摘要:脈搏是心臟和心血管狀態等重要信息的外在反映,脈搏波中也包含著豐富的生理信息,所以準確得提取脈搏信號和脈搏波在醫學上有著十分重要的意義。本文設計了基于光纖光柵的脈搏傳感器,同時給出了脈搏信號的處理過程。該脈搏傳感器能夠克服電磁干擾等壓電傳感器的缺點,并且能夠織入服裝中,為智能服裝中利用光纖光柵檢測心音提供了基礎。通過實驗表明,該脈搏傳感器能夠準確得采集脈搏信號,并描繪脈搏波波形,實驗誤差小于1次/分鐘。

Abstract: The pulse reflects the conditions of blood vessels and heart, and there are rich physiological information in the pulse wave as well. So it is of great medical significance for extracting the pulse information. In this paper, a pulse sensor based on FBG is designed and the process for the pulse information is described. The pulse sensor is able to overcome the shortcomings of piezoelectric sensors such as electromagnetic interference. It can be weaved into the clothes. The experiment shows that the pulse sensor is able to accurately acquire the pulse information and the pulse wave. The experiment error is less than 1 times/min.
Keywords: sensor technology; the smart clothing; the pulse sensor; Fiber Bragg Grating
