摘要
The microactuator (30) comprises a motor element (32) including a stator (38) and a rotor (40) capacitively coupled to the stator (38); an actuator element (34) having a circular structure; and a transmission structure (36) interposed between the motor element (32) and the actuator element (34) to transmit a rotary movement of the motor element (32) into a corresponding rotary movement of the actuator element (34). In particular, the transmission structure (36) comprises a pair of transmission arms (80, 81) identical to each other, arranged symmetrically with respect to a symmetry axis (A) of the microactuator (30). The transmission arms (80, 81) extend between two approximately diametrically opposed regions of the rotor (40) to diametrically opposed regions (84) of the actuator element (34).
