    Abstract: A reversible bonded microfluidic structure comprises an overhanging cap or gasket structure atop a continuous microfluidic channel wall. An overhanging gasket structure may reduce stress concentrations at the edge of the channel wall and can permit improved reversible adhesion of the channel wall and adjacent dry adhesive fibers. In one example, reversible adhesion of the overhanging channel wall gasket and adjacent dry adhesive fibers may approach 1 MPa in axial loading. An overhanging gasket structure of the microfluidic channel wall may comprise a single “fiber” that is continuous around the perimeter of the desired microfluidic channel shape, and may define a self-sealing gasket which will contain fluid. The overhanging gasket structure may be surrounded by further overhanging or undercut dry adhesive fibers to enhance the adhesion and help make the rest of the surface more tolerant to defects and surface roughness.

    Abstract: The invention is directed to carbon nanostructure composite systems which may be useful for various applications, including as dry adhesives, electronics and display technologies, or in a wide variety of other areas where organized nanostructures may be formed and integrated into a flexible substrate. The present invention provides systems and methods wherein organized nanotube structures or other nanostructures are embedded within polymers or other flexible materials to provide a flexible skin-like material, with the properties and characteristics of the nanotubes or other nanostructures exploited for use in various applications. In one aspect, the invention is directed to a carbon nanotube/polymer composite material having a plurality of carbon nanotubes formed into a predetermined architecture, with each of the plurality of nanotubes having a desired width and length. The architecture of the plurality of nanotubes defines at least one orientation for a plurality of nanotubes, and also defines the approximate spacing between nanotubes and/or groups of nanotubes. The carbon nanotube architecture is at least partially embedded with a polymer matrix in a manner that the architecture is stabilized in the predetermined architecture. The polymer matrix may also be formed to have a desired predetermined thickness.

    Abstract: A microstructure made of flexible material includes a plurality of projections extending from a common substrate. A distal end of each projection includes a resilient flap. All lateral dimensions of each of the projections increase monotonically with increased distance from a surface defined by distal ends of the flaps when the flaps are unbent. Each of the projections extends from the common substrate in a general direction that is locally substantially perpendicular to the surface defined by the ends of the flaps. When a shear force is applied to each of the flaps by relative motion between the flap and a cooperating surface in contact with the flap, the flap bends so as to increase the area of contact of that flap with the cooperating surface, affecting adhesion between the microstructure and the cooperating surface.
