Capacitive micromachined ultrasonic transducer (CMUT) arrays for medical imaging
Alessandro Caronti,Giosue Caliano,Riccardo Carotenuto,Riccardo Carotenuto,Alessandro Stuart Savoia,Massimo Pappalardo,Elena Cianci,Vittorio Foglietti +7 more
TL;DR: This paper summarizes the fabrication, design, modeling, and characterization of 1D CMUT linear arrays for medical imaging, established in laboratories during the past 3 years, and indicates these devices as new generation arrays for acoustic imaging.

An accurate model for capacitive micromachined ultrasonic transducers
TL;DR: It is demonstrated that the compression of theAir has a significant effect on the fundamental frequency of the air transducer, with a deviation of about 22% from the prediction of a model that does not consider the interaction between the vibrating diaphragm and the air cushion.

Design, fabrication and characterization of a capacitive micromachined ultrasonic probe for medical imaging
Giosue Caliano,Riccardo Carotenuto,Elena Cianci,Vittorio Foglietti,Alessandro Caronti,Antonio Iula,Massimo Pappalardo +6 more
TL;DR: The design, fabrication process, and characterization of a 64-elements capacitive micromachined ultrasonic transducer (cMUT), 3 MHz center frequency, 100% fractional bandwidth, and a linear probe for application in medical echographic imaging are reported.

Finite element three-dimensional analysis of the vibrational behaviour of the Langevin-type transducer.
TL;DR: A 3D finite element analysis of the Langevin transducer's behaviour operating in the underwater sonar range of frequencies (30-140 kHz) is presented to gain insight into the coupling phenomenon between thickness-extensional and radial modes.

A high-power traveling wave ultrasonic motor
Antonio Iula,Massimo Pappalardo +1 more
TL;DR: The vibrational behavior of the stator as well as the traveling wave generation has been simulated with the finite-element method (FEM) software.
