Capacitive microwave sensor for toxic vapor detection in an atmospheric environment

P. Bahoumina, H. Hallil, K Pieper, J. Lachaud, D. Rebière, C. Dejous, A. Abdelghani, Kamel Frigui, Stéphane Bila, D. Baillargeat, Q. Zhang, P. Coquet, E. Pichonat, H. Happy

This paper presents an inkjet printing capacitive microwave sensor for toxic vapor detection. The designed sensors were presented and fabricated with success. The experiments show sensitivity to ethanol vapor according to the S parameters. It is equal to 0.9 kHz/ppm and 1.3 kHz/ppm for the sensors...

Selective Manipulation of Microscopic Particles with Precursor Swirling Rayleigh Waves

Antoine Riaud, Michael Baudoin, Olivier Bou Matar, Loic Becerra, Jean-Louis Thomas

Contactless manipulation of microparticles is demonstrated with single-beam acoustical tweezers based on precursor swirling Rayleigh waves. These surface waves degenerate into acoustical vortices when crossing a stack made of a fluid layer and its solid support, hence creating a localized...

Characterization of peptide attachment on silicon nanowires by X-ray photoelectron spectroscopy and mass spectrometry

Ievgen Kurylo, Mathieu Dupré, Sonia Cantel, Christine Enjalbal, Hervé Drobecq, Sabine Szunerits, Oleg Melnyk, Rabah Boukherroub, Yannick Coffinier

In this paper, we report an original method to immobilize a model peptide on silicon nanowires (SiNWs) via a photolinker attached to the SiNWs’ surface. The silicon nanowires were fabricated by a metal assisted chemical etching (MACE) method. Then, direct characterization of the peptide...

Détermination de l'état de mouillage aux échelles micro/nano par caractérisation acoustique haute fréquence.

Christophe Virgilio, Malika Toubal, Pierre Campistron, Vincent Thomy, Bertrand Nongaillard, Philippe Garnier, Lucile Broussous, Julien Carlier

Les ondes acoustiques ultrasonores dans la gamme du GHz sont exploitées dans les pour réaliser l'imagerie de propriétés élastiques à l'échelle microscopique. Il est, dans ce cas, possible d'obtenir une résolution de l'ordre du micromètre dans l'eau (comparable à la...

Experimental investigation of stochastic resonance in a 65 nm CMOS artificial neuron

Sara Hedayat, Ilias Sourikopoulos, Christophe Loyez, Francois Danneville, Laurent Clavier, Virginie Hoel, A. Cappy

This work proposes an experimental demonstration of the stochastic resonance, a phenomenon widely observed in biology using a 65 nm CMOS artificial neuron. The stochastic resonance has been revealed through two different statistical studies. Moreover, when optimal, a signal to noise ratio at the...

A 130 to 170 GHz integrated noise source based on avalanche silicon Schottky diode in BiCMOS 55 nm for in-situ noise characterization

Joao Carlos Azevedo Goncalves, Thomas Quemerais, Daniel Gloria, Gregory Avenier, Sylvie Lepilliet, Guillaume Ducournau, Christophe Gaquière, Francois Danneville

In this paper, an integrated noise source realized with silicon Schottky diodes is presented. To this aim, dedicated test structures have been designed and characterized; the corresponding Schottky diodes feature an avalanche breakdown voltage close to -6 V. When biased around this breakdown...

Finite element modeling of a piezoelectric slender bar transducer equipped with a multilayer backing for medical imaging applications

Nadia El Atlas, Abdelmajid Bybi, Hilal Drissi, Anne-Christine Hladky

The goal of this work is to investigate the impact of front and back matching layers properties on a piezoelectric slender bar transducer performances and to propose a novel multilayer backing absorber. Quarter-wavelength acoustic matching layers and backing are known as essential components to...

New adaptive filters as perceptual preprocessing for rate-quality performance optimization of video coding

Eloïse Vidal, Nicolas Sturmel, Christine Guillemot, Patrick Corlay, François-Xavier Coudoux

In this paper, we introduce two perceptual filters as pre-processing techniques to reduce the bitrate of compressed high-definition (HD) video sequences at constant visual quality. The goal of these perceptual filters is to remove spurious noise and insignificant details from the original video...

3D patterning of silicon by contact etching with anodically biased nanoporous gold electrodes

Encarnación Torralba, Mathieu Halbwax, Taha El Assimi, Marin Fouchier, Vincent Magnin, Joseph Harari, Jean-Pierre Vilcot, Sylvain Le Gall, Raphaël Lachaume, Christine Cachet-Vivier, Stéphane Bastide

A novel strategy to achieve 3D pattern transfer into silicon in a single step without using lithography is presented. Etching is performed electrochemically in HF media by contacting silicon with a positively biased, patterned, metal electrode. Dissolution is localized at the Si/metal contacts and...

Pinces acoustiques à ondes de surface tourbillonnaires pour la manipulation sélective et sans contact de microparticules et cellules

Antoine Riaud, Michael Baudoin, Jean-Louis Thomas, Matar, Olivier Bou

La manipulation de particules, de cellules, de gouttelettes ou de bulles est une opération clefs dans de nombreux domaines tels que la biologie cellulaire, la biologie des micro-organismes, la microfluidique, le génie chimique ou encore les microsystèmes. En particulier, la manipulation sélective d...
