Rotational micro-electromechanical (mems) structure with parallel electrodes

A rotational micro-electro-mechanical structure includes a stator (21), having a plurality of stator electrodes (33, 34), and a rotor (23), which is rotatable with respect to the stator (21) about an axis of relative rotation (A) and has a plurality of rotor electrodes (30), the stator electrodes (33, 34) and the rotor electrodes (30) being comb-fingered; moreover, at least a first group (20a) of stator electrodes (33, 34) and rotor electrodes (30) are parallel to a first plane (P1) that includes the axis of relative rotation (A).
