Disclosed is a piezoelectric gyroscope which presents as a generally elongated tubular shape having inner and outer radially polarized annular region defining surfaces, with an inner electrode on the inner surface, and four outer electrodes present on the outer surface. The four electrodes present on the outer surface are oriented such that each is in a separate quadrant, (as the piezoelectric gyroscope generally longitudinally elongated essentially tubular structure is viewed in cross-section), and ideally at substantially ninety degree intervals on the outer surface. In use the piezoelectric gyroscope system is caused to rotate about an essentially centrally located longitudinally oriented axis while a flex inducing driving voltage is applied across two of the four electrodes, (driving) electrodes, which are oriented at substantially 180 degrees with respect to one another, while an output voltage is sensed across the other two (sensing), electrodes. Also disclosed are a tuning-fork shaped variations.
