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 ...

We wager you haven’t you heard the latest from ultrasonics. Sorry. [Lindsay Wilson] is a Hackaday reader who wants to share his knowledge of transducer tuning to make tools. The bare unit he uses to ...

In both developed and developing countries, advanced point-of-care diagnostic systems are needed for testing patients outside centralized hospital laboratories and other such facilities. Diseases such ...

• Trapped acoustic resonance is most simply described with an analogy: the ringing of a bell. • Microprocessors control the frequency of the mechanical resonance and monitors its decay. • A thicker ...
