Abstract
A highly sensitive oscillatory gyroscope that includes an elastic metal body in the form of a rectangular column having first to fourth sides. The elastic metal body includes a pair of end segments located at its ends and a pair of middle segments located at an upper middle portion and a lower middle portion of the elastic metal body. Each end segment has an opening extending from the second side to the fourth side, and each middle segment has an opening extending from the first side to the third side. A first ferroelectric substance film is provided on each of the first and third sides at the end segments. A second ferroelectric substance film is provided on each of the second and fourth sides at the middle segments. First and second electrodes are provided on each first ferroelectric substance film at each end segment. Third and fourth electrodes are provided on each second ferroelectric substance film at each middle segment.
