Fluidic actuator comprising deformable seal arrangement and long storability
A fluidic actuator includes a basic arrangement having at least one cavity formed therein, an activatable substance within the cavity, and a deformable seal arrangement. The activatable substance, exemplarily an electrolyte, may be converted, at least partly, by suitable activation and thus cause a change in pressure in the cavity. The deformable seal arrangement serves for sealing the cavity. The seal arrangement includes an element containing paraffin and may be deformed when activating the activatable substance due to the change in pressure of the activatable substance. A corresponding method of manufacturing includes the following steps: providing the basic arrangement; forming a cavity, which is open on at least one side, in the basic arrangement; introducing the activatable substance into the cavity; and sealing the cavity using the deformable seal arrangement which includes an element containing paraffin.
