Abstract:
The present invention provides a shear gripper device using fibrillar, gecko-inspired adhesives that have the characteristics of being non-tacky in its default state and requiring no normal force to grip a surface. The adhesion is turned “on” by the applied shear load, and “off as the shear load is removed. The shear adhesive gripper is able to grasp large, deformable or delicate objects using a delicate touch.

Claim (Index 1):
A shear gripper device, comprising:\n (a) a first gripper and an opposing second gripper, wherein the first and second gripper are spaced from each other to allow the positioning of an object in between the first and second gripper; (b) a mechanism to manipulate the relative position between the first gripper and the second gripper relative to the object, wherein both the first and second gripper comprise: (i) a backing structure with a layer-facing surface; and (ii) a layer of directional dry adhesives having a backing-facing surface and an object-facing surface, wherein the object-facing surface distinguishes a plurality of stalks, wherein the backing-facing surface rests on the layer-facing surface of the backing structure, and wherein the layer of directional dry adhesives of the first gripper opposes and faces the layer of directional dry adhesives of the second gripper, wherein when the mechanism causes the first and second gripper to close in onto the object, the compliance of the first and second gripper is designed to conform the first and the second gripper to the surface of the object, whereby each of the layers of directional dry adhesives sits in between their backing structures and the object, wherein the compliance of the plurality of stalks of the first and second gripper allow them to deform when in contact with the object, and wherein the shear forces applied by the plurality of stalks of the first and second gripper onto the surface of the object causes the shear gripper device to support the weight of the object while the object is being manipulated.
