Abstract

The present disclosure relates to atomizers for an aerosol delivery device such as a smoking article. The atomizer may include a liquid transport element and a wire extending along at least a portion of a longitudinal length thereof. The wire may define contact portions configured to engage heater terminals and a heating portion configured to produce heat. The heating portion may include a variable coil spacing. In other atomizers, the wire may extend at least partially through the liquid transport element proximate the contact portions. Related inputs, cartridges, aerosol production assemblies, and methods of forming atomizers are also provided.
