wide-range fiber Bragg grating (FBG) strain sensor utilizing a snake spring. This research focuses on a desensitization method to develop a wide-range FBG sensor for extra-large strain monitoring, which is an essential requirement in large scale infrastructures or for some special occasions. Under appropriate hypotheses, the strain transfer distribution of wide-range FBG. Fiber Bragg grating (FBG) sensors, a relatively new fiber-optic technique where struc-tural strain influences the peak wavelength of the reflected wave from in the FBG, consti-tutes an inscribed Bragg grating and encapsulated protective packaging.
