摘要： A two-axis micro-electro mechanical system (MEMS) device includes a moving plate, a stage, a driving coil, a pair of magnets, and a yoke magnetic body. The moving plate is supported coaxially on a first axis to move pivotably about the first axis. The stage is supported coaxially on the second axis in an inner region of the moving plate. The driving coil includes a coaxial coil portion arranged along the first axis of the driving plate and divided at a center by the stage, and a first connecting coil portion and a second connecting coil portion. The yoke magnetic body is disposed between the pair of magnets in a region above or below the magnets and is formed of a material capable of being magnetized by the magnets in order to suddenly change a magnetic flux density according to a distance between the pair of magnets.
