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 continuously extending along a longitudinal length thereof. The wire may define end portions, contact portions, and a heating portion. The wire may be continuously wound about the liquid transport element such that each of the portions of the wire defines coils. A related input, cartridge, and method of forming atomizers also provided.
