Stress Sensing by an Optical Fiber Sensor: Method and Process for the Characterization of the Sensor Response Depending on Several Designs

Abstract

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 fi</span><span lang="EN-US">ber-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 per</span><span lang="EN-US">formances 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 fibers.</span><span lang="EN-US"> <o:p></o:p></span> </p

Review of Wearable Sensor-Based Health Monitoring Glove Devices for Rheumatoid Arthritis

“…An optical sensor uses the characteristics of optical technology to determine the curvature angle of a bend [ 64 ]. The sensor measures infrared (IR) light emitted from a diode transmitted through a fiber core to a detector (photo diode) [ 64 , 65 ], as shown in Figure 9 . When the fiber core is bent, the photo diode experiences changes in the received light within the signal processing circuitry (Vo).…”
