Patent ID: 10912336

Abstract:
An aerosol-generating system is provided, including an aerosol-generating article including an aerosol-generating substrate, a first electrode, and a dielectric material including a porous substrate material and a liquid sorbed into the porous substrate material; and an aerosol-generating device including a power supply; at least one heater; a cavity to receive the article; a first electrical contact contacting the first electrode when the article is received within the cavity; a controller; and a second electrode, such that when the article is received, the dielectric is disposed between the first and second electrodes to form a capacitor, the controller being configured to control a supply of power from the power supply to the heater for heating the aerosol-generating substrate and the dielectric, and to the capacitor, and to measure a capacitance of the capacitor and to terminate the supply of power to the heater when a measured capacitance exceeds a predetermined threshold.
