Shape-Morphing Space Frame (SMSF) Using Linear Bistable Elements

USF inventors have invented an improved structure that provides a controllable space-frame change (e.g., used in shape shifting surfaces) that allows the morphing of one specific shape into a different shape. The frame’s initial shape is constructed from a single layer grid of flexures, rigid links. The grip is then bent into the space frames initial cylindrical shape which can morph because of the inclusion of Linear Bi-stable Compliant Crank–Slider Mechanism (LBCCSM) in its structure. The ability to change the surface profile upon actuation can be implemented in various applications, such as deployable antennas, airplane wings, morphing, and fluid flow controllers. There is potential for this method to be manufactured at the micro-scale to be used in medical applications, such as intravascular stent.
