Abstract
This disclosure reveals a resonator where at least one suspended inertial mass is driven into rotational oscillation by a piezoelectric drive transducer, or where the rotational motion of at least one suspended inertial mass is sensed by a piezoelectric sense transducer. The disclosure is based on the idea of suspending the inertial mass with a one-sided suspender arrangement, where only one suspender is attached to each anchor point, and on the optimal positioning of the suspender in relation to the effective center of gravity of the resonator. The resonator may be employed in a resonator system, a clock oscillator or a gyroscope.
