Abstract

Gyromètre micromécanique résonant comportant un support (2) et une masse mobile (4) apte à vibrer dans un plan du gyromètre par rapport au support (2), des moyens d'excitation (8) de ladite masse mobile (4) dans une première direction (X) et des moyens de détection (10) de la vibration de ladite masse mobile (4) dans une deuxième direction (Y), caractérisé en ce que le gyromètre comporte au moins un pied (6) ancré sur le support (2) par une première extrémité et fixé à la masse mobile (4) par une deuxième extrémité, et permettant à la masse mobile (4) de vibrer dans le plan du gyromètre le long des première(X) et deuxième (Y) directions.
