In this paper we propose an analyzing of the response of
a stress optical fiber sensor of which we proposed several design.
We show that an optical fiber sensor with these designs can covenanting allow
the measuring the force/stress applied to a mechanical structure or which it is
linked, by optimizing the uses of appropriate materials for constituting the
sensor support. The experiment that we introduce to validate our approach based
in principles includes design with a support bearing a multimode optical fiber organized
in such a way that the transmitted light is attenuated when the fiber-bending
angle coming from stitching in holes of the support is modified by the effects
of the force/stress applied to the optical fiber sensor realized in this way.
The tests realized concern the most relevant parameters that define the performances
of the stress sensor that we propose. We present the problems that we to solved
for the optimization of the sensor for selecting the more efficient material
for the optical fiber sensor support related to a relevant choice of optical
