Patent number: 12318535Abstract: 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.Type: GrantFiled: October 6, 2021Date of Patent: June 3, 2025Assignee: RAI Strategic Holdings, Inc.Inventors: Stephen Benson Sears, Michael F.

Publication number: 20250151794Abstract: The present invention provides a conductive substrate useful for Joule heating, such as in an electronic smoking article. Particularly, the invention provides a resistive heating element formed of a conductive substrate. The conductive substrate comprises an electrically conductive material and a carbonaceous additive, such as a binder material. The conductive substrate is carbonized in that it is subjected to calcining conditions to effectively reduce the carbonaceous additive to its carbon skeleton. It has been found that such carbonized substrate has surprisingly improved resistance properties in relation a substrate of the same formulation that is not carbonized. The carbonized substrate can include an aerosol precursor material. The formed resistive heating element can be included in an electronic smoking article to simultaneously provide resistive heating and aerosol formation with a single, unitary component.Type: ApplicationFiled: January 14, 2025Publication date: May 15, 2025Inventors: David William Griffith, JR., Yi-Ping Chang, Calvin W. Henderson, Ricky Lee Montgomery, Walter Charles Liebscher, II, Chandra Kumar Banerjee, Paul E. Braxton, Stephen Benson Sears, Kenneth Allen Beard, Timothy Brian Nestor, Balager Ademe, Frederic Philippe Ampolini, Dennis Lee Potter
