High Sensitivity Pressure Sensors Utilizing Advanced Polymer Coatings

Abstract

We report a high sensitivity pressure sensor utilizing optical fibers coated with novel polymers. Pressure sensitivity of 5 pico-m/psi for the fiber Bragg grating based and 155 dB radian/micro-Pa for interferometric sensor is reported.
