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.

Systems and methods for using a non-stick conductive material to automate tool touch-off in an additive manufacturing process are provided. A substrate comprises a first conductive layer, an intermediate binder layer, and a second non-stick conductive layer. The non-stick conductive layer may comprise perfluoroalkoxy alkanes and carbon nanotubes. An electrical connection may be made between the first conductive layer and the second non-stick conductive layer. When used with an additive manufacturing device, when the nozzle of the device contacts the substrate, a circuit may close resulting in a detectable voltage drop. When the voltage drop is detected, a reference point for the additive manufacturing device may be set.

A phosphor-containing identification substance of the present invention includes a substrate and a phosphor-containing silicone thin layer. The whole or part of the surface of the substrate is covered with the phosphor-containing silicone thin layer. The phosphor has identification properties that the phosphor emits light when irradiated with ultraviolet rays or black light, and does not emit light when irradiated with visible rays.
