1. A vaporizer device for vaporizing a substance containing at least one active and/or aroma material, comprising:

  • a mouthpiece, having at least one fluid inlet and at least one fluid outlet; and

    a heating device, configured to be connected to the mouthpiece, comprising;

    a thermal resistor comprising a metallic foil or a thin sheet in a shape of a dual coil and/or sinuous line, having two ends and dimensions substantially the same as a cross-section of a cigarette or a cigar,wherein interspaces of the shape are configured to allow a flow of fluid therethrough;

    at least one contact tab including a first contact tab and a second contact tab being connected to respective opposed ends of the dual coil and/or sinuous line of the thermal resistor, the first contact tab and the second contact tab not being in direct contact with each other; and

    at least one vaporizer membrane disposed in contact with the thermal resistor and being permeable to the flow of fluid, and which is wetted or can be wetted with the substance containing the at least one active and/or aroma material,wherein the thermal resistor and the at least one vaporizer membrane are arranged orthogonally or at an angle to a direction of the flow of fluid in the mouthpiece.
