Roboticizing fabric by integrating functional fibers
Flattened heat-responsive Nitinol shape-memory alloys were used as the actuator. Field's metal-epoxy composite variable support fibers were incorporated into this to lend stiffness to the fabric when needed, such as when supporting a load. Finally, the fibers were painted with conductive ink that can sense the strain or bending of the fabric to help control and hold curvatures. By incorporating these fibers into conventional fabrics, the researchers developed a robotic tourniquet and shape-changing napkin-sized robotic sheet that automatically folds into a box capable of supporting 50 g of weight.
Established textile manufacturing processes could eventually be leveraged for the production of rolls of robotic fabric that could be used to make self-reconfiguring machinery. These fabrics present a means to create smart adaptable clothing, self-deployable shelters, and lightweight shape-changing machinery.
