A single axis rate sensor including a substantially planar vibratory resonator (1) having a substantially ring or hoop-like structure with inner and outer peripheries (1a, 1b) extending around a common axis (z) drive means (6) for causing the resonator (1) to vibrate in a Cos 2theta vibration mode, carrier mode pick-off means (7) for sensing movement of the resonator (1) in response to said drive means pick-off means (9) for detecting Sin 2theta vibration mode motion induced by rotation around the Z-axis, Sin 2theta vibration mode drive means (8) for nulling said motion and support means (2) for flexibly supporting the resonator (1) and for allowing the resonator (1) to vibrate relative to the support means (2) in response to the drive means, or to applied rotation wherein the support means comprises only L support beams, where L<>2<K>, and K=0, 1,2 or 3.
