Impedance measurement of a forearm with the Sciospec Medical Research ISX-3 impedance analyzer

The Medical Research ISX-3 impedance analyzer is intended to facilitate the use of impedance spectroscopy in medical research applications. To that end it includes measures for enhanced electrical safety including medical grade isolation enabling a safe operation of the instrument in medical research settings.

This very simple experiment shows the impedance change in the forearm due to a movement of the hand. The direct response in impedance is visible in the live-plotter of the data (absolute impedance and phase).


  • Medical Research ISX-3 with a 32-channel multiplexer
    • only 4 channels were used
  • 4-point measurement
  • Adhesive electrodes (ECG-electrodes) Ambu Bluesensor NF NF-50-A/12
