ELECTRICAL-TO-MECHANICAL TRANSDUCER

摘要

The proposed piezoelectric mechanical-electric transducer contains a piezoelectric element shaped as a parallelepiped with two pairs of electrodes and two matching charge amplifiers. The input and the output of the amplifier that is used as the output amplifier of the transducer are connected to the electrodes that are arranged at the sides of the piezoelectric element that are perpendicular to the polarization vector. The input and the output of the second amplifier are connected to the electrodes that are arranged at the sides that are parallel to the polarization vector. The force applied to the piezoelectric element is parallel to the polarization vector.
