Dynamic thermoregulatory photonic crystal fabric for personal thermal management

Mohamed Boutghatin, Yan Pennec, Salim Assaf, Michèle Carette, V. Thomy, Abdellatif Akjouj, Bahram Djafari-Rouhani

Personal thermal management represents a new paradigm to reduce the energy consumption, which consists in controlling the temperature around the human body rather than regulating the temperature of the entire residential space. Recent progress in smart textile showed promising radiative heating and…

Bias Tunable Spectral Response of Nanocrystal Array in a Plasmonic Cavity

Tung Huu Dang, Angela Vasanelli, Yanko Todorov, Carlo Sirtori, Yoann Prado, Audrey Chu, Charlie Gréboval, Adrien Khalili, Herve Cruguel, Christophe Delerue, Gregory Vincent, Emmanuel Lhuillier

Nanocrystals (NCs) have gained considerable attention for their broadly tunable absorption from the UV to the THz range. Nevertheless, their optical features suffer from a lack of tunability once integrated into optoelectronic devices. Here, we show that tunable absorption with bias can be obtained…

Third order notch over multi-bias and temperature in GaN and GaAs HEMTs

M.A. Alim, A.A. Rezazadeh, Christophe Gaquière

A detailed study about the shifting of third-order notch and threshold voltage with temperature for GaN and GaAs FETs were analyzed. For this purpose, a great deal of data over temperature between-40 to 150°C were measured by using two-tone intermodulation distortion set up. It was found that the…

Roll-to-roll in-line implementation of microwave free-space non-destructive evaluation of conductive composite thin layer materials

Grigorios Koutsoukis, Ivan Alic, Antonios Vavouliotis, Ferry Kienberger, Kamel Haddadi

A free-space microwave nondestructive testing and evaluation module is developed for the low-power, non-ionizing, contactless, and real-time characterization of doped composite thin-film materials in an industrial context. The instrumentation proposed is built up with a handled vector network…

Signals to Spikes for Neuromorphic Regulated Reservoir Computing and EMG Hand Gesture Recognition

N. Garg, I. Balafrej, Y. Beilliard, Dominique Drouin, F. Alibart, J. Rouat

Surface electromyogram (sEMG) signals result from muscle movement and hence they are an ideal candidate for benchmarking event-driven sensing and computing. We propose a simple yet novel approach for optimizing the spike encoding algorithm's hyper-parameters inspired by the readout layer…

ESD mm-wave-circuit protection: 3-dB couplers

Marc Margalef-Rovira, Géraldine Pelletier, Vanessa Avramovic, Sylvie Lepilliet, Johan Bourgeat, Jean-Marc Duchamp, Manuel J. Barragan, Emmanuel Pistono, Sylvain Bourdel, Christophe Gaquière, Philippe Ferrari

This article presents an innovative architecture for the implementation of an electrostatic discharge (ESD) protection for millimeter-wave (mm-wave) devices. The proposed architecture is based on the use of 3-dB couplers, whose coupled outputs have been shorted to the ground node. In order to…

Securing Deep Spiking Neural Networks against Adversarial Attacks through Inherent Structural Parameters

R. El-Allami, A. Marchisio, M. Shafique, Ihsen Alouani

Deep Learning (DL) algorithms have gained popularity owing to their practical problem-solving capacity. However, they suffer from a serious integrity threat, i.e., their vulnerability to adversarial attacks. In the quest for DL trustworthiness, recent works claimed the inherent robustness of…

Human sensing in reverberant environments: RF-based occupancy and fall detection in ships

Marwan Yusuf, Emmeric Tanghe, Brecht de Beelde, Pierre Laly, Matteo Ridolfi, Eli de Poorter, Luc Martens, Davy Gaillot, M. Lienard, Wout Joseph

In this paper, we explore the possibility of estimating the number of people inside a below-deck ship compartment using the theory of room electromagnetics. Most RF-based occupancy detection solutions focus on residential environments. Confined metallic spaces such in industrial environments are…
