Retention or repulsion forces induced by bubbles trapped at the base of an immersed microparticle on a substrate

Anna Ipatova, Alexis Duchesne, H N Yoshikawa, Pascal Mariot, Corenthin Leroy, Christine Faille, Ichiro Ueno, Georg F Dietze, Farzam Zoueshtiagh

We explore the potential for air bubble entrapment beneath micrometer-sized particles following immersion. This investigation employs theoretical, numerical, and experimental methodologies, with a focus on the wetting characteristics of both the particle and its substrate. These properties are…

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…

Time-encoded electrical detection of trace RNA biomarker by integrating programmable molecular amplifier on chip

Gurpreet Kaur, Marcel Tintelott, Mohit Suranglikar, Antoine Masurier, Xuan-Thang Vu, Guillaume Gines, Yannick Rondelez, Sven Ingebrandt, Yannick Coffinier, Vivek Pachauri, Alexis Vlandas

One of the serious challenges facing modern point-of-care (PoC) molecular diagnostic platforms relate to reliable detection of low concentration biomarkers such as nucleic acids or proteins in biological samples. Non-specific analyte-receptor interactions due to competitive binding in the presence…

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…

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…

Electrochemical impedance spectroscopy of an evolving conducting polymer dendrite in water

Antoine Baron, Sébastien Pecqueur

Deposition of PEDOT:PSS is triggered alternatively on two gold wires distant of 240 µm from each other. The gold wires are immersed in a drop of water containing 10 mM of EDOT, 1 mM of sodium polystyrene sulfonate (NaPSS) and 10 mM of benzoquinone (BQ). The growth is captured with a camera and the…

Enhanced Fluid Characterization with a Cantilever Microbeaman System Excited by an Embedded Electroactive Source

Victory Elias, Emmanuel Dubois, Nikolay Smagin, Frédéric Rivart, Alex Vercampt, Georges Nassar

When there is a variation in fluid concentration at the free end of a microcantilever, this phenomenon can be utilized in applications such as chemical analysis, biological testing, pharmaceutical screenings, and environmental monitoring. This paper introduces a novel sensor based on a silicon…

In this paper, we report an analysis of reverse current mechanisms observed in GaN Schottky barrier diodes leading to hysteretic behavior of the I\textendashV curves at low temperature. By means of DC measurements from 33 to 475\,K, we demonstrate the presence of two leakage mechanisms when…
