Abstract:
1. A fluid coupler comprising plural film layers disposed on the substrate top surface of an included substrate, the plural film layers disposed with respect to one another to define a top film layer and a bottom film layer, the top film layer defining a film layer top surface and the bottom film layer defining a film layer bottom surface, each film layer having two opposing film layer sides with a corresponding film layer thickness or spacing therebetween, each film layer further having one or more regions that are devoid of film material, each film layer thus forming one or more cavities with corresponding cavity openings on both of its film layer sides, each film layer having one or more of its cavities disposed to provide fluid coupling with its respective adjacent film layer or with both of its respective adjacent film layers, as the case may be, the plural film layers disposed to form at least one film layer traverse channel coupling at least one cavity opening in the film layer top surface with at least one cavity opening in the film layer bottom surface, the plural film layers comprising any of structural bonding tape, adhesive films and double-sided tape.
