Abstract: A linear system model is developed for a composite piezoelectric transducer with multiple matching layers. The large number of degrees of freedom in this model and the sensitivity of the ...

A research team has developed the world's first high-performance photoacoustic endoscopy based on a transparent ultrasonic ...

Abstract: Ultrasound is widely used in engineering and biology for applications such as ultrasonic cleaning, cutting, and cancer treatment. Piezoelectric ultrasonic transducers are widely used to ...

Applying a voltage supply to a piezoelectric crystal, it starts to vibrate and these vibrations generate sound waves with frequencies between 1.5 and 8 MHz (i.e ultrasound). Thus, piezoelectric ...

The proposed approach uses an ultrasound piezoelectric transducer glued to the bottom of a circular glass plate. A regular polystyrene cell culture dish is placed on top of the glass plate ...

Using a simple yet effective technique, researchers from Doshisha University could harness ultrasound vibrations generated by a piezoelectric transducer to control the orientation of cultured ...
