Long-range electron transport in Prussian blue analog nanocrystals

Roméo Bonnet, Stéphane Lenfant, Sandra Mazérat, Talal Mallah, Dominique Vuillaume

We report electron transport measurements through nano-scale devices consisting of 1 to 3 Prussian blue analog (PBA) nanoparticles connected between two electrodes. We compare two types of cubic nanoparticles, CsCoIIIFeII (15 nm) and CsNiII...

Characterization of 1-3 Piezocomposite Using Lamb Waves Propagation

Rémi Rouffaud, Anne-Christine Hladky, Dominique Certon, Antoine Balé, Franck Levassort

Due to their enhanced electromechanical properties with respect to conventional piezoelectric ceramics, 1-3 piezocomposite (1-3PC) materials are predominant in high performance ultrasonic array. Their complete effective electroelastic modulus (EEM) has a significant importance for numerical...

Experimental observation and modeling of the impact of traps on static and analog/HF performance of graphene transistors

Anibal Pacheco-Sanchez, Nikolaos Mavredakis, Pedro C. Feijoo, Wei Wei, Emiliano Pallecchi, Henri Happy, David Jimenez

The trap-induced hysteresis on the performance of a graphene field-effect transistor is experimentally diminished here by applying consecutive gate-to-source voltage pulses of opposing polarity. This measurement scheme is a practical and suitable approach to obtain reproducible device...

Cyclostationary-based vital signs detection using microwave radar at 2.5 GHz

Fatima Sekak, Kawtar Zerhouni, Fouzia Elbahhar, Madjid Haddad, Christophe Loyez, Kamel Haddadi

Non-contact detection and estimation of vital signs such as respiratory and cardiac frequencies is a powerful tool for surveillance applications. In particular, the continuous wave bio-radar has been widely investigated to determine the physiological parameters in a non-contact manner. Since the RF...

Demonstrating full integration process for electroactive polymer microtransducers to realize soft microchips

Lauréline Seurre, Kätlin Rohtlaid, Giao T. M. Nguyen, Caroline Soyer, Sofiane Ghenna, Sébastien Grondel, Frederic Vidal, Barthelemy Cagneau, Cedric Plesse, Eric Cattan

Actuation and sensing with electroactive polymers should be a chance for flexible MEMS but their micromachining and integration are still not mature. Some innovative materials and microfabrication processes are still expected. In this paper, a first full elaboration of polymeric microtransducers (...

Distributed clique-based neural networks for data fusion at the edge

Benoit Larras

Distributed smart sensors are more and more used in applications such as biomedical or domestic monitoring. However, each sensor broadcasts data wirelessly to the others or to an aggregator, which leads to energy-hungry sensors not ensuring data privacy. To tackle both challenges, this work...

Compact multichannel spectroscopic label-free biosensor platform for plant diseases point-of-care testing (POCT)

Jurij Hastanin, Cedric Lenaerts, Patrick Gailly, Frédéric Rabecki, Aline Roobroeck, Sylvain Desprez, Damien Bernier, Fabian Dortu, Camille Dekuijper, Deborah Lanterbecq, Karine Lecointe, Boualem Sendid, Mohamed Bouazaoui, Sophie Maricot, Mohamed-Taieb Bakouche, Sivaramakrishnan Ganesan, Jean-Pierre Vilcot, Karl Fleury-Frenette

The POCT technology involving low cost Lab-On-Chip label-free biosensing opens up an opportunity to drastically reduce the total cost of plant health and disease monitoring tools. The main requirement for a POCT tool is that it should involve relatively inexpensive equipment ensuring a sufficiently...

Conductive filament evolution dynamics revealed by cryogenic (1.5 K) multilevel switching of CMOS-compatible Al 2 O 3 /TiO 2 resistive memories

Yann Beilliard, François Paquette, Frédéric Brousseau, Serge Ecoffey, F. Alibart, Dominique Drouin

Non-volatile resistive switching devices are considered as prime candidates for next-generation memory applications operating at room temperature and above, such as resistive random-access memories or brain-inspired in-memory computing. However, their operability in cryogenic conditions remains to...
