Development of PZT-based 18 MHz 2D pMUT array with PDMS waveguide

Xu-Bo Wang, Le-Ming He, Wen-Juan Liu, Shu-Ren Song, Wei-Jiang Xu, Qian Cheng, Antoine Riaud, Jun-Yan Ren, Jia Zhou

For high-resolution ultrasonic imaging, an 18 MHz lead zirconate titanate (PZT) based two-dimensional (2D) piezoelectric micromachined ultrasonic transducers (pMUTs) array with polydimethylsiloxane (PDMS) waveguide are developed. The array is composed of 8 x 16 elements with a pitch of 75 mu m and…

Atomic Structure of Glassy GeTe 4 as a Playground to Assess the Performances of Density Functional Schemes Accounting for Dispersion Forces

Pier Luigi Silvestrelli, Évelyne Martin, Mauro Boero, Assil Bouzid, Guido Ori, Carlo Massobrio

The atomic structure of glassy GeTe4 is obtained in the framework of first-principles molecular dynamics (FPMD) by considering five different approaches for the description of the electronic structure within density functional theory (DFT). Among these schemes, one is not corrected by accounting…

Multiple sequential constraint removal algorithm for channel estimation in vehicular environment

Soheyb Ribouh, Yassin El Hillali, Atika Rivenq

Since the vehicular environment is highly mobile, the transmitted messages are affected by the wireless channel effect. This makes channel estimation one of the important tasks in Vehicle-To-Everything (V2X) communications. In this paper, we propose a novel Multiple Sequential Constraint Removal (…

Experimental Characterization of A Piezoelectric Transducer Array Taking into Account Crosstalk Phenomenon

Abdelmajid Bybi, Driss Khouili, Christian Granger, Mohammed Garoum, Ahmed Mzerd, Anne-Christine Hladky

Ultrasonic transducer arrays are generally composed of several piezoelectric elements arranged in 1D or 2D ways. Crosstalk is an undesirable phenomenon decreasing the performance of these devices. It generates parasitic displacements at the elements' radiating surfaces, which changes the…
