Abstract: Systems and methods for sensing an external measurand are disclosed. A sensor includes an optical fiber having at least one fiber Bragg grating (FBG) section and a plurality of carbon nanotubes (CNTs) surrounding at least a portion of the FBG section. Light is provided into the sensor while the CNTs are exposed to one or more measurands. A change in a spectrum of one of a transmitted portion and a reflected portion of the light is determined. A measurand that has caused the change is identified.
