Fluidic actuator comprising deformable seal arrangement and long storability

A method for manufacturing a fluidic actuator, comprising:

• providing a basic arrangement;
• forming a cavity, open on at least one side, in the basic arrangement;
• introducing an activatable substance into the cavity, configured to be converted at least partly to one or several different substances by suitable activation or, when activated, changes its state of aggregation at least partly, thereby causing a change in pressure in the cavity;
• and
• sealing the cavity using a deformable seal membrane by mechanically affixing the deformable seal membrane to the basic arrangement to prevent an escape of the activatable substance from the cavity;
• wherein
• the deformable seal member includes a film including a paraffin portion or an expandable film including a paraffin layer on at least one main surface and may be deformed when activating the activatable substance due to the change in pressure;
• and
• the method further includes a step of mechanically affixing the film or the expandable film to the basic arrangement.
