Abstract
The sensor device is provided for sensing biometric characteristics, in particular finger minutiae, with a biometric sensor chip. The sensor chip is fastened on a flexible printed circuit board that has a highly flexible substrate layer and conductor tracks applied to the substrate layer. The conductor tracks are in electrical contact with the sensor chip and are led to a terminal region of the flexible printed circuit board. The sensing area of the sensor chip is accessible through an opening in the flexible circuit board and the opening is at least partially surrounded by a grounding frame.
