摘要： An electronic aerosol-generating device includes a housing extending between first and second ends along a longitudinal axis. The second end of the housing defines a cavity for receiving a consumable containing an aerosol generating substrate. The device further includes a heating component comprising a heating element extending along the longitudinal axis within the cavity and configured to penetrate into the aerosol generating substrate when the consumable is inserted into the cavity. The heating element comprises a material having a Curie temperature of less than 500° C. The device also includes an inductor comprising an inductor coil positioned to transfer magnetic energy to the heating element. The inductor is configured to induce eddy currents and/or hysteresis losses in the heating element. The device further includes a power supply operably connected to the inductor and control electronics operably connected to the power supply and configured to control heating of the heating element.

摘要： An aerosol-generating article is provided, including an aerosol-forming substrate and a susceptor configured to heat the aerosol-forming substrate. The susceptor includes a first susceptor material and a second susceptor material having a Curie temperature, the first susceptor material being disposed in intimate physical contact with the second susceptor material. The first susceptor material may also have a Curie temperature, the second Curie temperature being lower than 500° C., and lower than the Curie temperature of the first susceptor material, if the first susceptor material has a Curie temperature. The use of such a multi-material susceptor allows heating to be optimised and the temperature of the susceptor to be controlled to approximate the second Curie temperature without need for direct temperature monitoring.
