Morphable body
A body can be configured to be selectively morphable. One or more body support members can be operatively connected to an outer surface of the body. The one or more body support members can be arranged in a pattern to define at least one morphing region. A contracting member (e.g., a shape memory polymer) can be operatively connected to the outer surface of the body. When activated, the contracting member can contract, which can cause the body to morph (e.g., bend) from a non-activated configuration into an activated configuration.
1. A morphable body comprising:
a body, the body being inflatable; and
one or more body support members operatively connected to the body, the one or more body support members being arranged in a first pattern to define a morphing region and in a second pattern to define a non-morphing region, the first pattern including a plurality of linear segments that are substantially parallel to each other, the second pattern including a grid pattern with a first plurality of linear segments and a second plurality of linear segments that are transverse to each other; and
a contracting member operatively connected to the body, the contracting member being a shape memory material,
when activated, the contracting member contracts to cause the body to morph from a non-activated configuration into an activated configuration, and
when subsequently deactivated, the contracting member maintains the activated configuration of the body.
2. The morphable body of claim 1 , wherein, when subsequently re-activated, the contracting member relaxes to cause the body to substantially return to the non-activated configuration.
3. The morphable body of claim 1 , further including a sleeve received within a hollow interior of the body, and wherein the sleeve is air impermeable, whereby the body is inflatable.
4. The morphable body of claim 1 , wherein the body is made of an air impermeable fabric, whereby the body is inflatable.
5. The morphable body of claim 1 , wherein, in the first pattern, the plurality of linear segments are substantially perpendicular to a direction of elongation of the body.
6. The morphable body of claim 1 , wherein the shape memory material is a shape memory polymer.
7. A system comprising:
a morphable body including:
a body, the body being inflatable;
one or more body support members operatively connected to the body, the one or more body support members being arranged in a first pattern to define a morphing region and in a second pattern to define a non-morphing region, the first pattern including a plurality of linear segments that are substantially parallel to each other, the second pattern including a grid pattern with a first plurality of linear segments and a second plurality of linear segments that are transverse to each other; and
a contracting member operatively connected to the body,
when activated, the contracting member contracts to cause the body to morph from a non-activated configuration into an activated configuration, the contracting member being a shape memory material,
when subsequently deactivated, the contracting member maintains the activated configuration of the body; and
a processor operatively connected to cause the contracting member to be activated and deactivated.
8. The system of claim 7 , further including one or more inflation sources operatively connected to inflate the body, and wherein the processor is operatively connected to control a supply of fluid from the one or more inflation sources to the body.
9. The system of claim 7 , further including one or more power sources operatively connected to the contracting member, and wherein the processor is operatively connected to control a supply of electrical energy from the one or more power sources to the contracting member.
10. The system of claim 9 , wherein causing the contracting member to be activated includes
causing electrical energy to be supplied to the contracting member from the one or more power sources, and
wherein causing the contracting member to be deactivated includes causing the supply of electrical energy to the contracting member to be discontinued.
11. The system of claim 7 , wherein the processor is further configured to:
cause the contracting member to be reactivated, whereby the body substantially returns to the non-activated configuration.
12. The system of claim 7 , further including a sleeve received within a hollow interior of the body, and wherein the sleeve is air impermeable, whereby the body is inflatable.
13. The system of claim 7 , wherein the body is made of an air impermeable fabric, whereby the body is inflatable.
14. The system of claim 9 , wherein the plurality of linear segments of the first pattern are substantially perpendicular to a direction of elongation of the body.
15. The system of claim 7 , wherein the shape memory material is a shape memory polymer.
16. A method of controlling a morphable body that is inflatable, the morphable body including a body, one or more body support members operatively connected to the body, the one or more body support members being arranged in a first pattern to define a morphing region and in a second pattern to define a non-morphing region, the first pattern including a plurality of linear segments that are substantially parallel to each other, the second pattern including a grid pattern with a first plurality of linear segments and a second plurality of linear segments that are transverse to each other, and a contracting member operatively connected to the body, the contracting member being a shape memory material, the method including:
activating the contracting member such that the contracting member contracts to cause the body to morph from a non-activated configuration into an activated configuration; and
subsequently deactivating the contracting member such that the activated configuration of the body is maintained by the contracting member.
17. The method of claim 16 , further including:
re-activating the contracting member such that the contracting member relaxes to cause the body to substantially return to the non-activated configuration.
