DETECTION OF AEROSOL-FORMING SUBSTRATE IN AN AEROSOL GENERATING DEVICE
First Claim
1. An aerosol generating device, comprising:
- a heater element configured to heat an aerosol-forming substrate;
a power source connected to the heater element; and
a controller connected to the heater element and to the power source,wherein the controller is configured to control the power supplied to the heater element from the power source to maintain the temperature of the heater element at a target temperature, and is configured to compare a measure of power supplied to the heater element or energy supplied to the heater element from the power source to a threshold measure of power or energy to detect the presence of the aerosol-forming substrate close to the heater element or a material property of the aerosol-forming substrate close to the heater element.

9. A method for detecting the presence of an aerosol-forming substrate close to a heater element or a material property of the aerosol-forming substrate in an aerosol generating device, the aerosol generating device comprising the heater element configured to heat the aerosol-forming substrate and a power source connected to the heater element, the method comprising:
-
controlling the power supplied to the heater element from the power source to maintain the temperature of the heater element at a target temperature; comparing a measure of power supplied to the heater element or energy supplied to the heater element from the power source to a threshold measure of power or energy; and determining the presence of the aerosol-forming substrate close to the heater element or a material property of the aerosol-forming substrate close to the heater element based on a result of the step of comparing. - View Dependent Claims (10, 11, 12, 13)
