# Auxetic shape memory material (smm) deformable structure

## Abstract

Structures, systems, methods, and other embodiments described herein relate to selectively deformable bodies. In one embodiment, a deformable structure includes an expandable tube of a shape memory material (SMM) arranged in an auxetic pattern. The SMM becomes deformable responsive to an activation input. The deformable structure also includes a first heating element within an interior volume of the expandable tube. The first heating element activates the SMM. The deformable structure also includes an inflatable structure within the interior volume of the expandable tube, to selectively deform the SMM when activated.
