1. An aerosol-generating system, comprising:
an aerosol-generating device comprising a power source; and
a cartridge removably coupled to the aerosol-generating device, the cartridge comprising:
a liquid storage portion comprising a housing having an open end and containing a liquid aerosol-forming substrate,
a substantially flat heater assembly fixed to the open end of the housing and comprising an electrical heating element configured to heat the liquid aerosol-forming substrate to form an aerosol, the electrical heating element being both substantially flat and arranged in a curved manner,
a capillary material disposed in contact with the electrical heating element and comprising a ceramic or a ceramic-based material, the capillary material being configured to convey the liquid aerosol-forming substrate to the electrical heating element, and
a plurality of air inlets and an air outlet,
wherein the liquid storage portion is disposed at a first side of the heater assembly and an airflow channel is disposed at a second side of the heater assembly, the airflow channel defining an airflow path over the heater assembly and configured to convey the aerosol, and
wherein the power source of the aerosol-generating device is configured to supply power to the substantially flat heater assembly.
