Abstract
A transducer for measuring an angular velocity formed by a single piezoelectric tuning fork (21) that rotates at the angular velocity. The tuning fork has a detection leg (24) which has a cross-shaped section including two top lateral faces (33, 34) and two bottom lateral faces (37, 38) separated by protruding parts (41, 42) projecting with respect to the faces. The detection leg has detecting electrodes which are arranged such that the electrical field between electrodes is substantially rectilinear through the detection leg.
