Formation of charged ferroelectric domain walls with controlled periodicity

Alexander Tagantsev, Nava Setter, Dragan Damjanovic, Tomas Sluka, Petr Bednyakov

Charged domain walls in proper ferroelectrics were shown recently to possess metallic-like conductivity. Unlike conventional heterointerfaces, these walls can be displaced inside a dielectric by an electric field, which is of interest for future electronic ...

Effect of interfacial interactions on the electromechanical response of poly(vinylidene fluoride-trifluoroethylene)/BaTiO3 composites and its time dependence after poling

Jan-Anders Edvin Maansson, Véronique Michaud, Yves Leterrier, Dragan Damjanovic, Sara Dalle Vacche

Solvent cast and compression molded composite films based on poly(vinylidene fluoride-trifluoroethylene), containing pristine and silylated BaTiO3 particles, were poled, and their electromechanical response (d(33)), their dielectric properties, and the cry ...

Monitoring of composite structures using a network of integrated PVDF film transducers

Thomas Gmür, Joël Cugnoni, Enrique René Guzman Solares

Aiming to reduce costs, polyvinylidene difluoride (PVDF) film patches are an emerging alternative to more classic piezoelectric technologies, like ceramic patches, as transducers to measure local deformation in many structural applications. This choice is ...

Experimental method for the evaluation of the dynamic transfer matrix using pressure transducers

François Avellan, Andres Müller, Keita Yamamoto

This paper introduces an experimental method for the evaluation of dynamic transfer matrices using only pressure transducers. The discharge fluctuations are evaluated from the fluctuation of the pressure difference at different streamwise locations. The tr ...

Toward broadband electroacoustic resonators through optimized feedback control strategies

Hervé Lissek, Romain Boulandet

This paper presents a methodology for the design of broadband electroacoustic resonators for low-frequency room equalization. An electroacoustic resonator denotes a loudspeaker used as a membrane resonator, the acoustic impedance of which can be modified t ...

A 10.5 cm Ultrasound Link for Deep Implanted Medical Devices

Catherine Dehollain, Francesco Mazzilli

A study on ultrasound link for wireless energy transmission dedicated to deeply implanted medical devices is presented. The selection of the frequency to avoid biological side effects (e. g., cavitations), the choice of the power amplifier to drive the ext ...
