Abstract
SMA actuators and related methods are described. One embodiment of an actuator includes a base; a plurality of buckle arms; and at least a first shape memory alloy wire coupled with a pair of buckle arms of the plurality of buckle arms. Another embodiment of an actuator includes a base and at least one bimorph actuator including a shape memory alloy material. The bimorph actuator attached to the base.
Claims6
An actuator comprising:
- a plurality of bimorph arms configured to reduce a net friction force of the plurality of bimorph arms, wherein the plurality of bimorph arms are arranged in a reversed inline orientation, the reverse inline orientation including:
- a first bimorph arm of the plurality of bimorph arms and a second bimorph arm of the plurality of bimorph arms, the second bimorph arm arranged inline with the first bimorph arm such that a fixed end of the first bimorph arm is positioned at an end of the actuator that is opposite from an end of the actuator that is adjacent to a fixed end of the second bimorph arm.
An actuator comprising:
- a plurality of bimorph arms configured to reduce a net friction force of the plurality of bimorph arms, wherein the plurality of bimorph arms are arranged in a staggered orientation.
Dependencies are inferred from the claim text.
