Vibrating gyroscope including a pair of piezoelectric bodies with electrically floating interface |
摘要 |
A vibrating gyroscope includes a vibrating unit and a driving unit for driving the vibrating unit. The vibrating unit includes at least a pair of piezoelectric bodies stacked and polarized in a stacked direction thereof such that polarizing directions of the piezoelectric bodies are opposed to each other. An interface between the piezoelectric bodies is electrically floating with respect to a reference potential. The driving circuit receives at least one feedback signal from the vibrating unit and outputs to the vibrating unit a driving signal which has substantially the same phase as the feedback signal.
