Sheet with integrated sensor system

The present invention relates to a flexible sheet made of a polymer material, preferably a plastics-material sheet provided with a grain structure or embossing, which has functional surface-area regions designed in the form of a switching, sensor or operating element such that the sheet is of multi-layered design at least in the region of the functional surface-area regions, wherein at least one layer made of conductive polymer material is arranged in the functional surface-area regions, wherein the layer made of conductive material is spaced apart, on the rear side, from the visible surface of the sheet and is connected to an electronic control and regulating device, which detects changes in electrical properties of the sheet in the functional surface-area regions and converts these into actuating, switching or control signals. 种由聚合物材料制成的挠性片材、优选设有颗粒结构或隆起的塑料材料片材，该片材具有功能性表面区域，这些功能性表面区域是以开关元件、传感器元件或操作元件的形式设计的，使得至少在这些功能性表面区域的范围中，该片材具有多层式设计，其中，至少个由导电聚合物材料制成的层被安排在这些功能性表面区域中，其中该由导电材料制成的层位于后侧上、与该片材的可见表面间隔开、并且连接至电子的控
