The FPI was fabricated with UV-curable resin between the CYTOP and a silica pigtail, which provides flexibility and the possibility in situ fabrication. In this case, the FPI is an edge-filter for the FBG response, which presents both wavelength shift and optical power attenuation as the bending angle increases. A dynamic compensator for the material's viscoelastic response resulted in a six-fold reduction in the sensor's transient response error. The FPI-POFBG angular movement sensor was validated in knee angle monitoring during gait cycles, where the sensor presented errors as low as 2.5°. This is a low-cost sensor with high flexibility on fabrication and with the capacity of following subtle angle variations, as the ones commonly occurred in gait cycles. | URI: | https://hdl.handle.net/20.500.14279/19329 | ISSN: | 15581748 | DOI: | 10.1109/JSEN.2020.2974931 | Rights: | © IEEE. | Type: | Article | Affiliation : | Federal University of Espirito Santo Cyprus University of Technology University of Aveiro |
