Design of a versatile low cost mobile health care monitoring system using an android application

A continuous monitoring of the biomedical signals of the human body such as ECG, blood pressure, SaO2, and temperature is necessary in the treatment of chronic diseases. The treatment depends directly on the evolution of these signals. Being necessary an ambulatory health care system, in order to have biomedical data at any moment and anywhere. Android OS is a powerful tool able to process, store and visualize biomedical signals. The system presented in this paper is a device energized with rechargeable batteries, able to measure the four signals previously mentioned and send them wirelessly, without missing data, to the Android device in order to be visualized, stored, and to finally, to be shared with a specialist.
