| titleOfInvention | Aerosol-generating device having capacitance based power control |
| abstract | An aerosol-generating system comprising: an aerosol-generating article (140) comprising an aerosol-forming substrate (142), the aerosol-forming substrate (142) being a dielectric material; an aerosol-generating device (110); and a first electrode (128) and a second electrode (130). The aerosol-generating device (110) comprises: a power supply (126); at least one heater (120); and a cavity (114) for receiving the aerosol-generating article (140). The aerosol-generating device (110) further comprises a controller (124) configured to control a supply of power from the power supply (126) to the at least one heater (120) for heating the aerosol-forming substrate (142) when the aerosol-generating article (140) is received within the cavity (114). The second electrode (130) is spaced apart from the first electrode (128) so that at least a portion of the aerosol-forming substrate (142) is received between the first electrode (128) and the second electrode (130) when the aerosol- generating article (140) is received within the cavity (114). The first electrode (128), the portion of the aerosol-forming substrate and the second electrode (130) form a capacitor when the aerosol- generating article (140) is received within the cavity. The controller (124) of the aerosol-generating device (110) is further configured to: measure the capacitance of the capacitor via the first and second electrodes (128, 130) when the aerosol-generating article (110) is received within the cavity (114); supply power from the power supply (126) to the at least one heater (120) in a first power profile when the measured capacitance is within a predetermined first range; and supply power from the power supply (126) to the at least one heater (120) in a second power profile, different to the first power profile, when the measured capacitance is within a predetermined second range. |
