An atomiser for an electronic cigarette comprising a first and second leads between which are electrically connected a plurality of organic or inorganic conductive fibres, wherein the conductive fibres have a higher electrical resistance than the leads. The conductive fibres may comprise carbon, SiO2, TiOÂ2, ZrO2, Al2CO3, Li4Ti5O12, LiN, Fe-Cr-Al, NiCr, ceramic, polyaniline aramid or organometalics. Portions of the conductive fibres may be coated with resistivity reducing conductive materials, such as metals, carbon or SnCl2. The leads and fibres may be mounted upon a printed circuit board, through which a hole aligning with the fibres is located. The electronic cigarette in which the atomiser is installed may further include a battery and a liquid supply reservoir from which fluid is supplied to the atomiser, such supply being achieved optionally via a wicking element. The first and second leads may also be porous and allow liquid to be supplied to the heating element of the atomiser, eliminating the requirement for a separate wick. The electronic cigarette may further comprise a sensor connected to the battery for sensing inhalation.
