AbstractIn recent years, utilization of mobile devices for tracking health parameters has increased. These devices are able to monitor different parameters such as heart rate, respiration patterns, amount of activity and energy expenditure. The devices specialized for medical applications provide more accurate measurements, assisting medical decision-makings and diagnosis procedures. This thesis work presents the development of an ambulatory health monitoring system for measuring heart activity, respiration and movement. The developed system consists of a measurement unit, an Android application and a computer software. The measurement device, along with capturing the data from the required sensors, is also able to locally store and/or transmit the data wirelessly to a hand-held device. The designed Android application is responsible for receiving this data, reconstructing it and visualizing it in real-time. The computer software is developed to extract the locally stored information after the recordings. The electronic design of the measurement unit is thoroughly described and the limitations are explored. Additionally, the structure of the implemented embedded software is illustrated and justified. Some brief overview of the structure of the Android application and the computer software is also provided. The signal quality achieved by the system was evaluated and the power consumption was measured for different use cases. Our results showed that the developed system provides a competing signal quality comparing to devices in the market. Additionally, it has been shown that transmitting the data via Bluetooth Smart is less power hungry than storing it to a memory card. The report is finalized by mentioning the challenges faced during the development process.
