Sensor arrangement
First Claim
1. A sensor arrangement comprising:
- a plurality of row lines arranged in a first direction;
a plurality of column lines arranged in at least a second direction;
a plurality of sensor arrays arranged in crossover regions of the row lines and the column lines, each of the plurality of sensor arrays having;
at least one coupling device for electrically coupling a respective row line to a respective column line; and
a sensor element assigned to the at least one coupling device, wherein the sensor element influences electric current flow through the at least one assigned coupling device;
a detector electrically coupled to a respective end section of at least a portion of the row lines and of at least a portion of the column lines, the detector detecting a respective accumulative current flow from the individual electrical current flows provided by the sensor arrays of the respective lines; and
a decoding device coupled to the row lines and the column lines, the decoding device evaluating at least a portion of the accumulative electric current flows fed to the decoding device via the row lines and the column lines to determine at which of the sensor elements a sensor signal is present.

Abstract
Sensor arrangement having row and column lines arranged in first and second directions, respectively, sensor arrays arranged in crossover regions of the row and column lines, a detector, and a decoding device. The sensor arrays have a coupling device for electrically coupling respective row and column lines, and a sensor element to influence electric current flow through the coupling device. The detector is electrically coupled to a respective end section of at least a portion of the row and column lines, and detects a respective accumulative current flow from the individual electrical current flows provided by the sensor arrays of the respective lines. The decoding device is coupled to the row and column lines, and evaluates at least a portion of the accumulative electric current flows fed to the decoding device via the row and column lines to determine at which of the sensor elements a sensor signal is present.
