Claim 17:
18. A system for sensing at least one condition proximate the system, the system comprising:
at least one optical fiber comprising a distal end, a plurality of fiber Bragg gratings along a length thereof, and a proximal end;
a plurality of sensor materials coupled to the at least one optical fiber and surrounding and in contact with respective fiber Bragg gratings of the plurality of fiber Bragg gratings, wherein at least one sensor material of the plurality of sensor materials comprises a pre-stressed corrodible material that causes a respective fiber Bragg grating around which the at least one sensor material is disposed to be in axial tension or compression; and
a light wavelength sensor coupled to a proximal end of the at least one optical fiber, the light wavelength sensor configured to sense a wavelength of light reflected from the plurality of fiber Bragg gratings.
