Abstract
A capacitive sensor () includes a capacitive sensor field (), the capacitive sensor field () having a plurality of discrete electrodes () which are coupled to discrete leads (). The leads () of a first electrode () are guided such that they are capacitively coupled with at least one second electrode (). A first signal (Cm) is detected at a first lead () which is coupled with the first electrode (), and a second signal (Cm) is detected at a second lead () which is coupled with a second electrode (). The capacity (Cf, Cf) of the first electrode () or of the second electrode () is determined using a predetermined calculation formula which takes the first signal (Cm), the second signal (Cm) and the capacitive coupling between the second electrode () and the first lead () coupled with the first electrode () into account.
