Abstract: An aerosol provision system comprising a reservoir for aerosolisable material; a wick configured to receive the aerosolizable material from the reservoir, a vaporizer configured to vaporize the aerosolizable material received in the wick, wherein the aerosol provision system is configured to measure at least one parameter of the wick to determine a status of the wick The parameter may be the moisture content of the wick, at least one physical dimension of the wick, and/or an optical parameter, such as the color of an external surface of the wick, or the reflectivity of an external surface of the wick.

Abstract: The present disclosure provides a non-combustible aerosol provision system and consumables and aerosol generators for non-combustible aerosol provision systems. In various implementations, the non-combustible aerosol provision system comprises a control device that includes an outer housing defining a receiving chamber, a power source and a control component, an aerosol generator coupled to the control device, and an atomizer-free consumable that includes a substrate for engagement with the aerosol generator. The consumable is configured to be removably coupled with one or both of the control device and the aerosol generator. The aerosol generator defines a vaporization chamber and is configured to heat the substrate to generate an aerosol.
