摘要：

为在服装中实现人体脉搏监测的功能，提出了将光纤布拉格光栅作为脉搏传感器的方法，并以针织复合组织为基础，采用空气层与其他组织相结合的织物结构，制作脉搏传感织物。该织物采用棉纱在Stoll CMS-320型电脑横机上进行编织，并利用针织物延伸性好以及回弹性好的优点，将光纤布拉格光栅传感器植入到织物的空气层中。为验证脉搏传感织物的检测效果，使用红外脉搏传感器与该脉搏传感织物同时进行脉搏检测，实验结果表明，该脉搏传感织物可以低失真度的检测到脉搏波，可以实现光纤布拉格光栅传感器的封装，同时也可以更换传感器，满足服装洗涤要求，且不影响穿着舒适性。

Abstract:

In order to monitor the pulse of the wearer in the garment, in this study, a way was proposed to produce a fabric sensor by integrating fiber Bragg grating sensor into a composed knitted structure, which was special designed by combining the air layer stitch and jacquard stitches. The compose structure is knitted with cotton yarns on a Stoll CMS-320 computerized flat knitting machine. Then, by taking advantages of good extensibility and elasticity of knitted structures, the fiber Bragg grating sensor was implanted into the structure and a sensing fabric was produced finally. For evaluating the effectiveness of the pulse sensing fabric, a test was conducted and the infrared pulse sensor was also involved for comparison. Analysis of test results reveals that the pulse sensing fabric has good stability and reliability in detecting wearers' pulse, and it is also washable and comfortable.

Key words: pulse detection, fiber Bragg grating sensor, knitted fabric, air layer composite stitch
