Abstract
A measurement device including a fastener for use in attaching a first member to a second member, in which the fastener has an aperture extending through a length of the fastener, and a first optical fiber located within the aperture, in which the first optical fiber includes at least one fiber Bragg grating sensor. At least a portion of the first optical fiber can be secured within the aperture. A first end of the first optical fiber can be connected to an associated first optical connector and a second end of the first optical fiber can be connected to an associated second optical connector.
