10. The adaptive article of apparel of claim 1 , wherein the adaptive article of apparel is a hat.
11. The adaptive article of apparel of claim 1 , wherein the adaptive article of apparel is a sleeve configured to be worn around an arm or leg of the wearer.
12. The adaptive article of apparel of claim 1 , wherein the opening comprises an opening or aperture portion of a pocket that is in or coupled to the adaptive article of apparel.
13. A method, comprising:
forming a textile having an opening configured to admit a body part of a wearer; and
securing an electroadhesive clutch to the textile, the electroadhesive clutch extending around at least a portion of the opening, the electroadhesive clutch comprising:
a first electrode assembly comprising a first conductive member;
a second electrode assembly comprising a second conductive member overlaying in part the first conductive member; and
an electrical signal generator configured to provide first and second signals to the first and second conductive members of the first and second electrode assemblies, respectively, wherein the first electrode assembly is configured to slide laterally relative to the second electrode assembly when the first and second signals are not applied and remain static relative to the second electrode assembly when the first and second signals are applied;
wherein the electroadhesive clutch is configured to inhibit increasing a size of the opening when the first and second signals are applied to the first and second electrode assemblies.
14. The method of claim 13 , wherein the electroadhesive clutch further comprises a waterproof encasing within which the first and second electrode assemblies are positioned.
15. The method of claim 14 , wherein the waterproof encasing is an elastic waterproof encasing configured to return the first and second electrode assemblies to a relaxed position when force is not placed on the elastic waterproof encasing.
16. The method of claim 13 , wherein the textile is a waterproof textile and wherein the textile is configured to form a watertight seal around the first and second electrode assemblies.
