本論文提出一個應用於尿酸檢測平台之電化學生物感測器信號處理系統設計，其主要目的是要設計一個簡易使用的尿酸檢測平台，透過pH感測試片，對於尿液檢體進行檢測，將檢測結果所回饋之電壓信號，經由所開發之信號處理系統，將測得結果以無線傳輸至手機，最後，透過手機之APP將pH值顯示出來。在系統設計方面，我們採用EMF32微處理器晶片為控制核心，並採用超極生技公司之pH感測試片，將待量測之尿液檢體滴在試片上，而該試片會將檢測結果反應出電壓信號，透過晶片內之ADC接收後，轉變為數位訊號，再經由UART傳出訊號給藍芽模組，藍芽接收到訊號後再以無線方式傳送到手機，最後，由手機APP顯示數值即可得知尿酸之pH值，同時，這個檢測結果也會傳送到雲端資料庫中。在系統驗證方面，我們採用pH感測試片針對不同pH標準液進行量測，將所測試結果，建立出pH值之校正曲線，並將檢測結果與商用酸鹼檢測儀之檢測結果進行比較驗證。實驗結果顯示本論文所提出之尿酸檢測平台，具有檢測速度快、操作簡便、與高準確度等特點。

In this paper, an electrochemical biosensor signal processing system for uric acid detection platform is proposed to detect the pH value of urine. In the proposed platform, the measured urine is dropped on a pH sensor strip, and the strip will generate a voltage value corresponding to the measured urine pH value. Then, the voltage will be transmitted to the phone in wireless after measured by the proposed signal processing system. Finally, the pH value of the measured urine will be shown on the phone and be recorded in the cloud. In the system design, the EMF32 chip is used as the control unit, the UltraE pH strip is used for urine pH measurement, the Bluetooth module is used to perform the wireless data transmission, and the phone is used to show the measured results. In the system verification, we use the UltraE pH strip to measure a set of different pH standard solution to establish a calibration curve. Based on the calibration curve, the proposed system can perform the urine pH measurement. In comparison with the results measured by the commercial acid-base detector, the proposed system has the advantages of high speed, small size, simple operation, and easy portability.
