Advanced sensing method in voltage maps measurement process

Our contribution focuses on the advanced method of the voltage-impedance map measurement involving a measuring probe optimization for the human skin voltage chart measurement. The conventional telescopic electrodes show significant disadvantages while placing them on non-plane surfaces. Depending on the covered shape the electrodes do not have sufficient contact to the skin in one case. In the other case the closest tips are pressed almost completely in, causing a significant higher force than the medium force does. To achieve a better coverage of any skin area and get a reduced force range of the 64 test tips a pneumatic kind of measuring probe - head has been implemented.
