Abstract
A microactuator comprises a motor element including a stator and a rotor capacitively coupled to the stator; an actuator element having a circular structure; and a transmission structure interposed between the motor element and the actuator element to transmit a rotary movement of the motor element into a corresponding rotary movement of the actuator element. In particular, the transmission structure comprises a pair of transmission arms identical to each other, arranged symmetrically with respect to a symmetry axis of the microactuator. The transmission arms extend between two approximately diametrically opposed regions of the rotor to diametrically opposed regions of the actuator element.
