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.

基于V4C3 mxene涂层蚀刻光纤的相对湿度传感器

实验证明了一种基于V4C3 mxene涂层蚀刻单模光纤的相对湿度传感器。我们制作并测试了直径分别为15、16、17和18 μm的RH传感器，以优化蚀刻厚度。结果表明，在RH上升和下降过程中，直径为17 μm的RH传感器具有最高的重复性和最低的滞后。传感器的工作相对湿度范围从30到80%。该传感器的响应时间和恢复时间分别为0.125 s和0.386 s，表明其具有实时呼吸监测的潜力。
