Ultra-Low-Power Neuromorphic Spike Detector for Large-Scale Neural Interfaces

Louis Regnacq, Hicham Lahrach, Anna Kobzar, Nicolas Lefoulon, Rédha Kassi, Pascal Mariot, A. Cappy, Christel Vanbesien, Alexis Vlandas, Christophe Loyez, Virginie Hoel

This work presents an ultra-low-power analog neuromorphic architecture for spike detection in large-scale neural interfaces. The goal is to reduce the amount of data transmitted by the implant by sending only detected spike timestamps. The proposed approach is inspired by sensory neurons connected...

Stabilization of the Li3PS4/Li interface by a 4 nm Al2O3 coating studied by in situ HAXPES

Lucía Pérez Ramírez, Jonas Sottmann, Benjamin Hennequart, Muath Radi, Maxime Hallot, Christophe Lethien, Lenart Dudy, Jean-Pascal Rueff, Rémi Dedryvère

Li-metal based All-Solid-State Batteries (ASSBs) offer a safer and higher-energy alternative to conventional lithium-ion batteries, but their performances are hindered by interfacial instability between the solid-state electrolyte (SSE) and lithium metal electrode. To stabilize the interface, a...

Realizing high performance flexible multilevel memory based on charge storage in Au nanoparticles and electrets

Shuo Li, Khaoula Ferchichi, Hui Zhang, You Yin, Kamal Lmimouni

In this paper, we report on the pentacene-based field-effect transistors (FETs) and flexible nano-floating gate-based transistor memory (NFGM) devices that were fabricated on ultra-flexible 2 μm Parylene C, deposited on different substrates. All thin-film layers can be deposited at low temperatures...

Investigation of thickness dependences of interfacial magnetic properties of ( Pt / Co / W ) 5 -based multilayers

R. Sbiaa, W. Fotso, M. Hafiz, M. Ramu, Nicolas Tiercelin, S. Chérif, A. Lisfi, Y. Roussigné, S. Piramanayagam, M. Belmeguenai

We investigated the thickness dependences of the interfacial Dzyaloshinskii-Moriya interaction (DMI) and the perpendicular magnetic anisotropy (PMA) in (Pt/Co/W)5 multilayers by systematically varying the Co (from 1.3 to 1.9 nm) and W (from 0 to 3 nm) layer thicknesses. Vibrating sample...

Implementation of Reservoir Computing Using Coupled Microelectromechanical Drum Resonators via Sideband-Pumped Phonon-Cavity Dynamics

Theresa Farah, Loïc Flis, Pierre Laly, Guo-En Chang, Jun-Yu Ou, Yoshishige Tsuchiya, Yan Pennec, Bahram Djafari-Rouhani, Xin Zhou

Reservoir computing is a bio-inspired machine learning paradigm that exploits the intrinsic dynamics of nonlinear systems with fading memory for efficient temporal information processing. Microelectromechanical resonators offer a promising platform for reservoir computing as they inherently possess...

We report the demonstration and analysis by combined scanning-tunneling-microscopy and optical microspectroscopy of a 2D phase change experienced by a self-assembled zinc phthalocyanine (ZnPc) monolayer adsorbed on graphene. To probe the intrinsic properties of individual ZnPc molecules, they are..., Nous présentons la démonstration et l'analyse, par une combinaison de microscopie à effet tunnel et de microspectroscopie optique, d'un changement de phase bidimensionnel observé dans une monocouche auto-assemblée de phtalocyanine de zinc (ZnPc) adsorbée sur du graphène.
