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)]°. |
