To provide an improved bimorph actuator.SOLUTION: 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 is attached to the base.SELECTED DRAWING: Figure 89 【課題】改良されたバイモルフアクチュエータを提供する。【解決手段】ＳＭＡアクチュエータとその関連方法について説明される。アクチュエータの一実施形態は、ベースと、複数のバックルアームと、複数のバックルアームのうちの一対のバックルアームに結合された少なくとも第１形状記憶合金ワイヤとを含む。アクチュエータの別の実施形態は、ベースと、形状記憶合金材料を含む少なくとも１つのバイモルフアクチュエータとを含む。バイモルフアクチュエータはベースに取り付けられる。【選択図】図８９
