This paper presents the design and prototype of a wireless health monitoring system using mobile phone accessories and to collect the medical data using the Bluetooth device. Bluetooth supports common usage with mobile computing devices. With the increasing number of cardiac patients, this design can be used for early detection of heart disease unlike most of the existing methods that use an optical sensor to monitor heart rate. The approach is to measure real-time ECG with dry electrodes placed on smart phone case. The collected ECG signal can be stored and analyzed in real time through a smart phone application for prognosis and diagnosis. The proposed hardware system consists of a single chip micro controller (RFduino) embedded with Bluetooth low energy, hence miniaturizing the size for the better enhancement.
Keywords : Bluetooth, Bluetooth Low Energy (BLE), electrocardiogram (ECG), heart, mobile, smart case.
