Abstract

Widespread use of smart structures technology in industrial and commercial applications requires significant reductions in systems cost and complexity. For knowledge and control of the shape and vibration of structures, one would ideally employ a number of discrete strain sensors placed at critical locations. One significant advantage of optical fiber sensors is that they can be multiplexed along a single fiber and be individually addressed, greatly simplifying the ingress-egress- connection problems. Multielement strain sensor arrays have been fabricated during the drawing of an optical fiber from a preform at a sustained rate of approximately equals 2,000 per hour. These arrays have been surface- mounted and embedded in composites, and distributed static and vibrational strain measurements have been made. This paper will report recent developments and improvements in this low-cost technique for fabricating and applying strain sensors for smart structures applications.
