비파괴센서 Non-Destructive Sensor
SiBULe 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.
- 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 single crystal 2-2, 1-3 composite element which is small, lightweight and conformal to hull shape for hydrophone and communication receiver on UUV or AUV or on a submarine.
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 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
A compact broadband ring transducer for the potential applications to underwater acoustic communications, countermeasure and ASW on UUV or AUV or on a submarine.
