    摘要: A base layer, which is preferably flexible, has first conductor tracks, a first insulation layer, fine structures with first electrodes, second conductor tracks and second electrodes, and finally a second insulation layer applied to it in succession. The first electrodes are connected, via plated-through holes, to associated first conductor tracks. Changes, caused by lines in the skin of a finger pad, in the stray capacitance between adjacent first and second electrodes are evaluated for recording fingerprints.
