Piezoelectric Single Crystal Property Assessment for Cost-Effective Optimized Naval SONAR Transducers

This SBIR Proposal addresses the need for a"Piezoelectric Single Crystal Property Assessment for Cost-Effective Optimized Naval SONAR."We have identified a SONAR transducer application that will benefit from this effort in which a characterization of the linear and non-linear electromechanical properties will be undertaken over a broad range of temperature-field-stress conditions. To this end we will utilize a targeted array of instruments specifically set up for these measurements. The experimental piezoelectric single crystal sample setup will be tracked with 3-D finite element models to ascertain the suitability of sample size, particularly in relationship to the modes of vibration. The measurements will then be applied to both linear and non-linear analytical and piece- wise finite element models. Ultimately, this data would be used to predict the full performance of the identified SONAR transducer application.
