ABSTRACT:
For determining the respective geometrical position, the displacement or angle of a body by capacitive sensing, a supply voltage applied to a voltage-distribution element is switched, and/or phase-shifted voltages are applied, in such a way that at least two different distribution patterns of the supply voltage, that follow each other in time, are obtained across the voltage divider.
