| abstract |
An aerosol provision system (1) comprising a reservoir (31) for aerosolisable material; a wick (42) configured to receive the aerosolisable material from the reservoir (31), a vaporiser (40) configured to vaporise the aerosolisable material received in the wick (42), wherein the aerosol provision system (1) is configured to measure at least one parameter of the wick (42) to determine a status of the wick (42). The parameter may be the moisture content of the wick (42), at least one physical dimension of the wick (42), and/or an optical parameter, such as the colour of an external surface of the wick (42), or the reflectivity of an external surface of the wick (42). |
