Abstract
A capacitive sensor device for detecting the presence of a human body part in a detection region of the sensor device is disclosed. The sensor device includes a first sensor electrode with a first electrode section, a second sensor electrode with a second electrode section, and a measuring device for ascertaining a measurement variable, which is based on a current difference between a first current flowing in the first electrode section of the at least one first sensor electrode and a second current flowing in the second electrode section of the second sensor electrode. The measuring device has an electric coil, and the first electrode section of the first sensor electrode and the second electrode section of the second sensor electrode are at least partly arranged relative to each other and relative to the coil in each case and are coupled to the coil.
