摘要：
A heater element (41) includes a first polymer film (42) having an electricallyconductive circuit. The circuit may include conductive ink (44), a second polymerfilm (43), and/or resistive or conductive overmolded material (57). The firstpolymer film (42) is molded into at least one surface of a molded object (46, 50,51, 150, 250, 350). The molded object may be a humidifier (51) or a component (50,150, 250, 350) of a humidifier. A method of manufacturing an in-mold heater element(41) includes providing an electrically conductive circuit on a surface of afirst polymer film (42)； placing the first polymer film including the electricallyconductive circuit in a mold such that the non-printed surface of the polymerfilm is adjacent the mold； and insert molding resin (46) to form a predeterminedmolded shape such that the first polymer film (42) is incorporated within at leastone surface of the molded shape. A method of humidifying a flow of pressurizedbreathable gas includes passing the flow of pressurized breathable gas overa supply of water (W) contained in a tub (50, 150, 250, 350). The tub is formed ofmolded resin and a heater comprising a polymer film (42) having a layer of electricallyconductive ink (44), a stamped resistive or conductive film (43), and/or resistiveor conductive overmolded material (57) on a first surface is molded at least partiallywithin the resin.
