Abstract: A vaporizer device for vaporizing substances is provided, containing active and/or aroma materials, including a mouthpiece with a fluid inlet and a fluid outlet, and including: a heating device with a thermal resistor being a metallic foil or a thin sheet configured as a dual coil and/or sinuous line with two ends and dimensions of the cross-section of a cigarette or a small cigar, wherein the interspaces of the dual coil and/or sinuous line allow fluid flow therethrough, contact tabs are connected to respective opposed ends of the dual coil and/or sinuous line and are not in direct contact with one another, and at least one permeable and wettable vaporizer membrane in large-area contact with the thermal resistor, wherein the thermal resistor and the at least one vaporizer membrane are arranged orthogonally or at an angle to the direction of the fluids passing through the mouthpiece.

Abstract: A method and device are provided for volatilizing active and/or aroma materials for releasing an inhalable aerosol, wherein a fluid flows through a flow channel in a preferably cylindrical hollow body, wherein the fluid in the flow channel entirely or in part flows through at least one vaporizer membrane in a fluid stream, wherein the at least one vaporizer membrane has been and/or is wetted with a substance containing an active and/or aroma material to be vaporized, and wherein the fluid additionally contains thermal energy and vaporizes the substance on flowing through the vaporizer membrane and supplies the vaporized substance to the fluid stream.
