Abstract
A microelectromechanical device has a mobile mass that undergoes a movement, in particular a spurious movement, in a first direction in response to an external event; the device moreover has a stopper structure configured so as to stop said spurious movement. In particular, a stopper element is fixedly coupled to the mobile mass and is configured so as to abut against a stopper mass in response to the spurious movement, thereby stopping it. In detail, the stopper element is arranged on the opposite side of the stopper mass with respect to a direction of the spurious movement, protrudes from the space occupied by the mobile mass and extends in the space occupied by the stopper mass, in the first direction.
