Sensor arrangement with improved spatial and temporal resolution
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 sensor arrays comprising;
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, the sensor element being set up such that the sensor element influences electric current flow between a respective row line and a respective column line through the respective at least one coupling device;
an accumulative current flow detector, which is 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 and serves for detecting a respective accumulative current flow from the individual electric current flows provided by the sensor arrays of the respective lines; and
a decoding device, which is coupled to the row lines and the column lines and is set up such that at least one sensor element at which a sensor signal is present can be determined from at least a portion of the accumulative electric current flows which can be fed to the decoding device via the row lines and the column lines, wherein the decoding device is set up such that a plurality of accumulative current flows which satisfy a predetermined first selection criterion can be determined from the detected accumulative current flows, that from the accumulative current flows determined at least one accumulative current flow can be selected as an accumulative current flow which represents a sensor signal and which satisfies a predetermined second selection criterion, and that the sensor element at which a sensor signal is present can be determined from the selected accumulative current flow.

Abstract
Sensor arrangement having sensor arrays arranged in crossover regions of row and column lines, each of the sensor arrays having a coupler and a sensor element, which influences current flow between a row and column line through the coupler, an accumulative current flow detector that detects accumulative current flow from individual electric current flows provided by the sensor arrays, and a decoder that determines a sensor element at which a sensor signal is present from the accumulative electric current flows. Accumulative current flows which satisfy a predetermined first criterion can be determined from the detected accumulative current flows, and from the accumulative current flows determined an accumulative current flow can be selected as an accumulative current flow which represents a sensor signal and which satisfies a predetermined second criterion, and the sensor element at which a sensor signal is present can be determined from the selected accumulative current flow.
