Abstract
An accelerometer with a mobile mass mechanically connected, via an insulator, to a conductive substrate by flexible beams. Mobile conductive teeth are integrally formed with the mobile mass. Fixed conductive teeth are joined to an insulator from the substrate and arranged in an alternating manner with the mobile conductive teeth. Fixed electrodes serving as an electrostatic screen are placed between the fixed teeth and the mobile teeth in such a way that each mobile tooth is intercalated between a fixed electrode and a fixed tooth so as to constitute a series of variable capacitance capacitors.
