1. A cartridge configured to be mounted to a microvaporizer device, the cartridge comprising:
a hollow main body with a recessed wall;
a reservoir inside the hollow main body that is configured to retain a body of liquid;
a flat panel heater adjacent the recessed wall, the flat panel heater being configured to vaporize liquid from the reservoir;
a mouthpiece at one end of the hollow main body, the mouthpiece comprising an opening configured to discharge the vapor generated by the flat panel heater to a user; and
a vapor passage inside the hollow main body that is configured to convey the vapor generated by the flat panel heater to the mouthpiece,
wherein both the reservoir and the vapor passage extend to the same end of the hollow main body as the mouthpiece,
wherein the reservoir is separated from the vapor passage by an interior wall inside the hollow main body,
wherein the recessed wall comprises two fluid openings configured to fluidly connect to fluid passages in the flat panel heater,
wherein a first one of the fluid openings in the recessed wall is fluidly connected to an inlet of the flat panel heater so that the flat panel heater receives fluid through the first fluid opening in the recessed wall, and
wherein a second one of the fluid openings in the recessed wall is fluidly connected to an outlet of the flat panel heater so that fluid vaporized by the flat panel heater is discharged through the second fluid opening of the recessed wall.
