Characteristics of a 2-2 Piezoelectric Composite Transducer Made by Magnetic Force Assembly
A wider operational bandwidth, a higher electromechanical coupling factor, and lower acoustic impedance are important requirements for ultrasound transducers for use across many applications. Conventional 2-2 piezoelectric composite transducers have been

Performance of periodic piezoelectric composite arrays incorporating a passive phase exhibiting anisotropic properties [PDF]
This paper explores the minimisation of interelement cross talk in 1-D and 2-D periodic composite array structures through the incorporation of a passive phase exhibiting anisotropic elastic properties.

Real‐Time 3D Ultrasound Imaging with an Ultra‐Sparse, Low Power Architecture
This article presents a novel, ultra‐sparse ultrasound architecture that paves the way for wearable real‐time 3D imaging. By integrating a unique convolutional array with chirped data acquisition, the system achieves high‐resolution volumetric scans at a fraction of the power and hardware complexity.

A generalised approach to torsionality maximisation in longitudinal-torsional ultrasonic devices [PDF]
A longitudinal-torsional vibration mode has many applications in ultrasonic systems. Obtaining this behaviour could be achieved either by coupling the longitudinal and torsional modes or by degenerating the longitudinal mode, but the results may be ...
