Abstract
An igniter comprises at least two conductors in the spaced-apart configuration and an electrically conductive layer bridging the at least two conductors, wherein the conductive layer has an electrical resistance greater than an electrical resistance of the at least two conductors. In one embodiment, the at least two conductors and the electrically conductive layer comprise a conductive ink, which may be the same conductive ink having different dimensions. A supplementary initiator composition may be deposited on or incorporated into the conductive layer. In a process for producing the igniter, the electrically conductive layer and the at least two conductors are printed on a non-electrically conducting substrate. Also disclosed are a method for igniting a combustible composition using the igniter, a method for producing an aerosol drug using the igniter, a method for providing a dose of a drug to a human patient using the igniter, a drug delivery device comprising the igniter and a drug supply unit comprising the igniter.
