Abstract

Wireless sensor networks on human body have become essential in the field of patient monitoring. The fact that completely non-invasive sensors can be used attached on clothes, facilitates measurements in daily tasks. The aim of this paper is to demonstrate the approach we followed upon developing a generic and flexible patient tele- monitoring system based on custom sensor devices and a communication control unit (CCU). A sensor device consists of the measurement control part (microcontroller) and the sensing part (be it commercial or homemade sensors). The CCU plays the role of the master device of the wearable network and is based on a microcontroller and a Bluetooth module. The CCU scans all possible attached sensors on the bus of the network and constructs XML files based on the sensor devices and the network structure. In addition a software suite has also been developed in order to i) manage the different protocols and projects, ii) manage the operating system service and iii) provide different representations/visualizations of the signals (online or offline) in 2D graphs, FFT or 3D human model in the appropriate environment. At the PC side, the operating system service utilizes the XML descriptions in order to acquire the measurement from the CCU and store them in a database. The usefulness of the system is demonstrated through a set of conducted experiments, while the importance of the approach is discussed in the light of recent published literature.
