Piezoelectric ultrasonic transducers play a critical role in modern sensing and actuation by converting electrical signals into high‐frequency mechanical vibrations and vice versa. Recent advances ...

Today, a vast number of micro-manufactured sensors, actuators and components vibrate at frequencies in the high MHz range. Some examples of these high-frequency vibrating systems include surface ...

The vibrations are said to only produce a soft whispering noise, although the knife itself does beep to let users known when it's actually cutting. When not in use, it gets covered with a blade guard ...

Most ultrasonic flaw detection and thickness gaging are carried out at normal temperatures. However, sometimes a hot material requires testing, for example, in process industries. In these instances, ...
