Apparatus, system and method of providing a fluid bag heater

A flexible heater formed on at least one conformable substrate of a medical fluid bag, comprising:

• a matched function ink set, printed onto at least one substantially planar face of the at least one substrate to form at least:
• at least one conductive layer capable of receiving current flow from at least one power source, having a cartridge physically and electrically associated with the at least one conductive layer;
• at least one resistive layer electrically associated with the at least one conductive layer and comprising a plurality of heating elements capable of generating heat upon receipt of the current flow;
• and
• at least one dielectric layer capable of at least partially insulating the at least one resistive layer;
• wherein the matched ink set is matched to preclude detrimental interactions between the printed inks of each of the at least one conductive, resistive and dielectric layers, and to preclude detrimental interactions with the at least one conformable substrate.
