Remotely programmable architecture of a multi-purpose physiological recorder

Wearable recording devices are widely used in home care monitoring or follow-up of high-risk or chronic patients. This paper presents a flexible architecture of multi-purpose physiological signal recorder. The recorder supports wired and wireless body sensor networks and features remote programmability of a wide-range of hardware settings, data processing and reporting options and dynamic linking of libraries. The recorder is based on a three-layer architecture including data acquisition, processing and communication modules. The design is not dedicated to a particular purpose, and thus any remote diagnosis based on variety of spontaneous physiological signals (e.g. ECG, EMG) may be performed. The configuration of all three layers is independently controlled by the software and thus allows for real-time reconfiguration of sensors, processing level and report content.
