Abstract (en)
[origin: EP3711603A1] An aerosol delivery system (12,18) has a fluid transfer article (34) with a first region (34a) for holding an aerosol precursor and a second region (34b) to which the aerosol precursor is transferred from the first region. The second region includes a multiplicity of fibres which extend from the first region to an end of the fluid-transfer article wherein some of said multiplicity of fibres terminate at, a heating surface of said heater, and others of said fibres terminate short from said heating surface, thereby to define at least one channel (41) among said fibres, said at least one channel forming an air-flow pathway along said heating surface. The aerosol precursor passes along the fibres and interacts thermally with the heater to form an aerosol from said aerosol precursor. The first region may be formed from a porous polymer material. When the user sucks or inhales through the aerosol delivery system, air-flows through the air-flow pathway along and the heating surface, so that aerosol passes from the heater and/or the ends of the fibres to the user in the air-flow.
