摘要： Described herein is a microstructure having a substrate and a plurality of nano-fibers attached to the substrate. Each nano-fiber moves between the first and second states without an external mechanical load being applied to the nano-fibers. Each nano-fiber is configured to move between a first state and a second state in response to applied electricity, magnetism, chemical solution, heat, or light. Each nano-fiber is straight in the first state and curved in the second state, and when the nano-fibers are in the second state and in contact with a contact surface, the nano-fibers adhere to the contact surface.

摘要： A fabricated nano- structure includes a substrate, a supporting stalk, a node, and at least two spatular plate portions. The supporting stalk has a first end opposite a second end. The first end of the supporting stalk is connected to the substrate. The supporting stalk has a diameter range of about 50 nanometers to about 2 microns. A node is disposed at the second end of the supporting stalk. At least two spatular plate portions are connected to the node. The at least two spatular plate portions have planar geometries and are radially distributed about the node. The at least two spatular plate portions has a ratio of a maximum plate thickness to a maximum plate length of at most about 1:20. The maximum plate length is measured along a line from a boundary of the spatular plate portion to a centroid of the node. The maximum plate length is at least about 100 nanometers. The at least two spatular plate portion adhere to a contact surface using intermolecular forces when the spatular plate portions are in contact with the contact surface.

摘要： Described herein are fabricated microstructures to adhere in shear to a contact surface. A fabricated microstructure comprises a substrate and a plurality of nano-fibers attached to the substrate. The nano-fibers have an elasticity modulus E, an interfacial energy per unit length of contact w, a length L, a radius R, and are oriented at an angle θ o relative to the substrate. The length L of the nano-fibers is greater than 0.627θ o R 2 (E/w) 1/2 with θ o in radians. Also described herein is a method of forming a fabricated microstructure to adhere in shear to a contact surface and a method of adhering in shear a fabricated microstructure to a contact surface.
