陣列式高分子感測器應用於橈骨動脈之脈波量測

The Pulse Measuring on Radius Artery using Polymer Array Sensors

指導教授 : 吳明川

摘要


本研究研製一造價低廉的陣列式高分子感測器,此感測器係由導電性高分子聚合物、銅箔片與矽膠所製作而成,利用高分子材料電阻特性,來量測人體手腕橈骨動脈的徑向微小震動。 本文將陣列式高分子感測器結合硬體電路,將量測到的脈搏訊號作訊號平均、放大、濾波等處理,並透過資料擷取卡匯入電腦分析,建構一套非侵入式脈波量測系統。時域上,可顯示脈搏波形,並從中分析得脈搏強度與頻率等資訊;頻域上,透過快速傅立葉轉換,擷取其前十個諧波,依其相對數值比例之大小做為身體健康評估的依據。

This research develops a low cost polymer array sensors. The sensor is composed of conductive polymers, copper foil and silicone. We use resistance characteristics of polymer materials, to measure the vibration of radius artery. This research combines our sensor with hardware circuit, the measured signal for the average, amplification, filtering and other processing to develop an non-invasive measuring system. In time-domain, we can analyze the pulse to know the strength and frequency. In frequency-domain, we use FFT (Fast Fourier Transform) to find the first ten harmonic waves and estimate for the health according to the harmonic waves.
