Claim 10:
11. A microelectromechanical (MEMS) device, comprising:
a die having a cavity defined therein;
an anchorage portion formed by the die;
a tiltable structure elastically suspended over the cavity;
first and second supporting arms extending between the anchorage portion and opposite sides of the tiltable structure; and
first and second resonant piezoelectric actuation structures configured to cause rotation of the tiltable structure;
wherein the first supporting arm comprises first and second torsion springs, the first torsion spring being coupled to the tiltable structure, the second torsion spring being coupled to the anchorage portion, the first and the second torsion springs being coupled together at a first constraint region.
