Patent ID: 8639066

Claim:
A fiber gas sensor comprising: a core fiber comprising at least one fiber Bragg grating defining at least one fiber Bragg grating region, an outer surface and a length; a fiber cladding in contact with the core fiber along the entire length of the core fiber, the fiber cladding having an outer surface and a length; and a sensing matrix structure disposed upon the outer surface of the fiber cladding along a portion of the entire length of the fiber cladding and surrounding the fiber Bragg grating region, the sensing matrix structure comprising a nano-structured trampoline matrix layer comprising a material having a high-coefficient of thermal expansion and a high thermal conductivity, wherein the sensing matrix structure is further comprised of a bonding layer and a capping layer, the bonding layer being disposed on an outer surface of the fiber cladding, the nano-structured trampoline matrix layer being disposed on an outer surface of the bonding layer, and the capping layer being disposed on an outer surface of the nano-structured trampoline matrix layer.
