Physiological Measurements Facility is located in the Sähkötalo, campus area of Tampere University of Technology (TUT), and in the FinnMedi 1 building, next to Tampere University Hospital. We have several equipment for bioelectrical, like ECG, EEG and bioimpedance, measurements.

We also have expertise on processing and analysis of physiological signals.


  • recording and analysing bioelectric and biomechanical signals
  • ECG, EDA (GSR), EEG, EGG, EMG, EOG, Force, Pressure, Strain, Flow, Temperature, Sound, Light
  • filters (FIR and IIR), spectral analysis and histograms
  • export data to MatLab, LabVIEW, and MS Excel/Word


  • true differential 4-terminal connections
  • 1 μV, 1 pA sensitivity
  • impedance range 10 Ω to > 1 G Ω
  • up to 750 kHz frequency range

Impedance Pneumography

  • light, ambulatory, long-term physiological measurement device
  • dimensions 51x83x15 mm, weight 83 g, 24 h recording time
  • one channel four-electrode impedance pneumography measurement with 256 Hz
  • one channel ECG measurement with 512 Hz
  • tri-axial acceleration measurement with 30 Hz
  • 2 GB memory, < 1 mA current at 100 kHz


  • EEG measurements up to 512 channels and sampling rates up to 20 kHz
  • impedance testing with visual display with values for each electrode
  • online data processing including DC offset removal, filtering, re-referencing, montage selection, etc.
  • online averaging, FFT, wavelets, source reconstruction, etc.
