Neuromorphic Signal Classification using Organic Electrochemical Transistor Array and Spiking Neural Simulations

Mahdi Ghazal, Ankush Kumar, Nikhil Garg, Sébastien Pecqueur, Fabien Alibart

Neuromorphic computing is an exciting and rapidly growing field that aims to create computing systems that can replicate the complex and dynamic behavior of the human brain. Organic electrochemicaltransistors (OECTs) have emerged as a promising tool for developing such systems due to their unique...

Thermoelectric Properties of Benzothieno-Benzothiophene Self-Assembled Monolayers in Molecular Junctions

Sergio Gonzalez-Casal, Rémy Jouclas, Imane Arbouch, Yves Geerts, Colin van Dyck, Jérôme Cornil, Dominique Vuillaume

We report a combined experimental (C-AFM and SThM) and theoretical (DFT) study of the thermoelectric properties of molecular junctions made of self-assembled monolayers on Au of thiolated benzothieno-benzothiophene (BTBT) and alkylated BTBT derivatives (C8-BTBT-C8). We measure the thermal...

Fault detection and localization in unshielded twisted pair cable based on observability analysis and reflectometry experimental measurements.

Hermine Judith Idellette Som, Vincent Cocquempot, Virginie Degardin

In this paper, an efficient method is proposed for detecting and locating a soft fault, i.e. a physical degradation, in a Y -shaped network of unshielded twisted pair cables. The method uses jointly the observability analysis and time-frequency domain reflectometry experimental measurements. The...

An Incremental Time-Domain Mixed-Signal Matrix-Vector-Multiplication Technique for Low-Power Edge-AI

Kévin Hérissé, Benoit Larras, Bruno Stefanelli, Andreas Kaiser, Antoine Frappé

This paper proposes a time-domain mixed-signal computing architecture for Matrix-Vector Multiplication suited for embedded in-memory computing applications. The system leverages the low data rate of sensors’ data in embedded AI applications to target an energy-efficient implementation of the matrix...

Reliable and robust integration of SAW strain sensor through reflow soldering

Othmane Marbouh, A. Mazzamurro, Y. Dusch, O. Bou Matar, N. Tiercelin, V. Maurice, P. Pernod, R. Viard, D. Laloy, K. Ettihir, A. Tounzi, A. Benabou, A. Talbi

Surface Acoustic Wave (SAW) sensors represent a prominent technological avenue for quantifying mechanical stress-induced deformations. Nonetheless, the integration of these Micro-Electro-Mechanical Systems (MEMS) sensors remains an complex challenge. Consequently, a common approach within a...

Fabry-Pérot and Friedrich-Wintgen bound states in the continuum in a photonic triple-stub cavity

Yamina Rezzouk, Soufyane Khattou, Mohamed El Ghafiani, Madiha Amrani, El Houssaine El Boudouti, Abdelkrim Talbi, Bahram Djafari-Rouhani

Bound states in the continuum (BICs) are zero-width (infinite lifetime) trapped eigenmodes that remain conf ined in the system even though they coexist with a continuum of extended states. The resulting high-frequency resonances may have significant applications in photonic integrated circuits,...

Enhancing Tamm Plasmon Sensor Performance using Nanostructured Gold Grating and Porous Materials

O. Haidar, Baptiste Mathmann, Yannick Dusch, Mohamed El Barghouti, Romain Viard, Gaëtan Lévêque, El Houssaine El Boudouti, Abdellah A. Mir, A. Talbi, Abdellatif Akjouj

In this paper, we introduce a gas sensor concept consisting of a nanostructured gold grating coupled with a Distributed Bragg Reflector. This coupling makes it possible to obtain plasmonic Tamm states where excitation is possible at normal incidence and does not require the use of Kretschmann...

Exploring the properties of higher-order Tamm plasmons for liquid and gas detection

O. Haidar, Baptiste Mathmann, Y. Dusch, Mohamed Boutghatin, E. Boudouti, G. Lévêque, A. Mir, A. Akjouj, A. Talbi

In this study, we present a numerical analysis of the higher-order Tamm plasmons for the design of a gas and liquid sensor. These plasmons are induced by a structure consisting of a cavity placed between the SiO2/Si3N4 Bragg grating and a finite layer of gold. This configuration is excited without...

Continuously Beam-Steered Phased Array Antenna Using GaN Varactors for Millimeter-Wave Applications

Abdelaziz Hamdoun, F Medjdoub, Mohamed Himdi, Malek Zegaoui, Olivier Lafond

A continuously steerable beam patch antenna array employing a classical phase shifter based on GaN HEMTs is presented. Here, the GaN HEMTs are used as varactor diodes to achieve the tunability purpose. By controlling the DC bias of these varactors from −2 V to 2 V, the proposed array antenna can...
