The vibrating body is connected with excitation electrodes (4) and receiving electrodes (3), which are arranged along a part of a longitudinal extension of the vibrating body. The vibrating body is formed as longitudinal extending plate with a rectangular base or as plate with circular base. The domain-inverted area is formed as layer in the cross section of the vibrating body. USE - Piezoelectric sensor. ADVANTAGE - The piezoelectric sensor has a mono crystalline vibrating body from a piezoelectric material, in which a domain-inverted area is formed with inverted crystal axis, where the vibrating body is connected with excitation electrodes and receiving electrodes, which are arranged along a part of a longitudinal extension of the vibrating body, and hence enables manufacturing of piezoelectric sensor in an economical manner.de621Piezoelektrischer SensorPiezoelectric sensor, has mono crystalline vibrating body from a piezoelectric material, in which domain-inverted area is formed with inverted crystal axis, where vibrating body is connected with excitation and receiving electrodespatent102007009907
