Abstract
Angular sensor with vibrating resonator includes a supporting structure, a first mass and a second mass which are concentric, and mechanical springs arranged symmetrically in pairs, the pairs themselves being arranged symmetrically with respect to one another. Each spring comprises a first elastic leaf and a second elastic leaf which are connected to one another by one end, the first elastic leaf of one of the springs of each pair being parallel to the second elastic leaf of the other of the springs of the same pair. The four elastic leaves of at least one pair comprise two adjacent pairs of leaves making an angle of approximately 45° between them. The sensor is not provided with electrostatic springs.
