 Sensor Description I.Hardware Integration Sensor FigureSensor NameDescription galvanic skin response (GSR) Skin conductance, also known as galvanic skin response (GSR) is a method of measuring the electrical conductance of the skin, which varies with its moisture level. Pulse and Oxygen in Blood (SPO2) Pulse oximetry a noninvasive method of indicating the arterial oxygen saturation of functional hemoglobin. Body Position The Patient Position Sensor (Accelerometer) monitors five different patient positions (standing/sitting, supine, prone, left and right.) Glucometer Glucometer is a medical device for determining the approximate concentration of glucose in the blood. The meter displays the level in mg/dl or mmol/l. Body temperature Body temperature depends upon the place in the body at which the measurement is made, and the time of day and level of activity of the person. Different parts of the body have different temperatures Page 6

 Way of Communication I.Hardware Integration Request Char Sensor to be used Functions to be called ‘A’ GSR float conductance = eHealth.getSkinConductance(); float resistance = eHealth.getSkinResistance(); float conductanceVol = eHealth.getSkinConductanceVoltage(); ‘B’ Body temperature float temperature = eHealth.getTemperature(); ‘C’ Body Position uint8_t position = eHealth.getBodyPosition(); eHealth.printPosition(position); ‘D’ SPO2 eHealth.getBPM() eHealth.getOxygenSaturation() ‘E’ Glucometer uint8_t numberOfData = eHealth.getGlucometerLength(); Page 7

 Pebble Smart watch III.System Implementation 1)Function in Android 2) Display on Pebble Page 17

1) Arduino:  Excellent choice for conducting this project.  Completed Library and easy language  Plug and play Feature  Great potential for development of medical system  Low cost  Good extensibility Conclusion Page 18

2) Bluetooth:  Meet the system requirement  Communication range  Low cost  Convenient for future development  compatibility Conclusion Page 19

3) Java:  not an appropriate language for serial communication  Input stream reading:  Byte hex  Better to combine with other language such as C.  Good in development of interface and multimedia Conclusion Number of read byte: 30 Number of read byte: 5 Number of read byte: 25 Number of read byte: 13 Number of read byte: 17 Number of read byte: 22 Number of read byte: 8 Page 20
