Abstract

A micro-electro-mechanical sensor includes a microstructure having a mass which is movable with respect to a rest position, according to a predetermined degree of freedom, and a displacement-detecting device for detecting a displacement of the mass according to the predetermined degree of freedom. The displacement-detecting device includes a force feedback loop of a purely analog type, which supplies electrostatic forces tending to restore the mass to the rest position in response to a displacement of the mass according to the predetermined degree of freedom.
