Abstract

The embodiments are related to a sensor, a sensing system, and a sensing method, which may be used for sensing multiple measurands (e.g., gases or temperature variations), hi an embodiment, the sensor may include a fiber Bragg grating and a coating material coated, either on n cladding or on a partially removed cladding of the fiber Bragg grating An interaction between a particular measurand (e.g., a gas such as CO2) and the coating material (e.g., poly allyl amine) may cause a change in the refractive index of the fiber Bragg grating. The sensor may detect the particular measurand based on the change in the refractive index of the fiber Bragg grating.
