Greg Blonder. "Phase change composite bimorphs." U.S. Patent application 15/663, 334.Abstract
A bilayer composite thin-film beam structure is described. The structure incorporates a bulk phase change material as small inclusions in one layer of a bimorph. The structure, also referred to as a “phase change composite bimorph” or “PCBM”, curls abruptly, and reversibly, at a phase transition temperature. Large curling and effective expansion coefficients are demonstrated. The PCBMs may be employed in various self-assembly mechanisms and actuators.
