Double-pass Mach–Zehnder fiber interferometer pH sensor
A biocompatible fiber-optic pH sensor based on a unique double-pass Mach–Zehnder interferometer is proposed. pH responsive poly(2-hydroxyethyl methacrylate-co-2-(dimethylamino)ethyl methacrylate) hydrogel coating on the fiber swells/deswells in response to local pH, leading to refractive index chang...
