Abstract :
Prototype fiber-optic strain gauges consisting of plastic fibers containing permanent microbends were fabricated and various properties were measured. Their strain sensitivity as a function of microbend amplitude is shown, and their transduction mechanism, which is primarily the drop in microbend amplitude under tension and the corresponding increase in the fibers´ optical transmission, is discussed
