Abstract: A sensor comprises a plurality of sensor elements arranged in an array. Each sensor element is memristive and has an electrical resistance characteristic related to exposure to a species to be sensed. The sensor elements are arranged to be connectable such that at least one sensor element is connected in parallel with at least one other sensor element. By using appropriate connections, the array of sensor elements can be read.

Abstract: A sensor kit for detecting an analyte. The sensor kit includes x indicator substances having a specific spectral response to the analyte, whereby 1?x?200. The sensor kit includes a substrate, which is to be illuminated on a first side and includes at least one indicator substance region arranged adjacent to a second side. Each indicator substance region is arranged for carrying one indicator substance and the substrate includes at least one indicator substance region for each indicator substance. A filter element is integrated with the substrate. The filter element includes at least one of each of n different filters, whereby 2?n?100. The filter element is arranged such that light firstly passes there through and thereafter through the indicator substance region(s). At least one of each of at least two different filters provides at least one indicator substance region with light when the substrate is illuminated.
