  • Patent number: 11690963
    Abstract: An electronic device for producing an aerosol for inhalation by a person includes a mouthpiece, a liquid container, and a mesh assembly having a mesh material and a piezoelectric material. The mesh material is in contact with a liquid of the container. The mesh material is configured to vibrate when the piezoelectric material is actuated, whereby the aerosol is produced. The aerosol may be inhaled through the mouthpiece. The device also includes circuitry and a power supply for actuating the mesh assembly. The mouthpiece, the container, and the mesh assembly are located in-line along a longitudinal axis of the device between opposite longitudinal ends of the device, with the mesh assembly extending between and separating the mouthpiece and the container. The mesh material has a rigidity that is sufficient to prevent oscillations of varying amplitudes during actuation of the piezoelectric material of the mesh assembly for consistently producing the aerosol.

  • Patent number: 11602175
    Abstract: 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.
