A Universal Tool for Mobile Long-Time Recording, Monitoring and Analysis of Bio-Signals

While monitoring and analysis of bio-signals are essential in today’s medical diagnostics, it is gaining even more importance with modern computer systems allowing the use of complex real-time algorithms and analysis of huge amounts of data. To ease development of such algorithms, a tool is needed which allows the mobile long-term recording of signals at reasonably high frequencies and at the same time provides a framework for a straightforward implementation of all kinds of real-time monitoring, analysis and visualization algorithms. The Measure tool developed at femu, RWTH Aachen University, consisting of a mobile data logging device and an easily extendable PC software, addresses this problem. The system has been evaluated in a case study analyzing gastrointestinal motility.
