Abstract
Described herein is a method for testing a microelectromechanical device provided with a microstructure having a fixed structure and a movable mass, which is capacitively coupled to the fixed structure and mechanically connected thereto so as to be movable between a rest position and at least one position of maximum extension. The method envisages: applying a test voltage between the movable mass and the fixed structure so as to set up an electrostatic force between them and displace the movable mass into the position of maximum extension; keeping the movable mass in the position of maximum extension for a time interval; releasing the movable mass from the position of maximum extension; and detecting a current position of the movable mass.
