Abstract: Planar microfluidic devices are laminate structures having a matrix layer at an upper side laminated at an interface to a lower substrate layer. The structure has one or more cavities extending from the upper side to the interface. A membrane is laminated on the upper side of the structure thereby to form a fluid barrier for the cavities. Devices for use as electrochemical sensors further include an electrode at the laminate structure interface below the matrix layer cavity and a well through the substrate layer below the electrode for electrical communication.

Abstract: A condom is provided for enhancing feeling and stimulation on the part of the male by allowing the condom to move, e.g., by a sliding action on the surface of the penis during intercourse. Typically the distal end of the condom is frictionally related to the vagina by weakly bonding the condom to the vagina as by means of a gum-like adhesive agent or by means of a multiplicity of minute fibers bonded on the outside surface of the condom or both. The condom near its open end is held tightly against the base of the penis and, if desired weakly bonded thereto by means of a removable adhesive to form a tight seal.
