IEEE. https://doi.org/10.1109/ICSENS.2013.6688291978-1-4673-4641-210.1109/ICSENS.2013.6688291https://academica-e.unavarra.es/handle/2454/52764In this work a new optical fiber pH sensor based on the deposition of poly(acrylic acid) (PAA) using the electrospinning technique is presented. The optical fiber structure consists of a 4 cm segment of hollow core fiber (50/150¿m) spliced between two standard multimode fibers onto which the nanoweb is deposited. The sensitive layer is a membrane composed by PAA nanofibers deposited onto the surface of an optical fiber. The sensor has a repetitive behavior and low hysteresis in the pH range 4-7, with an average sensitivity of 0,53 dB/pH.application/pdfeng© 2013 IEEE. Personal use of this material is permitted.
