Abstract
An electronic cigarette includes an atomizer having a coil-less heating element. The coil-less heating element may include a heating section and two leads electrically connected to the heating section. The heating section is made of one or more fiber materials. The two leads may be made of conductive materials that can conduct liquid to the heating section. Alternatively, the heating element may include one or more fiber materials with two conductive sections, and a heating section between the conductive sections. The heating section has a significantly higher electrical resistance than the conductive sections. The different electrical resistances may be achieved by modifying the fiber materials with a material (e.g. metals) having higher electronic conductivity. Different electrical resistances may also be achieved by modifying the shape of the fiber materials to provide the conductive sections with a larger cross-section, and the heating section with a smaller cross-section.
