FLAT PRESSURE SENSOR UNIT

Abstract

The invention relates to a flat pressure sensor unit, in particular a pressure sensor sheet (3), comprising first conductor paths (310) and second conductor paths (32) and a central layer (33) arranged between the first and the second conductor paths (310, 320). The first and second conductor paths (310, 320) cross one another, spaced apart by the central layer (33), whereby cross-over points (30) are formed in order to detect, as sensors, a spacing change between the first and second conductor paths (310, 320) generated by an external application of pressure. The conductor paths (310, 320) are sewn onto at least one material layer (31, 32). First and second connecting paths (390, 391) are provided, leading away from the first and second conductor paths (310, 320), extending towards at least one electronics unit (380, 381) and ending at the at least one electronics unit (380, 381). The first and second conductor paths (390, 391) are sewn on the at least one material layer (31, 32). The flat pressure sensor unit can be easily and economically produced and allows for flexible design both in the selection of the material layers (31, 32) and in the arrangement of the conducting and connecting paths (310, 320, 390, 391).
