Abstract
A smoking article includes a housing that has a mouthpiece and that is configured to receive an aerosol generating substrate. The smoking article also includes a sensor that is positioned at, for example, the mouthpiece and that is configured to detect an oronasal molecule of a prospective smoker of the article. The oronasal molecule can be a molecule that would be expected to be present in breath or saliva of a smoker but not in the breath or saliva of a non-smoker. The sensor is positioned to detect an amount or concentration of a molecule in the smoker's breath or saliva. The smoking article can use data transduced by the sensor to control delivery of an aerosol from the smoking article, such as to prevent delivery of the aerosol.
Claims14
A smoking article comprising:
- a housing having a mouthpiece and configured to receive an aerosol generating substrate;
- a sensor positioned at or in proximity to the mouthpiece and configured to detect an oronasal molecule of a prospective smoker of the article;
- and
- control electronics configured to control delivery of an aerosol generated from the aerosol generating substrate through the mouthpiece, wherein the control electronics are operably coupled to the sensor and are configured control the delivery of the amount of the aerosol based on data received from the sensor.
