Tunable photo-responsive elastic metamaterials

Antonio S. Gliozzi, M. Miniaci, Annalisa Chiappone, Andrea Bergamini, Benjamin Morin, Emiliano Descrovi

The metamaterial paradigm has allowed an unprecedented space-time control of various physical fields, including elastic and acoustic waves. Despite the wide variety of metamaterial configurations proposed so far, most of the existing solutions display a frequency response that cannot be tuned, once...

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...

Validating the CorrectWearing of Protection Mask by Taking a Selfie: Design of a Mobile Application “CheckYourMask” to Limit the Spread of COVID-19

Karim Hammoudi, Adnane Cabani, Halim Benhabiles, Mahmoud Melkemi

In a context of a virus that is transmissive by sputtering, wearing masks appear necessary to protect the wearer and to limit the propagation of the disease. Currently, we are facing the 2019–2020 coronavirus pandemic. Coronavirus disease 2019 (COVID-19) is an infectious disease with first symptoms...

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...

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...

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...

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...
