Miniature high sensitive pH sensor based on micro optical fiber interferometer
A biocompatible pH sensor based on a Mach-Zehnder is proposed with the structure of SMF-TCF-SMF with a taper on the TCF portion. The sensor is then coated with PVA/PAA hydrogel which swells reversibly in response to changes to pH, which leads to a change of refractive index which translate to shifti...
