Abstract: Producing a foil element, comprises: providing an elastically deformable first layer (101) with a first surface, applying first spaces from a curable polymer material in a first arrangement on the first surface, providing an elastically deformable second layer (103) with a second surface, joining the second surface to the first spaces on their ends facing away from the first surface, moving apart the first and second layer such that the first and second surface has a predetermined spacing from each other and the first spacers connect the first and second surface and curing the first spacers. Producing a foil element, comprises: providing an elastically deformable first layer (101) with a first surface, applying first spaces from a curable polymer material in a first arrangement on the first surface, providing an elastically deformable second layer (103) with a second surface, joining the second surface to the first spaces on their ends facing away from the first surface, moving apart the first and second layer such that the first and second surface has a predetermined spacing from each other and the first spacers connect the first and second surface and curing the first spacers; or providing an elastically deformable first layer with a first surface, applying individual second spacers (102) from a curable polymer material in a second arrangement on the first surface, providing an elastically deformable second layer with a second surface, applying individual third spacers (104) from a curable polymer material in a third arrangement, which is mirror-symmetrical to the second arrangement on the second surface, aligning the first and second layer such that the arrangements of the second and third spacers applied to the first and to the second surface are congruently located opposite one another, joining the second and third spacers in each case located congruently opposite one another at their respective free ends, moving apart the first and second layer such that the first and the second surface has a predetermined spacing from each other and the spaces connect the first and second surface and curing the spacers, where the polymer material of the first spacers is elastically deformable after the curing and the first spacers space apart the first and the second surface at a spacing in a mechanically unloaded state. The polymer material of the spacers is elastically deformable after the curing and the spacers space apart the first and the second surface at the spacing in a mechanically unloaded state. An independent claim is also included for a foil element comprising an elastically deformable first layer with a first surface, an elastically deformable second layer with a second surface, where the first and the second surfaces face one another, and are spaced from one another and connected to each other through individually arranged elastically deformable spacers formed between the first and second surface, and intermediate spaces are formed between the first and the second surface.
