Abstract
An electric heating and capacitive sensing arrangement that includes: an electrically conductive heating track arranged on a surface of a planar substrate, the electrically conductive track being connectable to a current source so that during a heating operation a current flows through the electrically conductive track. The electrically conductive track is connectable to a capacitive sensing circuit so that during a sensing operation a capacitive sensing signal is applied to the electrically conductive track. The electrically conductive track has at least a first and a second heating track section extending at a distance along each other on the substrate, whereby a gap is formed between the first and the second heating track section. The heating and sensing arrangement further includes a layer of electrically conductive material arranged on the surface of the substrate in the gap between the first and the second heating track section.
