Abstract
A microelectromechanical device that includes a fixed supporting body, at least one semiconductor body, which is movable with respect to the fixed supporting body, and at least one micromotor for moving the semiconductor body with respect to the fixed supporting body, the micromotor having at least one permanent magnet and a coil, which are coupled together and are movable with respect to one another. A ferromagnetic guide is coupled to the magnet and is shaped so as to concentrate lines of magnetic field generated by the magnet towards the coil.
