Shape memory alloy bundles and actuators |
摘要 |
<p>A plurality of individual shape memory alloy (SMA) wires (12) are formed into a SMA bundle (10) to increase force output therefrom. The SMA bundle (10) has a parent shape and a deformed shape. The SMA bundle (10) in the deformed shape resumes its parent shape once the SMA bundle is heated to generate increased force output. The SMA wires (12) can be configured into strands (14), ropes (18), arrays (32) or other shapes. The SMA material is also used in a variety of actuators (50, 66, 92, 100, 130) for generating substantially continuous motion. <IMAGE></p> |
