The present disclosure provides an aerosol delivery device and a liquid delivery and atomization assembly for use with an aerosol delivery device. In one implementation, the liquid delivery and atomization assembly may comprise a liquid composition, an atomization assembly, and a liquid transport element configured to transport at least a portion of the liquid composition to the atomization assembly. The atomization assembly may comprise a piezoelectric component that includes an interdigital transducer configured to generate surface acoustic waves that vaporize the portion of the liquid composition to generate an aerosol. The liquid transport element may comprise one or more of a fibrous material that includes fibers having a multi-lobal cross-section, a perforated disk, or a combination thereof. The perforated disk may include a plurality of openings and a plurality of microchannels that extend from a periphery of the disk to the plurality of openings.

An aerosol delivery device is provided that comprises a control body and an aerosol source member. The aerosol delivery device includes a resonant transformer comprising a resonant transmitter and a resonant receiver. The aerosol source member includes an inhalable substance medium at least a portion of which is positioned proximate the resonant transmitter. The resonant transmitter is configured to generate an oscillating magnetic field and induce an alternating voltage in the resonant receiver when exposed to the oscillating magnetic field, such that the alternating voltage causes the resonant receiver to generate heat and thereby vaporize components of the inhalable substance medium to produce an aerosol. In some implementations, the resonant receiver comprises part of the control body. In other implementations, the resonant receiver comprises part of the aerosol source member.

Aerosol delivery device having a resonant transmitter

A method of modifying the moisture level of (e.g., dehydrating) a tobacco plant or portion thereof, a tobacco-derived material, a tobacco product, or a tobacco additive is provided herein. The methods of dehydration disclosed herein can provide various benefits relative to traditional drying techniques, including providing retention of various beneficial components present in green tobacco (e.g., organoleptic compounds and proteins). Smoking articles and other tobacco products including such dehydrated tobacco materials are also provided.

Dehydration of tobacco and tobacco-derived materials

The present disclosure relates to a microfluidic vaporizer, an aerosol delivery device that may include such vaporizer, and methods for forming an aerosol. A microfluidic vaporizer can comprise a substrate that defines: a reservoir configured to hold a liquid; a heater adapted to vaporize the liquid; and a capillary channel configured for movement of the liquid from the reservoir to the heater. An aerosol delivery device can comprise a shell and a microfluidic vaporizer. The microfluidic vaporizer and aerosol delivery device can be used for forming aerosols with precise and reproducible compositions.

The disclosure provides for oral compositions that exhibit desired properties associated with moist products while incorporating a relatively low water content. Such compositions may include at least one releasable material, at least one filler/carrier component, and at least one water substitute, such as a polyol. The water substituted may be present in an amount of about 25% by weight or greater based on the total weight of the oral composition, and the compositions and products formed therewith can exhibit a relatively low water activity, such as in the range of about 0.85 or less. The present disclosure further provides methods of forming an oral composition with a mouthfeel corresponding to a moist product while having a relatively low water activity.
