Abstract

The invention provides unique releasable adhesive devices and related methods that are capable of simultaneously adhering to two or multiple target surfaces of various nature and allow high load capacity, are reusable, easy release and suitable for extended and repeated use.

Claims

1. A releasable surface-adhesive device comprising:

an adhesive pad comprising;

a planar backing layer; and

an elastic planar layer including an adhesive surface, wherein the elastic planar layer is applied to the backing layer on a side opposing the adhesive surface; and

a tether attached to and extending from a portion of the adhesive pad, wherein the tether, the planar backing layer, and the elastic planar layer form a continuous planar component.

2. The releasable surface-adhesive device of claim 1, wherein the backing layer has a higher in-plane stiffness than the elastic planar layer.

3. The releasable surface-adhesive device of claim 1, wherein the portion of the adhesive pad that the tether is attached to is located away from a center of the adhesive pad.

4. The releasable surface-adhesive device of claim 3, wherein the portion of the adhesive pad that the tether is attached to is located away from an edge of the adhesive pad.

5. The releasable surface-adhesive device of claim 1, wherein the tether is attached to the planar backing layer of the adhesive pad.

6. The releasable surface-adhesive device of claim 1, wherein the tether and backing layer are formed by a single continuous piece of material.

7. The releasable surface-adhesive device of claim 1, wherein a portion of the backing layer extends beyond the elastic planar layer.

8. The releasable surface-adhesive device of claim 1, wherein the backing layer is a fabric backing layer including at least one of cotton, hemp, wool, silk, bamboo string, cellulose, jute, and pina, polyester, spandex, nylon, carbon fiber, polyaramid, carbon fiber polyaramid hybrid, carbon fiber basalt hybrid, fiberglass, carbon fiber, and fiberglass hybrid.

9. A releasable surface-adhesive device comprising:

a first adhesive pad and a second adhesive pad, wherein each adhesive pad comprises;

an elastic planar layer including an adhesive surface; and

a tether attached to and extending between the first adhesive pad and the second adhesive pad, wherein the tether and the elastic planar layer of at least one of the adhesive pads form a continuous planar component.

10. The releasable surface-adhesive device of claim 9, wherein the tether and the elastic planar layer of both adhesive pads form a continuous planar component.

11. The releasable surface-adhesive device of claim 9, wherein each adhesive pad further comprises a planar backing layer, wherein the elastic planar layer is applied to the backing layer on a side opposing the adhesive surface, and wherein the tether, backing layer, and the elastic planar layer of each adhesive pad form the continuous planar component.

12. The releasable surface-adhesive device of claim 11, wherein the tether and the backing layer of at least one of the adhesive pads are formed by a single continuous piece of material.

13. The releasable surface-adhesive device of claim 11, wherein for each adhesive pad the backing layer has a higher in-plane stiffness than the associated elastic planar layer.

14. The releasable surface-adhesive device of claim 11, wherein the tether is attached to the planar backing layer of the first adhesive pad and the planar backing layer of the second adhesive pad.

15. The releasable surface-adhesive device of claim 11, wherein for at least one of the first adhesive pad and the second adhesive pad a portion of the backing layer extends beyond the elastic planar layer.

16. The releasable surface-adhesive device of claim 11, wherein each backing layer of at least one of the first adhesive pad and the second adhesive pad is a fabric backing layer including at least one of cotton, hemp, wool, silk, bamboo string, cellulose, jute, and pina, polyester, spandex, nylon, carbon fiber, polyaramid, carbon fiber polyaramid hybrid, carbon fiber basalt hybrid, fiberglass, carbon fiber, and fiberglass hybrid.

18. The releasable surface-adhesive device of claim 9, wherein the first adhesive pad and the second adhesive pad are attached to a same side of the tether.

19. A releasable surface-adhesive device comprising:

a first adhesive pad and a second adhesive pad, wherein each adhesive pad comprises;

a planar backing layer;

an elastic planar layer including an adhesive surface, wherein the elastic planar layer is applied to the backing layer on a side opposing the adhesive surface; and

a tether attached to and extending between the first adhesive pad and the second adhesive pad.

20. The releasable surface-adhesive device of claim 19, wherein for each adhesive pad the backing layer has a higher in-plane stiffness than the associated elastic planar layer.

21. The releasable surface-adhesive device of claim 19, wherein the tether is attached away from a center of at least one of the first adhesive pad and the second adhesive pad.

22. The releasable surface-adhesive device of claim 21, wherein the tether is attached away from an edge of at least one of the first adhesive pad and the second adhesive pad.

23. The releasable surface-adhesive device of claim 22, wherein the tether is attached away from both the edge and the center of both the first adhesive pad and the second adhesive pad.

24. The releasable surface-adhesive device of claim 21, wherein the tether is attached substantially at a center of at least one of the first adhesive pad and the second adhesive pad.

25. The releasable surface-adhesive device of claim 19, wherein the tether is attached to the planar backing layer of the first adhesive pad and the planar backing layer of the second adhesive pad.

26. The releasable surface-adhesive device of claim 19, wherein for at least one of the first adhesive pad and the second adhesive pad a portion of the backing layer extends beyond the elastic planar layer.

27. The releasable surface-adhesive device of claim 19, wherein each backing layer of at least one of the first adhesive pad and the second adhesive pad is a fabric backing layer including at least one of cotton, hemp, wool, silk, bamboo string, cellulose, jute, and pina, polyester, spandex, nylon, carbon fiber, polyaramid, carbon fiber polyaramid hybrid, carbon fiber basalt hybrid, fiberglass, carbon fiber, and fiberglass hybrid.
