Abstract
A relative humidity (RH) sensor based on a V4C3 MXene-coated etched single-mode optical fiber is experimentally demonstrated. We fabricated and tested RH sensors with four different diameters of 15, 16, 17, and 18 μm for the optimization of etching thickness in terms of hysteresis. It was shown that the RH sensor with a 17 μm diameter delivered the most repeatable performance with the lowest hysteresis during both RH rising and falling processes. The operating RH range for the sensor was from 30 to 80%. The sensor demonstrated fast response and recovery times of 0.125 s and 0.386 s, respectively, suggesting its potential for real-time breath monitoring.
