Abstract: A flexible and low-cost optical fiber transducer based on light attenuation by microbending was designed for the measurement of angular displacements. The transducer was tested for predetermined rotations, presenting a higher sensitivity for angles >10° by spacing the periodicity of the deformers by 2 mm. In addition, the performance on the measurement of angles <10° was also enhanced by the specklegram analysis, yielding to a linear response. Furthermore, the glove-mounted sensor was applied on the detection of the proximal interphalangeal joint, by performing the calibration by artificial neural networks, resulting in calculated angle values compatible to the nominal ones. © 2012 SPIE.
