Abstract: A micro-electromechanical apparatus includes a rotary element, at least one restraint and at least two folded springs. The rotary element is capable of rotating with respect to an axis. The folded springs are symmetrically disposed about the axis. Each folded spring has a moving end and a fixed end, the moving end is connected to the rotary element, and the fixed end is connected to the at least one restraint. The moving end is not located on the axis, and the fixed end is not located on the axis. A moving distance is defined as a distance between the moving end and the axis, a fixed distance is defined as a distance between the fixed end and the axis. A spring length is defined as a distance between the moving end and the fixed end. The spring length is varied according to the rotation of the rotary element.

Abstract translation: 微机电装置包括旋转元件，至少一个约束件和至少两个折叠弹簧。 旋转元件能够相对于轴线旋转。 折叠弹簧围绕轴对称设置。 每个折叠弹簧具有移动端和固定端，移动端连接到旋转元件，并且固定端连接到至少一个约束。 移动端不在轴上，固定端不在轴上。 移动距离被定义为移动端和轴之间的距离，固定距离被定义为固定端与轴之间的距离。 弹簧长度被定义为移动端与固定端之间的距离。 弹簧长度根据旋转元件的旋转而变化。
