双向微机电驱动装置
摘要：
本发明涉及一种微机电系统(MEMS)驱动装置，其包括：从动轮，所述从动轮包括围绕其外部周边的(n)个齿；围绕从动轮的致动器环，所述致动器环自身包括围绕其内部周边的(n)+(x)个齿，其中，致动器环的(n)+(x)个齿渐进地接合和脱离从动轮的(n)个齿的子集；驱动致动组件，所述驱动致动组件联接到致动器环，用于在滞后型的运动中驱动致动器环，从而促使从动轮转动，其中，在从动轮的(n)个齿的所选子集与致动器环的(n)+(x)个齿的所选子集之间接合和脱离的一个完整循环之后，从动轮转动了与[(360)(x)/(n)]°相对应的(x)个齿。
摘要（英）：

A micro-electromechanical system (MEMS) driving arrangement comprising a driven wheel comprising (n) teeth about an outer periphery thereof, an actuator ring around the driven wheel, itself comprising (n)+(x) teeth about an inner periphery thereof, wherein the (n)+(x) teeth of the actuator ring progressively engage and disengage subsets of the (n) teeth of the driven wheel; a driving actuation assembly, coupled to the actuator ring, for driving the actuator ring in a hysteresis-type motion so as to cause rotation of the driven wheel, wherein after one full cycle of engagements and disengagements between selective subsets of the (n) teeth of the driven wheel with selective subsets of the (n)+(x) teeth of the actuator ring, the driven wheel rotates by (x) teeth corresponding to [(360)(x)/(n)]°.
