Abstract:
1. A microelectromechanical device comprising: a first structural element; a second structural element movable with respect to said first structural element, the second structural element including a trench facing a side of the second structural element; an elastic supporting structure extending between said first and second structural elements and configured to enable a relative movement between said first and second structural elements; and an anti-stiction structure including a flexible element fixed to the second structural element and, in a rest condition thereof, arranged at a first distance from the first structural element, said anti-stiction structure being configured to generate a repulsive force between the first and the second structural elements prior to the first and the second structural elements contacting each other and after a relative movement of an amount greater than said first distance, said flexible element extending within the trench and having an elongated shape with a first end portion fixed to said second structural element and a second end portion provided with a protruding portion facing and arranged at said first distance from said first structural element.
