This communication reports on a novel intensitybased optical fiber strain sensor. A conventional multimode fiber was drawn-down to give a reduced cross section that resembled a symmetrical taper. The sensors were embedded into glass fiber reinforced epoxy composites and the light transmission characteristics through the profiled optical fiber was measured as a function of applied stress. A linear response was observed. Index Terms-Optical fiber, paper, strain sensor composites.
