本研究應用新崛起的Web服務 (Web Service)、藍芽通訊技術 (Bluetooth) 及GSM簡訊服務 (GSM Short Message Service)，發展一套適用於居家環境之新型健康照護系統。我們首先製作一個行動式心電圖感測發收單元 (ECG Sensor/Transmitter/Receiver)，接著我們利用藍芽模組將數位化後的心電圖(ECG)訊號傳至心電圖接收器 (ECG Receiver)，再經由簡單物件存取協定 (SOAP) 傳給遠端健康照護Web服務 (HealthCare Web Service) 系統之資料庫中，藉此醫師可以透過網站伺服器檢視病患心電圖進行診斷。若醫生診斷後認為病人需要進一步檢查，則可使用簡訊Web服務 (SMS Web Service) 發送簡訊通知病人就診。 本系統的軟體架構具有良好的擴充性，因此容易維護，亦可大幅降低系統整合及後續開發成本。另外透過藍芽技術的應用，本系統亦可大幅減少家中纜線的羈絆並增加機動性。實驗的結果驗證本系統有良好的效能，具備實用的價值。

This study presents a novel home healthcare system using the emerging Web Service, Bluetooth, and GSM short message service. We first implement a mobile ECG unit, which consists of a sensor, transmitter, and receiver. After the digitization process, the measured ECG signal is transmitted to the ECG receiver via the wireless Bluetooth module. Then, the ECG signal is passed along the Internet to the remote database of the healthcare Web Service unit based on the SOAP for diagnosis. The patient will receive the GSM short message from the doctor if further diagnosis is necessary. Since the software structure of the proposed system is very easy to expand and maintain, it can significantly reduce the costs required for future integration and development. Besides, the use of Bluetooth allows the residence to escape from the fetters of interconnection wires, thereby increasing system mobility. Experimental results verify the effectiveness of the proposed system for practical application.
