1. A flexible heater sensor suitable for external association with a fluid bag, comprising:
a conformable substrate on a ply of the fluid bag opposite a printed flexible heater;
a matched function ink set, printed onto at least one substantially planar face of the substrate to form:
at least one conductive layer capable of receiving current flow from at least one power source; and
at least one dielectric layer capable of at least partially insulating and at least partially limiting conductivity of the at least one conductive layer;
wherein the matched ink set is matched to preclude detrimental interactions between the printed inks of each of the at least one conductive and dielectric layers, and to preclude detrimental interactions with the conformable substrate, based on at least one of a compatibility of the substrate, a receptivity the substrate, a conductivity of the inks, a type of printing method performed, a thickness of the printed layers, a chemical reaction between the inks, a curing methodology of the inks, a manner of deposition of the inks, and a surface energy of the substrate; and
wherein the at least one conductive layer and the at least one dielectric layer comprise a sensing circuit that senses at least the temperature of fluid within the fluid bag.
