A human body micro-circulation evaluation system includes a heartbeat cycle sensing unit, a micro-circulation sensing unit, a digital signal processing unit, a database, and an evaluation unit. The digital signal processing unit calculates a micro-circulation blood stream average function based on a reference cycle time of a heartbeat cycle signal outputted from the heartbeat cycle sensing unit that has sensed the blood circulation of a user under test, and a micro-circulation blood stream signal outputted from the micro-circulation sensing unit that has sensed a test portion of the user under test, and also calculates a micro-circulation characteristic set related to the user under test in the specific state based on the function value of the micro-circulation blood stream average function. The evaluation unit performs a comparison to statistic data set related to the micro-circulation characteristic set in the database, so as to obtain an evaluation result related to the health status of the test portion.一種人體微循環評估系統,包含一心跳週期感測單元、一微循環感測單元、一數位訊號處理單元、一資料庫及一評估單元。該數位訊號處理單元依據由該心跳週期感測單元感測受測者之血液循環後所輸出的一心跳週期訊號之參考週期時間,以及由該微循環感測單元感測受測者之一受測部位後所輸出的一微循環血流訊號,計算出一微循環血流平均函數,並依據該微循環血流平均函數的函數值,計算出相關於該受測者在該特定狀態下的一微循環特徵組。該評估單元在該資料庫中比對與該微循環特徵組相關的統計資料組,得到相關於該受測部位之健康狀態的一評估結果。1‧‧‧人體微循環評估系統11‧‧‧心跳週期感測單元12‧‧‧微循環感測單元13‧‧‧類比數位轉換單元14‧‧‧抗噪單元15‧‧‧數位訊號處理單元151‧‧‧訊號分段模組152‧‧‧正規轉換模組153‧‧‧函數計算模組16‧‧‧資料庫17‧‧‧評估單元
