Abstract
The capacitive coupling of at least two electrodes with an electrically conductive body may be determined when an AC voltage is applied to each of the electrodes and the currents flowing from each of the electrodes are measured. The currents flowing from each of the electrodes are measured n times, when n≧2, while different AC voltages are applied to the electrodes for each of the measurements. The coupling capacitances are calculated in a network analysis using the respective current and voltage values of the n measurements.
