1. An aerosol-generation apparatus comprising a heater and a fluid-transfer article, said fluid-transfer article having a first region, and a second region comprising an activation surface, the first region being for holding an aerosol precursor and for transferring said aerosol precursor to the activation surface, said activation surface being disposed and configured for thermal interaction with a heating surface of said heater;
said second region comprising at least one discontinuity in said activation surface to form a corresponding at least one channel between said second region and said heating surface and being configured such that, when the fluid transfer article is arranged with respect to said heating surface of the heater for thermal interaction therebetween, the or each channel opposes and opens towards said heating surface, and provides an air-flow pathway across said heating surface;
wherein the heater comprises a substrate defining said heating surface, and at least one heating element formed on a part of said heating surface; and
wherein said at least one channel opposes a further part of said heating surface other than said part of said heating surface on which the at least one heating element is formed, such that the at least one heating element is not aligned with any of the or each channel, but is aligned with a part or parts of the activation surface that projects towards the heater.
