Abstract
An apparatus is provided for enabling smokable material to be heated to volatize at least one component of the smokable material. In one example, the apparatus has a capacitive sensor arranged to sense a change in capacitance when an article of smokable material is associated with a housing of the apparatus in use. In another example, the apparatus has a resistive sensor arranged to provide a measure of electrical resistance when an article of smokable material is associated with a housing of the apparatus in use. A combination of capacitive and resistive sensing may be used in some examples. In another example, a sensor makes use of at least two different sensing techniques. There is also provided an article of smokable material having a non-metallic electrically conductive region for detection by a sensor of an apparatus arranged to cause heating of the smokable material.
