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 and two matching voltage amplifiers. The output of the first amplifier that is used as the output amplifier of the transducer is connected to the electrode that is arranged at the side of the piezoelectric element that is perpendicular to the polarization vector. The input of the first amplifier, the input and the output of the second amplifier are connected to the corresponding electrodes that are arranged at the side that is parallel to the polarization vector. The remaining electrodes are connected to the common point of the transducer circuit.
