Abstract
A glazing unit of a vehicle or building, which has at least one glass pane or polymer film, wherein a capacitive sensor is arranged on a first surface of the or a glass pane or polymer film, which sensor includes a first sensor section and a second sensor section spaced at a distance therefrom on the first surface, which second sensor section acts as a signal readout section, wherein during operation of the sensor, an electrical field is generated between the first and second sensor section, which field partially penetrates the glass pane or polymer film, wherein a material property compensation electrode is provided on the second surface of the same glass pane or polymer film, opposite the second sensor section.

A glazing unit of a vehicle or building, which has at least one glass pane or polymer film, wherein a capacitive sensor is arranged on a first surface of the glass pane or polymer film, which sensor comprises a first sensor section and a second sensor section spaced at a distance therefrom on the first surface, which second sensor section acts as a signal readout section, wherein during operation of the sensor, an electrical field is generated between the first and second sensor section, which field partially penetrates the glass pane or polymer film,
- wherein a material property compensation electrode is provided locally on the second surface of the same glass pane or polymer film, opposite the second sensor section, and
- wherein the glazing unit comprises a first connecting line that is connected to the first sensor section to apply a first potential to the first sensor section and a common second connecting line that is connected to both the second sensor section and the material property compensation electrode to apply a same second potential to both the second sensor section and the material property compensation electrode.
