An ultrasonic machine uses sound waves to clean retainers, mouth guards, and other dental pieces. Here’s how to decide if one is right for you.

In order to improve the performance of ultrasonically catalyzed gas sensors, this work proposed a novel structure of ultrasonic transducer for the ultrasonically catalyzed gas sensing system, and ...

Moreover, in ultrasonic imaging, the transmitting sound field of the point-focused transducer is very uneven, meaning that the ultrasonic trigger signal cannot effectively reach the target in the ...

In this study, a compact multi-element ultrasonic transducer was designed and fabricated for the inspection of split pins, which are the key connecting parts of the internal components in the reactor ...

The card provides a 100-MHz sampling rate and a 50-MHz input analog bandwidth required by the speed of the ultrasonic transducer. Figure 1 is a schematic diagram of the system.
