PIEZOELECTRIC MECHANICAL-ELECTRIC TRANSDUCER

摘要

The proposed piezoelectric mechanical-electric transducer contains a piezoelectric element shaped as a parallelepiped with four pairs of electrodes, a matching voltage amplifier, and a matching charge amplifier. Three pairs of the electrodes are arranged at the sides of the piezoelectric element that are parallel to the polarization vector. The forth pair of the electrodes is arranged at the sides of the piezoelectric element that are perpendicular to the polarization vector.
