Abstract

The invention provides novel devices, systems, designs, materials and fabrication methods that enable high-load capacity, easy release, and suitable for extended/repeated use in a variety of applications.

First claim

What is claimed is:

1. A releasable surface-adhesive device, comprising:
an adhesive pad, comprising:
a planar backing layer;
a planar layer of an elastic material having an adhesive surface on at least one side for adhering to a target surface, wherein a side of the planar layer of the elastic material opposing the adhesive surface is applied onto the backing layer, and wherein the backing layer has a higher in-plane stiffness than the planar layer of the elastic material.

2. The releasable surface-adhesive device of claim 1 , wherein the planar layer of the elastic material comprises two or more separate smaller elastic material layer units.

3. The releasable surface-adhesive device of claim 1 , further comprising a flexible tether attached to and extending from the backing layer of the adhesive pad.

4. The releasable surface-adhesive device of claim 3 , wherein an angle between the tether and the adhesive pad is adjustable.

5. The releasable surface-adhesive device of claim 3 , further comprising a holding component attached to the tether for connecting an object to the device.

6. The releasable surface-adhesive device of claim 3 , wherein the tether comprises at least one of fabric, rope, fiber, plastic sheet, tubing, rods, metal foil, chains, non-woven textile, cable, and leather.

7. The releasable surface-adhesive device of claim 3 wherein the tether is attached to the adhesive pad away from an edge of the adhesive pad.

8. The releasable surface-adhesive device of claim 3 , wherein the tether is attached to the adhesive pad at the center of the adhesive pad.

9. The releasable surface-adhesive device of claim 1 , wherein the planar layer of the elastic material has a uniform thickness between 0.0001 cm to 0.1 cm.

10. The releasable surface-adhesive device of claim 9 , wherein the elastic material has an elastic modulus between 0.05 MPa to 50 MPa.

11. The releasable surface-adhesive device of claim 10 , wherein the elastic material comprises at least one of a siloxane-based elastomer, an urethane-based elastomer, an acrylate-based elastomer, a polydimethylsiloxane (PDMS), a block copolymer elastomer, a polyurethane, styrene-butadiene-styrene, and a natural rubber.

12. The releasable surface-adhesive device of claim 11 , wherein the backing layer comprises at least one of a fabric, foil, sheet, and film.

13. A method comprising:
attaching a flexible tether to the adhesive pad of the releasable surface-adhesive device of claim 1 .
