Abstract
A capacitive sensor device includes a printed circuit board (PCB) having a plurality of first vias and a plurality of first tracks connected with the first vias, a sensing device connected with the first vias, and a compensation device. The compensation device reduces a time-dependent parasitic capacity of the PCB between the first vias and/or between the first tracks.
