wherein the at least one metal film comprises at least one fluid permeable second opening communicating with the at least one fluid permeable first opening,
wherein the at least one metal film forms the one or more heating elements,
wherein the one or more heating elements are arranged so as to delimit the at least one fluid permeable second opening,
wherein the carrier comprises a metal layer,
wherein the metal layer is in contact with the polymer film on a side of the polymer film opposite from the at least one metal film, and
wherein an electrical connection between the at least one metal film and the metal layer is established via one or more contacts.
2. The vaporizer device according to claim 1 ,
wherein the at least one metal film has a passivating coating at least on sections not in contact with the polymer film and/or the one or more heating elements.
3. The vaporizer device according to claim 1 ,
wherein the carrier comprises at least one additional contact for making electrical contact with an electronic component.
4. The vaporizer device according to claim 1 ,
wherein the carrier comprises regions having different thicknesses and/or bending strengths.
5. The vaporizer device according to claim 1 ,
wherein the carrier comprises a liquid interface for a standardized connection with a liquid tank, and
wherein the liquid interface communicates with the at least one fluid permeable first opening and/or the at least one fluid permeable second opening.
6. The vaporizer device according to claim 1 ,
wherein an electrical plug connector part is formed on an edge of the carrier,
wherein the electrical plug connector part is configured for reversible interaction with a corresponding plug connector part of a base part of the inhaler and for supplying the vaporizer device with electrical energy and/or for receiving control signals for the vaporizer device.
7. The vaporizer device according to claim 1 ,
