摘 要
近年來生物晶片的發展提供許多新的生物量測方式，也是未來實現病患居家量測的重要方向。不過雖然生物晶片能將反應的環境縮小，但後端還是需搭配相對的量測與傳輸裝置，方能實現一套可靠的居家量測系統。有鑒於此，本研究將以阻抗量測為基礎，開發一套可攜式的生物晶片量測裝置，同時搭配病患健保卡的身份判讀，可與雲端系統連接，並進行量測結果的紀錄、追蹤與警告。本研究所設計之阻抗量測模組，可量測範圍200kΩ至1.4MΩ，並擁有回授校正功能來計算最佳增益，將誤差調整至3%之內。此外，為避免不同量測地點的環境影響，如濕度或溫度；模組也設計了自我校正功能，啟動時會以標準電阻進行各項測試並調整內部參數。量測裝置可結合病患健保卡的讀取，在幾乎免手動輸入資料的情況下，自動將病患資料傳輸至雲端系統。醫護端則可透過資料庫長期追蹤病患狀況，並適時提醒患者回診。
關鍵詞：阻抗量測模組、回授校正、自我校正、雲端系統
Abstract
In recent years, Biochip developments have provided many ways to measure biological information. It is also an important orientation to achieve the home care system in the future. Though Biochips could reduce reaction environments, it required reliable measurements and transmission equipments to achieve a home care system. In this study, a biochip of impedance measuring device is developed on the basis of impedance measurements. It works with the identification of national health insurance card (NHIC) of patients and it can be connected with Cloud System for recording, tracking and warning of measurement results. The range of impedance measurement device is from 200kΩ to 1.4MΩ. Moreover, it has Rectified Feedback (RBF) to calculate the best benefit of measurements and to control error rates within 3%. To avoid environmental effects raised in different locations, e.g. humidity or temperature, we designed a self-calibration function started by a standard resistor to adjust and test the internal parameters. The design could be combined with NHIC recognition and upload the patient’s data to the Cloud System automatically without any manual input. Therefore, with this device, Medical Personnel could remind the patients of their clinic schedule through a long-term tracking.
