| 1. | Mineralization of the ultrasonic transducers requires maintenance and potential for component failure.
|
| 2. | Most of the commercial ultrasonic transducers today are based on piezoelectricity.
|
| 3. | Ultrasonic transducers showing ~ 20 kHz and ~ 40 kHz stacks.
|
| 4. | Ultrasonic transducers convert AC into ultrasound, as well as the reverse.
|
| 5. | This method works with an ultrasonic transducer scanning the wafer bond.
|
| 6. | The ultrasonic transducer raster-scans the top surface of the sample.
|
| 7. | The generated ultrasonic waves are detected by ultrasonic transducers and then analyzed to produce images.
|
| 8. | It may use microphones, accelerometers, and multifrequency ultrasonic transducers.
|
| 9. | It is used in a number of practical applications such as ultrasonic transducers and piezoelectric resonators.
|
| 10. | Each path consists of an ultrasonic transducer at one end and a sensor at the other.
