Abstract

A Fabry-Perot interferometer (FPI) based on a polymer micro-rod on the end-face of fiber core was fabricated for humidity sensing. The whole fabrication process by using the simple and low-cost drawing-curing method takes less than one minute. The diameter and height of the polymer micro-rod are only 9.2 μm and 11.3 μm, respectively. Because of its ultra-compact structure, the rise time and recover time of the sensor have been improved to 291 ms and 886 ms when the relative humidity of the environment changes between 61% and 76%. The proposed humidity sensor is expected to have important applications in bio-pharmaceutics, chemical industry, and environmental science, owing to its simple fabrication process, high sensitivity (659.67 pm/%RH), fast response and good stability.
