Dual axial gyroscope with piezoelectric ceramics

摘要

A piezoelectric device is used in an dual axial gyroscope system and includes a piezoelectric exciter for generating a linear velocity on a first axis; a first piezoelectric detector element, placed on a surface of the piezoelectric exciter in a direction orthogonal to the first axis, for detecting a first Coriolis force provided in a direction orthogonal to the first detector; and as second piezoelectric detector element, placed on the surface of the piezoelectric exciter in a direction orthogonal to the first axis and the first detector, for detecting a second Coriolis force provided in a direction orthogonal to the second detector element.
