Abstract
An actuation device () includes a plurality of actuation units () disposed about an axis (Ar). Each actuation unit of the plurality of actuation units () includes a shape memory alloy component (-), an auxetic material component (-) operationally coupled to the shape memory alloy component (-), and a power source (-) operationally coupled to the shape memory alloy component (-). Additionally, the actuation device () includes a control system () operationally coupled to the power source (-), the control system () is configured to actuate the shape memory alloy component (-) through the power source (). Further, when actuated, the shape memory alloy component (-) moves in a direction outward from the axis (Ar) to pull the auxetic material component (-), and the auxetic material component expands in a direction perpendicular to the movement direction of the shape memory alloy component (-).
