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)
