Current miniaturized ultrasound transducers suffer from insufficient attenuation from the backing layer due to their limited thickness. The thickness of the backing layer is one of the critical ...

The prototype ultrasound transducer Adapted from ACS Sensors 2025, DOI: 10.1021/acssensors.5c00521 ...

However, a major limitation is that each focused ultrasound transducer has a fixed focal length. This means that multiple transducers with different focal lengths must be purchased, leading to ...

The transducer then converts the reflected sound waves into an image. Currently, most ultrasound transducers have large heads that are about the same size as a wireless earbuds case.

Ultrasound-guided high intensity focused ultrasound (HIFU) treatment has been studied to determine accurate positions of the regions to be treated and to monitor its treated volume. However, in most ...

In another study, a flexible, high-intensity transducer employing a candle soot nanoparticles and PDMS nanocomposite was fabricated, demonstrating markedly improved signal-to-noise ratios and the ...
