The utility model discloses FBG (Fiber Bragg Grating) sensing fabric for pulse, heart sound and respiratory signal detection. The FBG sensing fabric comprises a pulse sensing element, inner-layer fabric and outer-layer fabric, wherein the pulse sensing element is formed by an FBG and a flaky polymer; a V-shaped groove is formed in the flaky polymer along a center line; the FBG is fixedly arranged in the V-shaped groove of the flaky polymer, and the elasticity of the flaky polymer is greater than that of the FBG; the flaky polymer is connected with the inner-layer fabric, and the grooving surface of the flaky polymer faces the inner-layer fabric; the elasticity of the inner-layer fabric is greater than that of the outer-layer fabric; a pocket is formed between the inner-layer fabric and the outer-layer fabric; the pocket is fully filled with filler which is made of a hard plastic material and has an arc outer contour, and the filler is fixedly arranged right above the flaky polymer. According to the FBG sensing fabric disclosed by the utility model, the FBG is combined with the fabric; the local pressure of the FBG is increased through a structure that two layers of fabric are filled with the filler, and the whole pressure on a wrist is reduced, and the wearing comfort is increased; compared with an electric pulse sensor, the detection sensitivity is increased.
