The students have practical experience with and knowledge about:

  • Circuit technology of biopotential amplifiers.
  • Sensor technology (pressure, volume flow, gas analysis).
  • Working with Real-Time-Matlab/Simulink.
  • Signal processing.
  • The experience of physiological basics on the own body.


The practical course deepens the lecture Biomedical Systems I in 4 experimental blocks.

  • Measurement of Biopotentials: Differential amplifier, instrumentation amplifier, isolation, filtering, registration of ECG, EMG and EEG on the own body.
  • Spirometry and respiratory gas analysis: Spirometric basic data will be collected at a clinical workplace. Furthermore, the energy conversion in the body will be measured and the efficiency of cycling will be determined.
  • Automatic blood pressure measurement: Using an electric air pump, a blood pressure cuff with microphone, a pressure sensor and electromagnetic valves, a Matlab/Simulink-based automatic blood pressure measurement system according to Riva-Rocci-Korotkoff has to be developed. The performance will be compared with that of a commercial device in some harmless provocation tests (Schellong test, Valsalva manoeuvre, physical work).
  • Signal processing with Matlab/Simulink using the ECG as an example: determination of heart rate, investigation of heart rate variability in time and frequency domain, interference suppression by adaptive filtering.
