摘要：
Parametric transducers may be used to monitor vibrational modes of resonant-mass Gravitational Wave (GW) detectors. This work focuses on the development and optimization of electromechanical transducers for the brazilian GW detector "Mario Schenberg" We present the design and preliminary results for the optimization process of the last generation of the Schenberg parametric transduction system. Thanks to the results obtained from the last run of tests improvements for the transduction system will be planned and performed, in order to make the detector suitable for the searching of GW signals. The aim would be to obtain information about the direction and polarization of waves produced by astrophysical sources in the frequency bands of the spherical detector resonant modes.
