수중음향센서 Underwater Acoustic Sensors
iBULe has been actively involved in the various research projects in defense and industrial applications such as SONAR transducers, NDT(Non-destructive Testing) probes, actuator, IR sensor, energy harvesting devices, accelerometer, and so on.
NUWC, Office of Naval Research(ONR) Lynn M. Ewart, et, al The International Symposium on Piezocrystals and their Applications July 22, 2015
Increase in bandwidth and range (50% higher coupling constants over PZT)
Less electric input power (650% higher piezoconstants over PZT)
Reduction in overall transducer size (78% lower elastic modulus over PZT)
Strong anisotropy (piezo properties optimization by domain engineering)
A transducer using 2-2, 1-3 composite single crystal for the potential applications to a SAS projector with a wider bandwidth and be capable of working at lower frequency than the existing one.
A compact broadband ring transducer for the potential applications to underwater acoustic communications, countermeasure and ASW on UUV or AUV or on a submarine.
A Cylindrical hydrophone and two orthogonally mounted cantilever beam accelerometers inside the cylinder. Compact size and Light weight vector sensor compatible with the TAS in use
Over 50 stacking of single crystal which is small size and large displacements for actuator such as ‘Deformable Mirror’. (6.7um@100V)
