Abstract:
1. A microelectromechanical device comprising: a microstructure having a fixed structure and a movable mass, capacitively and mechanically coupled to the fixed structure and movable between a rest position and a maximum extension position; a reading interface configured to detect a position of the movable mass; a first line configured to supply a first voltage; a second line configured to supply a second voltage; a configuration stage configured to switch between a first configuration, in which the configuration stage electrically couples the reading interface to the microstructure, and a second configuration, in which the configuration stage electrically decouples the reading interface from the microstructure and couples the fixed structure to the first line, the configuration stage having: a bias element configured to selectively electrically couple the movable mass to the second line; and a control unit structured to switch the configuration stage between the first and the second configuration and structured to cause the bias element to electrically couple the movable mass to the second line when the configuration stage is in the second configuration and thereby move the movable mass to the maximum extension position.
