Abstract
The present disclosure relates to gripping surfaces and devices comprising the same, wherein the gripping surface comprises a shape tunable surface microstructure, wherein the height, width and spatial periodicity of the microstructures corresponds to an integer multiple of Schallamach wave amplitudes and wavelengths of a target surface, wherein the device microstructures and induced Schallamach waves are entrained by applying strain to the device.
Claims15
A device having a gripping surface comprising a first array of deformable microstructure features, wherein the gripping surface is disposed on a substrate, the substrate having a thickness from 20 microns to 1000 microns, wherein one or more features of the first array of deformable microstructure features includes a height from 10 microns to 100 microns, a width from 10 microns to 100 microns, and a pitch from 50 microns to 200 microns, wherein the first array of deformable microstructure features are configured to contact a target surface and wherein a shear stress applied to the deformable microstructure features causes the features to deform such that the deformation corresponds to an integer multiple of Schallamach wave amplitude and wavelength of the target surface and wherein the deformable microstructure features and Schallamach waves are entrained.
