All Polymer Optical Fiber Sensor for Dissolved Oxygen in Fish Farms

Abstract

We present an all-polymer optical fiber sensor for the measurement of dissolved oxygen. The sensing matrix containing oxygen-sensitive PtOEP, is of the same polymer as the optical fiber core, leading to increased robustness.

Chromogenic Approach for Oxygen Sensing Using Tapered Coreless Optical Fibre Coated with Methylene Blue

“…Studies have optimised these sensors by selecting better solvents and incorporating antenna dyes to enhance sensitivity and accuracy [28]. All-polymer optical fibre sensors have been developed for specific uses like monitoring dissolved oxygen in fish farms [29]. Multi-point sensors based on laser absorption spectroscopy have been created to measure oxygen at different points simultaneously [30], and temperature compensation mechanisms have enabled real-time gas detection [31].…”
