Abstract
A capacitive sensor system has a receiving electrode with a capacitive coupling to a ground plane or ground electrode, a first transmission electrode arranged between the receiving electrode and the ground plane and having a size with respect to the receiving electrode such that the transmission electrodes covers a surface area of the receiving electrode, and a second transmission electrode arranged adjacent to the receiving electrode and which is not coupled with the first transmission electrode, wherein the second transmission electrode is driven with a higher alternating voltage than the first transmission electrode.
