A complete model was developed to simulate the behavior of a circular clamped axisymmetric fluid-coupled Piezoelectric Micromachined Ultrasonic Transducer (PMUT). Combining Finite Difference and Boundary Element Matrix (FD-BEM), this model is based o

International audience; The main challenge with Capacitive Micromachined Ultrasonic Transducer (CMUT) probes packaging is to preserve their intrinsic performances. Indeed, careful attention should be paid to the encapsulation of CMUTs and the impact

This work is an experimental validation of a new approach to design and to optimize the response of CMUT -based linear arrays. The method is applied to the design of linear arrays centered at 10 MHz. Two configurations, with two different spectral si

This paper describes the implementation of a new equivalent electroacoustic circuit for cMUT arrays. This circuit was obtained by using the normal mode theory. Theoretical simulations were also carried out from this new circuit to illustrate the impa

This paper describes a new way of using cMUT technology: galvanic isolation for power electronics. These devices work like acoustic transformers, except that piezoelectricity is replaced by cMUT technology. Primary and secondary circuits are two cMUT

Even though the CMUT technology is currently experiencing an exciting era in the field of ultrasonic imaging, few studies have assessed the real interest of this technology for therapeutic purposes compared to the state-of-the-art technology. Moreove
