Abstract: An aerosol provision system for generating an aerosol from a source liquid, the aerosol provision system including: a reservoir of source liquid; a planar vaporizer comprising a planar heating element, wherein the vaporizer is configured to draw source liquid from the reservoir to the vicinity of a vaporizing surface of the vaporizer through capillary action; and an induction heater coil operable to induce current flow in the heating element to inductively heat the heating element and so vaporize a portion of the source liquid in the vicinity of the vaporizing surface of the vaporizer. In some example the vaporizer further comprises a porous wadding/wicking material, e.g. an electrically non-conducting fibrous material at least partially surrounding the planar heating element (susceptor) and in contact with source liquid from the reservoir to provide, or at least contribute to, the function of drawing source liquid from the reservoir to the vicinity of the vaporizing surface of the vaporizer. In some examples the planar heating element (susceptor) may itself include a porous material so as to provide, or at least contribute to, the function of drawing source liquid from the reservoir to the vicinity of the vaporizing surface of the vaporizer.

Abstract: An aerosol provision system comprises a heating element for generating an aerosol from a source liquid and control circuitry for controlling a supply of electrical power from a power supply to the heating element. The control circuitry is configured to measure an indication of a derivative of an electrical characteristic of the heating element with respect to time. Based on the measured time derivative, the control circuitry is configured to determine whether or not a fault condition has arisen for the electronic aerosol provision system. The overall change in the electrical characteristic for the heating element caused by the localized heating may be small and so difficult to reliably identify, but the rate at which the change occurs can be expected to be relatively high, such that the time derivative of the local characteristic is a more reliable indicator of occurrence of the fault condition.
