對傳統中醫而言，脈診是重要的診斷方式之一。中醫脈診除了給人们一種非常主觀及模糊難解的印象外，就在於把脈過程中，中醫師以食、中、無名指，於病人手腕寸、關、尺的位置，施以浮、中、沉力道的把脈手法。運用此一手法，可使醫師手指在病人的手腕皮膚上，產生不同的位移，同時在浮、中、沉不同的深度下，取得病人的脈象。而此脈診的定位方式，至今仍未清楚地發掘出來。本文提出一壓力感測器陣列裝置於一脈波測試平台，又提出一雙感測脈診儀。其中脈波測試平台用來測試壓力感測器陣列的穩定性和可靠度，同時得到三維脈波圖譜。而雙感測脈診儀，可以進行三部九候脈診的量測，以模擬中醫師把脈的手法，取得三部九候的九個三維脈波圖譜。此圖譜不僅代表中醫師指下感覺的量化數據，也可求得其六個核心特性參數，包含脈的力道、脈率、脈長、脈寬及脈的上升、下降斜率。從成對樣本t-測試的結果，可指出在相隔10分鐘，於相同把脈位置，前、後取樣所得兩脈波的六個參數，沒有明顯差異，顯示壓力感測器陣列的穩定性和可靠度。由變異數分析的結果，可知在不同的按脈深度，脈波的六個參數除脈率外，其他參數值都不相同，顯示按脈深度具有臨床意義。由三部九候的三維脈波圖譜，可以顯示醫師指下對脈波的感覺，以發掘傳統中醫書籍中，以經驗為依據的手指脈象判讀的模型。

Pulse diagnosis is one of the most important examinations in Traditional Chinese Medicine (TCM). Regardless the fact of the subjectivity and fuzziness of pulse diagnosis in TCM, the displacement of Fu (superficial pressure), Zhong (medium pressure), Chen (deep pressure) at the location of Cun (upper), Guan (medium), Chi (lower) on the wrist during pulses diagnosis is still under discovering so far. In this paper, a Pressure Sensor Array assembled with a pulse testing platform was provided and a Bi-Sensing Pulse Diagnosis Instrument (BSPDI). The pulse testing platform is used to test the stability, reliability of the Pressure Sensor Array and obtain three-dimension pulse mapping (3DPM). On the other hand, BSPDI can go on measuring THREE POSITIONS and NINE INDICATORS (TPNI) to simulate the pulse taking methods of the TCM’s doctor and be obtained the nine plots of 3DPM from TPNI. The 3DPMs are not only presented the quantized data of the finger-feeling of TCM’s doctor but also identified the core characteristics of 3DPM, including strength, rate, length, width and trends. The results of a paired samples t-test reveal that the six core characteristics of the two pulses obtained from the Pre- and Post-sampling, during the 10-minute period and on the same pulse-taking position, there are not distinct differences which present the stability, reliability of the pressure sensor array. ANOVA indicate that, the six core characteristics except RATE, the differences of the core characteristics exist among different pulse taking depths. The results reveal that there are some clinic meanings consistent with the pulse-taking depths. From the 3DPM of the TPNI, the finger-feeling of the pulses of the TCM’s doctor can be displayed to discover the empirical finger-reading models published in the TCM books.
