Abstract

Disclosed are a sensor fiber and a method of manufacturing the same. The method of manufacturing a sensor fiber comprises providing a mixture solution including a detection member, submerging a core fiber in the mixture solution, and coating the detection member on a surface of the core fiber by stirring the mixture solution in which the core fiber is submerged. The detection member comprises a transition metal chalcogenide.

First claim

What is claimed is:

1 . A method of manufacturing a sensor fiber, the method comprising:
providing a mixture solution including a detection member; submerging a core fiber in the mixture solution; and coating the detection member on a surface of the core fiber by stirring the mixture solution in which the core fiber is submerged, wherein the detection member comprises a transition metal chalcogenide.

2 . The method of claim 1 , wherein the transition metal chalcogenide comprises molybdenum sulfide (MoS 2 ) or tungsten sulfide (WS 2 ).

3 . The method of claim 1 , wherein the core fiber comprises at least one of a polymer fiber, a natural fiber, a metal fiber, an inorganic fiber, or a composite fiber thereof.

4 . The method of claim 3 , wherein the core fiber is provided in plural, the plurality of core fibers are interwoven into a woven fabric or are braided into a braided fabric.

5 . The method of claim 1 , wherein the detection member further comprises at least one of a metal nanoparticle, a graphene, a graphene derivate, a metal oxide, or a conductive polymer.

6 . The method of claim 1 , further comprising, before submerging the core fiber in the mixture solution, coating an adhesive member on the surface of the core fiber,
wherein the detection member is coated on a surface of the adhesive member when the mixture solution is stirred.

7 . The method of claim 6 , wherein coating the adhesive member on the surface of the core fiber comprises:
providing an adhesive solution that includes the adhesive member; submerging the core fiber in the adhesive solution; and coating the adhesive member on the surface of the core fiber by stirring the adhesive solution in which the core fiber is submerged.

8 . The method of claim 6 , wherein the adhesive member comprises polydopamine, BSA (Bovine Serum Albumin), beta-amyloid, polylysine, chitosan, or any other polymer adhesives.

9 . A sensor fiber, comprising:
a core fiber; an adhesive member surrounding a surface of the core fiber; and a detection member surrounding a surface of the adhesive member, wherein the detection member comprises a transition metal chalcogenide.

10 . The sensor fiber of claim 9 , wherein the transition metal chalcogenide comprises molybdenum sulfide (MoS 2 ) or tungsten sulfide (WS 2 ).

11 . The sensor fiber of claim 9 , wherein the detection member further includes at least one of a metal nanoparticle, a graphene, a graphene derivate, a metal oxide, or a conductive polymer.

12 . The sensor fiber of claim 9 , wherein the adhesive member comprises polydopamine, BSA (Bovine Serum Albumin), beta-amyloid, polylysine, chitosan, or any other polymer adhesives.

13 . The sensor fiber of claim 9 , wherein the core fiber comprises at least one of a polymer fiber, a natural fiber, a metal fiber, an inorganic fiber, or a composite fiber thereof.
