Nowadays smartphones and tablets (later mobile devices) have wide variety of sensors, communication ports and a high-quality display, beside they have powerful hardver support. The great advantage is that numerous applications can be developed to these devices.Furthermore, through the small size of mobile devices, portability does not cause any problem, not to mention the fact that they are capable of substituting some practical embedded systems.
Physiological measurer systems not only communicate with one special processor, but they can communicate via several standardised ports (e.g. USB, Bluetooth) with any device. Conseqently, mobil devices can receive these physiologal signals, and use for different operations. On the other hand, mobil devices have to know the protocol of measuring devices' protocol, beause it is inevitable of understand the received data.
Nowadays there are only target specific health monitoring systems (e.g. Holter monitor) with the worst disadvantage that they cannot be expanded with new functions. On the contrary, mobile device applications are able to perform health monitoring functions, besides complementing them with new functions. My thesis connect to this field within I developed two health monitoring application for Android based devices.
The first application trying to display the physiological signals in real-time. In relation with this I studied the possible technologies. While the development I reached the system border with the help of current Android technologies. Finally the application can show the physiological curves closely like the quality of intensive care units.
The aim of the second application is to record the measured data and send it as e-mail attachment through the Internet. The application's requirement are the follows: user-friendly platform, automatic data transmission and fault tolerance regards the system.
