1. A fluid property sensing array for detecting properties of a fluid, the fluid property sensing array comprising
a first sensor including a first electrode assembly and a first sensing layer at least partially coating the first electrode assembly, the first sensor having a first response to a property of the fluid;
a second sensor including a second electrode assembly and a second sensing layer at least partially coating the second electrode assembly, the second sensor having a second response to the property of the fluid; and
a third sensor including a third electrode assembly and a third sensing layer at least partially coating the third electrode assembly, the third sensor having a third response to the property of the fluid;
where the first sensing layer, the second sensing layer, and the third sensing layer are compositionally different, such that the first response, the second response, and the third response to the property of the fluid are different;
where the first sensing layer includes polyimide, where the second sensing layer includes polytetrafluoroethylene, and where the third sensing layer includes a sulfonated tetrafluoroethylene-based fluoropolymer-copolymer.
