Abstract: A heater having a multiple-layer ceramic substrate and a method for fabricating the heater are provided. The heater consists-of a plurality of ceramic layers which are laminated to form a single ceramic substrate. A plurality of resistive heating elements are deposited onto the multiple-layer ceramic substrate, which are connectable to a power source via conductive elements which extend through the substrate to the resistive heating elements. The heater may also include a terminal that allows for convenient electrical and mechanical interfacing to a smoking article.

Abstract: A flavor source to be used as a thermally releasable flavorant for smoking articles that do not combust tobacco. The flavor source includes tobacco particles, an aerosol precursor that forms an aerosol upon exposure to heat, and a gelling agent that imparts sufficient structural framework for rigidity to the flavor source. The material is mixed, extruded through a die, and cut into the shape of a one-piece flavor source. The flavor source is loaded into a chamber for inclusion in a smoking article as a flavor generator.
